Test and tagging is done to reduce the risk of electric shock from faulty appliances and to comply with occupational health and safety legislation.
Practical Electrical Substation Safety for Engineers and TechniciansLiving Online
Electrical substation safety is an important issue in utility networks as well as large industrial installations and requires adequate attention in the stages of system planning, design, installation, operation and maintenance. A number of serious accidents including fatalities occur every year in industrial establishments due to accidents involving electricity, resulting in huge financial losses and wasted man-hours. Electrical safety is a well-legislated subject and the various Acts and Regulations lay a lot of stress on the responsibility of both employers and employees in ensuring safe working conditions.
In this workshop, we will take a look at the theoretical aspects of safety as well as the practical and statutory issues. Safety is not simply a matter of taking precautions in the workplace. It has to start at the stage of equipment design. Safety should be built into the design of electrical equipment and it is the responsibility of every manufacturer of electrical equipment to remove every possible hazard that can arise from its normal use. Correct selection and application of electrical machinery is also important for ensuring safety. A thorough inspection during initial erection and commissioning as well as on a periodic basis thereafter is also very essential to ensure safety. Batteries used in substations need particular attention since they contain toxic materials such as lead, corrosive chemicals such as acid or alkali.
Electrical safety is not just a technical issue. Accidents can only be prevented if appropriate safety procedures are evolved and enforced. This includes appropriate knowledge of equipment and systems imparted through systematic training to each and every person who operates or maintains the equipment. We will cover all these aspects in detail.

Electricity is a natural and man-made energy force that is essential to modern life. Electrical hazards are one of the greatest risks on construction sites and can lead to electrocutions. Each year in the United States, over 200 workers die from electrocutions, with construction workers making up around one third of those deaths. Common electrical hazards include damaged or improper insulation, exposed electrical parts, inadequate wiring, overloaded circuits, wet conditions, and contact with overhead power lines. Workers can reduce electrical risks by properly grounding equipment, avoiding exposed wires, using extension cords and power tools appropriately, and staying clear of overhead lines. Personal protective equipment like insulating gloves and hardhats can also help prevent electrocution.
This document provides information on electrical hazards, which are one of the biggest hazards on construction sites. It discusses common electrical hazards such as improper grounding, exposed electrical parts, inadequate wiring, overloaded circuits, damaged tools and equipment, wet conditions, and overhead power lines. It emphasizes the importance of accident prevention methods like using personal protective equipment, inspecting tools and cords, ground fault circuit interrupters, and lock-out/tag-out procedures. The document aims to help workers recognize electrical hazards and prevent electrical accidents and injuries.
The tall wiring fences that surround electrical substations suggest that such places are not accessible to the public. Let it be known that substations are extremely dangerous and the safety signs will tell you that. The signs read as either “Danger”, “Caution”, “Warning”, “No Entry”, or “High Voltage Risk Ahead”. The various machineries inside the facility carry high voltage risks, and trespassers who dare to come near the place put themselves in danger.

Avoiding danger from underground services.amoramart
This book updates the guidance contained in the previous edition of HSG47 Avoiding danger from underground services. It outlines the dangers which can arise from work near underground services and gives advice on how to reduce the risk. It deals only with risks to the health and safety of people and is not concerned with damage which has no direct risks associated with it. However; precautions taken which reduce risks to the health and safety of people will generally also reduce the risk of damage to services. Remember too that damage can have a knock-on effect: consider for example the effect of the loss of a telephone service if a 999 call has to be made.
Operating Cranes and Plant near Overhead Electric Linespeterswork1
Operating cranes and machinery near overhead power lines poses a serious risk of electrocution. It is difficult for operators to accurately judge distances between equipment and power lines. Employers must identify risks, conduct a written risk assessment considering factors like minimum clearance distances and load stability, and implement measures to eliminate or minimize risks, such as de-energizing lines or isolating hazards with physical barriers. Ongoing monitoring is also needed to ensure risk treatment measures remain effective as work sites change.

COMPENSATION OF FAULT RESISTANCE IN DISTANCE RELAY FOR LONG TRANSMISSION LINEIRJET Journal
This document discusses distance protection for long transmission lines and the impact of fault resistance. It begins with an introduction to distance relaying and the issues caused by fault resistance. It then discusses the objectives of analyzing how fault resistance affects protection at different fault distances. The document proposes a new algorithm to estimate fault location and resistance using voltage and current measurements from two terminals. The algorithm compensates for fault resistance in mho-type distance relays by measuring apparent impedance and subtracting the estimated fault resistance. This improves the accuracy of distance protection for faults with resistance on long transmission lines.

Different earthing options are described such as direct earthing, earthing through a reactor, and earthing through a resistor. Fault currents are calculated using a simplified method to determine protection settings and ensure selectivity.
The document discusses grounding systems and their importance. It covers three main types of grounding: protective grounding, which protects equipment and personnel from electric shock; signal grounding, which provides a common reference point for electronic circuits; and lightning grounding, which protects systems from lightning strikes. Protective grounding is achieved through grounding electrodes that provide a low impedance path for fault currents. The document outlines factors that influence soil resistivity and techniques for measuring and reducing ground resistance.
- The document discusses the application and coordination of primary fuses.
- It describes how fuse links act as protective devices, protecting equipment from overcurrent and isolating faults. The time-current characteristics of fuse links must be selected to provide coordination between protective devices.
- Transformers and sectionalizing fuses are discussed as common applications. Dual-characteristic fuses like SloFast are described as providing better protection of transformers compared to standard fuses. Coordination between protecting and protected fuses is also explained.
Surge Protection for Fieldbus Systems - ICA 2006Alvin CJ Chin
The document discusses surge protection considerations for fieldbus systems. It begins by outlining the benefits of fieldbus systems but notes that reliability in harsh lightning-prone environments is not well understood. It then covers the probability of lightning strikes based on location, the types of damage lightning-induced surges can cause, and the need to consider every point where a surge could invade the system. The document advocates performing a risk analysis to determine if surge protection is needed based on the likelihood of damage and cost of protection versus repair. It also notes that fieldbus systems have more potential points of entry for surges compared to conventional wiring.
This document outlines standards for transmission line grounding. It discusses the purposes of grounding systems, which are to safeguard people from electric shock during faults, dissipate fault currents and voltages within limits, provide a path for lightning and switching surges, and reduce static discharge. It covers fundamental considerations like soil properties, power system networks, grounding performance of structures, and types of disturbances. Specific sections address safety, grounding of different structure types, grounding conductors, electrodes, resistance requirements, and recommended conductor sizes.
Detection of Underground Cable Fault using ArduinoIRJET Journal
This document describes a system to detect faults in underground cables using an Arduino. It uses Ohm's law - a voltage is applied to the cable and the current measured to determine faults. Resistors represent distances along the cable where fault switches can induce faults. When a fault occurs, the voltage change is read by the Arduino and the fault location displayed on an LCD in kilometers. The system can detect common fault types like line-ground and line-line faults. It is meant to more easily locate underground cable faults compared to traditional methods that require digging to find faults.
critical protection for medium voltage network.pdfLittleBro2
This document discusses protection criteria for medium voltage networks. It describes different types of network schemes, including single radial networks, double radial networks, ring networks, and meshed networks. It explains the advantages and disadvantages of each type. It also covers topics like selection of switching devices, current and voltage transformers, short circuits, neutral grounding methods, protection relay codes, and philosophies of protection settings like time selectivity and current selectivity. The overall aim is to illustrate the basic criteria needed for good protection of machines and plants in medium voltage networks.
System design-engineering-j jicable11-0279_final-evolution-in-method-performa...nak maneth
This document discusses developments in bonding methods for underground power cable screens that allow for longer cable shipping lengths. It presents:
1) Direct cross-bonding, which reduces joint protections by relying on the dielectric strength of screen interruptions. This requires accurate modeling of overvoltages.
2) Studies showing screen interruptions can withstand overvoltages from lightning strikes and faults without surge arresters in some cases.
3) Novel direct bonding designs that connect screen sections directly instead of using concentric leads, reducing costs while maintaining functionality.
This document discusses protection criteria for medium voltage networks. It covers different types of network schemes including single radial, double radial, ring and meshed networks. It describes the advantages and disadvantages of each. It also discusses various protection devices and strategies used in medium voltage networks, including current and voltage transformers, short-circuit protection, neutral grounding methods, protection relay codes, and selectivity of protection settings. The goal is to illustrate criteria for properly protecting machines and plants in medium voltage networks by selecting appropriate protection systems and relays based on network characteristics.
This document discusses methods for protecting water and wastewater treatment plants from lightning strikes and electrical surges. It identifies areas at high risk for lightning strikes, such as pump lift stations and radio antennas. Traditional surge protection methods using MOVs and SADs can be overwhelmed by lightning strikes. Newer triggered arc gap technology provides better protection against high-energy lightning strikes by diverting surge currents to ground. The document describes how triggered arc gaps and additional surge protectors were installed to protect a water treatment plant in Florida that experienced frequent lightning damage.
Surge protection can improve reliability, availability, and return on assets (ROA) for process plants. Surges are a leading cause of up to 30% of premature electronics failures. While techniques like lightning protection, bonding, and UPS systems help mitigate surges, they do not eliminate the risk. Strategically applying surge protection, especially for critical assets or those at high risk, can directly reduce failures and increase availability. This improves ROA by minimizing downtime and maintenance costs. Prioritizing protection based on asset impact and risk exposure maximizes the financial benefits of surge protection.
Successful operation of entire power system depends to a considerable extent on efficient and satisfactory performance of substations. Hence substations in general can be considered as heart of overall power system. In any substation, a well-designed grounding plays an important role. Since absence of safe and effective grounding system can result in mal-operation or non-operation of control and protective devices, grounding system design deserves considerable attention for all the substations. There are two primary functions of a safe earthing system. Firstly, ensure that a person who is in the vicinity of earthed facilities during a fault is not exposed to the possibility of a fatal electrical shock. Secondly, provide a low impedance path to earth for currents occurring under normal and fault conditions.The earthing conductors, composing the grid and connections to all equipment and structures, must possess sufficient thermal capacity to pass the highest fault current for the required time
An experienced street lighting team’s perspective -
Scotland has a strong focus on accelerating the provision of electric vehicle charging infrastructure. Data shows that outside of London, Scotland is way ahead of the rest of the UK in the provision of public charge points. So, what can be learnt from Westminster’s EV charging rollout? The process has been managed by a specific team, with technical input from the council’s street lighting team. This CPD presentation will give the street lighting team’s view of the in-column EV charging rollout in the council. Covering the expectations versus reality under current standards, the issues found following installation, and the ever-changing landscape of what can be allowed on the highway, this session will benefit every street lighting professional with an involvement in EV charging. The webinar will also include an overview of the issues to consider with rapid chargers.

Remediation of Old Substations for Arc Flash hazardIJAPEJOURNAL
Arc Flash is much different from the conventional shock hazard in the sense that it doesn’t involve direct contact of human beings with the live or energized part. The arcing energy involves high temperature of up to or beyond 20000K. This paper presents a case study of arc flash hazard analysis carried out in older industrial plant and the technological and work procedure changes that can be incorporated to reduce the incident energy level and thus provide a safer environment for the working personnels in plant.
Controlled blasting techniques can be used to mitigate adverse impacts of blasting in mining and construction. These include line drilling, trim blasting, smooth blasting, pre-splitting, optimizing blast design parameters, accurate timing delays, and muffle blasting. Signature hole analysis uses monitoring of a pilot blast to model blast vibration and optimize delay timing to reduce vibration energy at structural resonance frequencies. Adopting controlled blasting techniques can help restrict ground vibrations and overbreak while improving safety, environmental, and economic outcomes.
The document discusses swing angle-clearance combinations specified for transmission lines in India. It analyzes how the combinations impact tower configuration and whether all specified combinations are necessary. The analysis shows that for most line voltages, only two judiciously selected swing angle-clearance combinations are sufficient to determine optimal tower configuration. The remaining extra combinations specified do not affect tower design and could be removed without compromising reliability. Using only two critical combinations could simplify transmission line design processes.
This document provides guidance on site sampling and testing of concrete according to British and European standards. It discusses safety precautions when working with concrete, describes the standard procedures for sampling concrete from delivery trucks and performing slump and flow tests, and lists the necessary equipment. Key points include:
- Protective clothing should be worn as alkalis in concrete can harm skin and eyes.
- For sampling, scoops should be taken from four different parts of the load as it is discharged.
- For slump tests, the sample is remixed and placed in three layers in a slump cone, which is then lifted and the slump measured.
- For flow tests, the sample is placed in two layers in
The document provides guidance on site sampling and testing of concrete, including procedures for sampling, slump testing, flow testing, making cubes, storing cubes, and safety information. The key points are:
1) Sampling should be done according to BS1881:Part 101 or BSEN 12350-1 by taking scoopfuls from four parts of the load and mixing in a bucket.
2) Slump testing involves mixing the sample, filling a cone in layers and rodding each layer, lifting the cone and measuring the slump distance.
3) Flow testing uses a similar process of filling a mould and tamping layers, but then lifts the mould and counts drops to measure spread
This guide provides information on working safely near overhead power lines. It outlines key precautions including assessing safe distances, using a safety observer, and calling the electricity supplier before working in restricted zones. If contact is made with power lines, the guide instructs workers to call for help and not touch any equipment until the lines are deactivated. Employers and workers both have legal responsibilities to ensure a safe work environment when near overhead power lines.
The document provides a risk register for an overhead transmission line project. It identifies 5 main risks:
1) Changes to the approved foundation design could delay the project.
2) Introducing new foundation design software not specified in the contract could lead to delays from additional engineering work.
3) Selecting the route alignment without a proper survey could result in delays from suboptimal tower positions.
4) Using an incompetent project team without experience in overhead line construction in hilly areas could impact the project.
5) Not deploying sufficient machinery for civil works like access roads and excavation in hilly terrain could slow progress.
This document contains a risk register for an overhead transmission line project with 16 identified risks. The top 3 risks are:
1) Changes to the approved foundation design after work has commenced could delay the project due to changes in scope.
2) Introduction of new software not specified in the contract could delay the project as it would require additional engineering work and study time.
3) Passing new comments on design revisions may lead to design delays and delays in execution if not properly managed.
The document describes a series of dynamic centrifuge tests that examined methods to reduce settlement of power transmission tower foundations during earthquakes. The tests modeled four isolated tower footing foundations on a liquefiable sand layer. Three countermeasure types were examined: 1) a base plate connecting the footings, 2) a surface plate connecting the footings at ground level, and 3) a surface plate with surrounding sheet piles. Test results showed that the base plate reduced settlement by up to 70% while the surface plate reduced it by 30%. The surrounding sheet piles showed relatively small effectiveness due to inadequate length compared to the foundation width.

Bram Verhoef, Head of Machine Learning at Axelera AI, presents the “How Axelera AI Uses Digital Compute-in-memory to Deliver Fast and Energy-efficient Computer Vision” tutorial at the May 2024 Embedded Vision Summit.
As artificial intelligence inference transitions from cloud environments to edge locations, computer vision applications achieve heightened responsiveness, reliability and privacy. This migration, however, introduces the challenge of operating within the stringent confines of resource constraints typical at the edge, including small form factors, low energy budgets and diminished memory and computational capacities. Axelera AI addresses these challenges through an innovative approach of performing digital computations within memory itself. This technique facilitates the realization of high-performance, energy-efficient and cost-effective computer vision capabilities at the thin and thick edge, extending the frontier of what is achievable with current technologies.
In this presentation, Verhoef unveils his company’s pioneering chip technology and demonstrates its capacity to deliver exceptional frames-per-second performance across a range of standard computer vision networks typical of applications in security, surveillance and the industrial sector. This shows that advanced computer vision can be accessible and efficient, even at the very edge of our technological ecosystem.
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?

Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.

WORKING NEAR OVERHEAD LINES
1. Introduction
People are killed and injured each year by accidental contact with overhead
electrical lines. Most of these accidents occur when cranes, excavators, tipper
trucks, crane mounted lorries, mobile extendable machinery, scaffolding,
ladders, farm machinery, concrete delivery trucks etc. come close to or touch
live overhead lines. Such accidents are caused by failure to take all practicable
precautions to prevent accidental contact with these lines. Recommended
methods and procedures are set out in this booklet which, if adopted, will
provide a positive approach to the elimination of these tragedies.
NOTE: GUARD AGAINST WORKING CLOSE TO LIVE OVERHEAD LINES.
IF AT ALL POSSIBLE KEEP MACHINERY WELL AWAY (OUTSIDE THEIR
REACH). PLAN THE WORK IN ADVANCE AND STAY SAFE.
IT IS YOUR RESPONSIBILITY TO ENSURE THAT ANY MACHINERY OR
EQUIPMENT (E.G. LADDERS, CRANES, SCAFFOLDING ETC.) SET UP
OUTSIDE THE ‘AT RISK ZONE’ (SEE SECTION 7) IS STABLE AND THAT
PRECAUTIONS ARE PUT IN PLACE TO PREVENT THEM FROM FALLING
INTO THE ‘AT RISK ZONE’.
2. Statutory Regulations
As with all work locations, there is an obligation under the Safety Health and
Welfare at Work Act 1989 to provide a safe place of work for all employees. It
is the duty of the employer when employees are working near overhead lines to
ensure that they are aware of the hazard. The erection of barriers, bunting and
goal posts as set out in chapters 6, 7, 8 and 9 of this booklet will alert
employees and the general public to the hazard and act as a warning to keep
8. overhead 23/11/04 2:28 PM Page 8
Page 6 of 20
their distance.
The General Application Regulations S.I. 44 of 1993 state in regulation 52 that
overhead lines should be protected with suitable guards and barriers so as to
prevent dangerous contact with a person, article, substance or any conducting
material.
The nine Principles of Prevention which are also contained in the 1993 General
Application Regulations S.I.44, contain requirements on the avoidance,
evaluation and elimination of risk and the adaptation of the workplace to reduce
the risk. This imposes duties on the contractor to protect his/her employees
from the dangers associated with working near overhead lines.
Under the Construction Regulations S.I. No. 481 of 2001, the Project
Supervisor (Construction Stage) must specify the control measures for dealing
with the particular risks referred to in the preliminary safety and health plan,
which may also include other significant risks associated with the project.
Working near high voltage power lines is one of the listed hazards and must be
risk assessed and the controls specified in the health and safety plan.
3. Consultation
If danger exists in the work area due to overhead electrical lines running (a) over
a site, (b) near the site boundaries or (c) over access roads to the site, it is
essential that the Contractor or person undertaking the work should consult
with ESB Networks. This consultation should take place at the planning stage
so that the proposed work can be discussed in relation to any overhead
electrical line that may exist on or near the proposed site. Such an approach will
provide an adequate time span where the line can be switched out and earthed,
but typically for only part of the day, or otherwise, i.e. that the line can be
diverted or that other precautions, as described below, can be taken.
9. overhead 23/11/04 2:28 PM Page 9
Page 7 of 20
4. Switchout of Overhead lines
If supply conditions permit the switching out of an overhead electrical line it
becomes a matter of arrangement between the Contractor and the local ESB
Networks Office. Ample advance warning concerning any requirement of this
nature is essential to allow time for changes to be made in existing feeding
methods; for informing customers whose supply or quality of supply would be
affected by the switch-out, etc.
In many instances, such outages can be granted only for a short period, e.g. 2
to 3 hours, due to loss of supply to customers over the switch-out periods and,
unfortunately, at times this option, is not available at all because of the necessity
to maintain an un-interrupted supply to particular types of customers. In general,
switching out the line is not a practical solution in situations where work in
proximity to overhead lines is on-going over a period of time.
Where the switchout of an overhead line is granted, the contractor shall wait for
confirmation by ESB Networks that the line is switched out and not assume that
it is dead at a pre-arranged time. The contractor shall be contactable at all time
during the switchout in case the ESB Networks need to switch the line back on.
5. Diversion of Overhead Lines
Where diversion of the line is a practical option, contact with ESB Networks
must be made as early as possible, e.g. at the planning stage as suggested
above. Time spans for the diversion of LV/l0kV/20kV lines can ( be up to a few
months due to wayleave serving, work load, etc., and that for higher voltages
lines can be as much as one year due to planning permission submissions,
wayleave serving, workload, etc. In certain circumstances it is impossible to
10. overhead 23/11/04 2:28 PM Page 10
Page 8 of 20
design a suitable line diversion due to the lack of an alternative route. In
addition, if the work in proximity to a line is of a particular nature, e.g. not
involving the erection of permanent structures over ground, a line diversion
would not be an appropriate or justifiable means of dealing with the problem.
Generally diversions of high voltage lines are not feasible.
6. Working in Proximity to Overhead lines
Where switching out the line or diverting the line, as discussed under 4. and 5.
above is not practicable, the precautions required to prevent accidents
involving LIVE overhead lines depend on the nature of the work. There are three
broad categories of work on site.
(a) Sites where there will be no work or passage of plant under a live line.
Here barriers are required to prevent close approach.
(b) Sites where plant will pass under a live line. Here, defined passageways
under the line must be made.
(c) Sites where work will be done beneath a live line. Here further
precautions must be taken in addition to the provision of barriers and
passageways.
7. Sites where there will be no work or passage of plant
under a Live Overhead Line (all work outside the ‘at
risk zone’)
On sites where machinery or plant may accidentally come in contact with a live
overhead line the Contractor should erect a barrier on the work side (limit of ‘at
11. overhead 23/11/04 2:28 PM Page 11
Page 9 of 20
risk zone’) at a minimum distance from the line. The barrier should run parallel
to the overhead at a minimum distance of 6 metres from the nearest conductor
of a low voltage, 10kV, 20kV and 38kV lines. This distance should be increased
to a minimum of 10 metres for voltage of 110kV, 220kV and 400kV. The
distance should be measured from the outer conductor to the barrier and not
from the centre of the pole or mast. Consult ESB Networks to confirm the
voltage of the line. These distances may be increased depending on the nature,
frequency and duration of the work. The barrier should consist of fixed post
fencing, steel drums painted red and white and filled with rubble, spaced 1.5
metres apart or other means approved by a Health and Safety Authority
Inspector. The barrier should be supplemented by notice boards indicating:
"DANGER LIVE OVERHEAD LINES", which should be spaced at intervals of
not more then 20 metres apart along the route. Where a crane, tipper truck or
other high equipment is operating in the vicinity of a live line then the barrier
should be further supplemented. This can be done with a line of bunting or
other approved means of highlighting the hazard at a minimum height of 3
metres immediately over the barrier, see Figure 1 and Figure 6.
Figure 1

8. Sites where plant will pass under a live Overhead Line
Where movement of plant is necessary under a live overhead line the
Contractor should erect wooden or other non conducting material goal posts at
the entrance to the passage on each side of the line. The goal posts should be
in line with the protection barrier as detailed in 7 above, and the wooden cross-
bar should be set at a height determined in consultation with ESB Networks.
The passageway should be as narrow as possible and should not exceed 10
metres in width and should be fenced or have steel drums on either side. Two
large warning notice boards indicating "DANGER LIVE OVERHEAD LINES"
should be placed near the goal posts at each entrance to the passage. The goal
posts should be marked in red and white stripes, See Figure 2.
Figure 2.

9. Sites where work will be done within the ‘at risk zone’
of an Overhead Line
In general when work has to be carried out close to (within the ‘at risk zone) of
a live line, ESB Networks insists on the line being switched out for the duration
of such work. In some situations, due to continuity of supply considerations, ESB
Networks may be forced to permit work underneath a live line, but only after
detailed consultation with them and with the understanding that strict safety
precautions will be employed. In addition to the precautions outlined in 7 and 8,
it will be necessary for the Contractor to erect a safety barrier underneath the
line. This barrier may be made of timber or an earthed steel net and placed at a
height determined by ESB Networks. It must be erected under the supervision
of ESB Networks so as to avoid danger of contact with the overhead line.
Generally, mobile and fixed cranes should be located in such a position that
loads cannot be slewn over live lines. If there is a need to slew over power lines,
always contact ESB Networks in advance to ensure that agreed precautions
are put in place before the slewing operation.
10. Maintenance of barriers and warning notices
In all cases covered under 7 and 8 and 9 above, a care and maintenance
system must be introduced by the Contractor in order to ensure that barriers
and warning notices remain effective for the duration of the work.
11. Special Precautions
• Always remember that, in common with electrical utilities worldwide,
ESB Network's overhead electrical lines are bare conductors. In the rare
14. overhead 23/11/04 2:28 PM Page 14
Page 12 of 20
situations where one finds covered conductors this covering is largely for
mechanical protection of the overhead line and is not a fully rated
insulation and must be treated with the same precautions as bare
conductor.
• ESB Networks must be contacted whenever it is proposed to work in the
vicinity of their overhead electrical lines.
• Contact with or coming close to overhead electrical lines can be lethal
whether they are carrying voltages as high as 400,000 volts or as low as
220 volts. High voltages in particular can arc across a distance in air, and
this makes it hazardous to come close to high voltage lines ranging from
10kV to 400kV.
• Clearance from overhead electrical lines should not be reduced by the
dumping or tipping of waste material, by landscaping operations or by
the creation of storage areas under these lines.
• Pre-planning of safe working procedures is essential.
• Liaison with ESB Networks should be continued until the construction
work has been completed.
• Access for plant and materials and the working of plant should be under
direct supervision of a responsible person appointed by the Contractor
to ensure that the safety precautions are observed.
• Self-adhesive danger stickers (obtainable free from ESB Networks) that
warn machinery operators of the hazards of working in close proximity to
overhead electrical lines should be placed on the cab window, doors or
15. overhead 23/11/04 2:28 PM Page 15
Page 13 of 20
dash of machines and vehicles.
• Before starting work in the vicinity of overhead electrical lines, machinery
operators in particular, should be briefed by their responsible supervisors
on the dangers existing and the precautions to be observed.
• In the absence of specific information provided by ESB Networks, it
must be assumed at all times that an overhead electrical line is live.
• Should a vehicle accidentally come in contact with an overhead line, stay
in the cab if the vehicle is not on fire. If there is a danger of fire, you
should jump clear, stay clear and keep everyone else clear until ESB
Networks arrive. On no account should you return to the vehicle.
• It is your responsibility to enure that any machinery or equipment (eg.
ladders, cranes, scaffolding etc.) set up outside the ‘at risk zone’ (see
section 7) is stable and that precautions are put in place to prevent them
from falling into the ‘at risk zone’.
12. Communicating the Safety Message
• ESB Networks advertise regularly on television and newspapers on the
dangers of working near overhead lines in an effort to ensure that
contractors and high machinery operators are fully aware of the hazards.
• In addition to this booklet, a safety poster giving brief details and
illustrations of the precautions required when working near overhead
lines is available from ESB Networks. The poster is entitled
“AVOIDANCE OF ELECTRICAL HAZARDS WHEN WORKING NEAR
OVERHEAD ELECTRIC LINES”

AVOIDANCE OF ELECTRICAL
HAZARDS WHEN WORKING
NEAR OVERHEAD LINES
At the planning stage and before starting
work near an overhead line consult your
local ESB office.
THERE ARE TWO GENERAL CASES
SITE WHERE THERE WILL BE NO WORK OR PASSAGE OF
PLANT UNDER A LIVE OVERHEAD LINE
• A barrier should run parallel to
the line. (See below for distance from line)
• This may be fixed post fencing
or steel drums filled with
rubble spaced 1.5 metres apart.
• If cranes are in use a line of
bunting at a height of 3
metres should supplement the
barriers. (See below for distance from line)
• Danger notice stating “Danger
Live Overhead Line” should be
spaced at intervals.
SITE WHERE PLANT WILL PASS UNDER A LIVE OVERHEAD LINE
• In addition to the above, Goal Posts
should be erected as shown
Dimensions as follows:
Height of goalposts
- As advised by ESB
Width of Goalposts
- Max. 10 metres.
Height of bunting
- 3 metres
Distance between steel drums
- 1.5 metres
Distance between danger notices
- 20 metres
Horizontal distance of barrier to outside conductor on line
- 6 metres minimum for LV, 10kV, 20kV, 38kV.
- 10 metres minimum for 110kV, 220kV, 400kV.
In general if work is to be undertaken directly under the line, ESB
will insist that the line is switched off for the duration of the work.
ESB may permit working under a live line only if special agreed precautions are put in place.
Booklet (ESB Code 9803203) also available which gives greater detail.
