This document provides an overview of lightning and overvoltage protection devices from Siemens. It discusses the need for such protection to prevent damage to electrical and electronic equipment from transient overvoltages caused by lightning strikes, switching operations, and electrostatic discharges. It then describes different categories of lightning arresters, surge arresters, and surge protection adapters for various installation locations and voltage classes. These provide protection for systems in buildings, industry, offices, households, and for hobbies. The introduction emphasizes the importance of comprehensive protection at all vulnerable interfaces to reliably prevent equipment destruction.
Lightning and Surge Protection Strategy for InstrumentationRekaNext Capital
When Sensors are deployed outdoor, they need to be protected from Lightning voltage Surges. These are basic simple devices used to protect expensive sensors as voltage surges can occur anytime. This increase longivity of sensors and instruments
This is a great guide to surge protection from Hager and if you would like Hager Surge Protection fitted to your Bypass Switches Input for mains one or two please call us on 0800 978 8988 or email sales@criticalpowersupplies.co.uk
Critical Power Supplies provide a range of surge protection kits that can be fitted to any of our bypass switches or consumer units to meet Amendment 1 of the 17th Edition.
The surge protection devices in the kit offer type 2 protection to the BS EN 61643 standard, to ensure conformity with the current edition of BS 7671.
Amendment 1 of the 17th Edition requires electricians to conduct a risk assessment of properties to see if they require surge protection.
When you consider that many homes have a lot of sensitive electronic equipment, such as TVs, Hi-Fis, PCs and printers that would be adversely affected by a voltage surge, then the need for such devices increases.
Transient overvoltages are not just caused by a direct lightning strike, a nearby strike, within a kilometre, can cause substantial damage. Other causes can be fluctuations in the power supply or from equipment such as microwaves or showers being switched.
Our surge protection kit can prevent the spread of overvoltages in electrical installations and protect the equipment connected to it. It is characterised by an 8/20us current wave.

Practical HV and LV Switching Operations and Safety RulesLiving Online
In this workshop, we will take a look at the theoretical aspects of safety as well as the practical and statutory issues. One of the main causes of electrical accidents is said to be incorrect isolation of the circuits where work is to be done. To ensure safety of operators and maintenance personnel, proper switching procedures are necessary and more so when the circuits have multiple feeds and are complex. The possibility of voltage being fed back from secondary circuits needs to be considered as well. This workshop emphasises on the isolation procedures to ensure proper and safe isolation of HV, LV and secondary circuits.
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.

High Voltage Design and Installations Master ClassLiving Online
This course is aimed at the private electrical installation designer. However, the topic HV design and installation could also be interpreted as possibly covering the electricity utility transmission and distribution sector (HV transmission and distribution network design) for which the HV design approach would be quite different, even though the technical fundamentals (and some of the technical standards such as AS 2067) are the same. This will not be the focus of this presentation.

Installing, Programming & Commissioning of Power System Protection Relays and...Living Online
The continuity of the electrical power supply is very important to consumers especially in the industrial sector. Protection relays are used in power systems to maximise continuity of supply and are found in both small and large power systems from generation, through transmission, distribution and utilisation of the power. A good understanding of their application, operation and maintenance is critical for operating and maintenance personnel.
In this workshop, you will gain a thorough understanding of the capabilities of power system protection relays and how they fit into the overall distribution network. The practical sessions covering the calculation of fault currents, selection of appropriate relays and relay coordination as well as hands-on practice in configuring and setting of some of the commonly used types of protection relays used in industry will give you an excellent understanding. Simulation software and real relays (but at safe voltages) will be used to give the participants practical experience in setting up and configuring the various power parameters. Both electro-mechanical and microprocessor relays will be used to demonstrate the key configuration settings required and the major differences in the approach adopted between these two classes of relays.
The strengths and weaknesses of the latest microprocessor (or numerical) relays as compared to the older electromechanical relays will be outlined. You will also gain a solid appreciation of how the modern relay communicates not only to the central SCADA system but also between themselves resulting in a truly multifunctional system which includes protection, control and monitoring. Finally, you will gain a solid understanding of issues of reliability and security for the modern relay.

High current is a hazard to the turbine and technicians alike. For the turbine, lightning strikes can damage blades and short out electric equipment when not sufficiently grounded. There are ways to handle the high current in lightning. Inside the nacelle, technicians have to diagnose issues to get troubled turbines back into production as soon as possible. Several new smart electrical meters can assist that work.
The electrical arc creates a pressure wave. The incident energy is the energy of this arc-flash coming into contact with a surface. Essentially an electric arc creates a radiation burn which accounts for the internal burns a person can receive when exposed to an electrical arc flash.
Practical Arc Flash Protection for Electrical Safety ProfessionalsLiving Online
Electrical safety is an important issue for those working on electrical facilities in utility networks and large industrial installations. A number of serious accidents including fatalities occur every year due to accidents involving electricity resulting in huge financial losses and wasted man-hours. Arc flashes in electrical equipment are now considered one of the major causes of electrical accidents even surpassing the well known hazards of electric shock. Avoiding arc flash incidents and the resulting injuries is one of major challenges today facing electrical workers and requires adequate attention in the stages of system planning, design, installation, operation and maintenance.
Injuries due to arc flash can depend on many factors, one of which is the incident thermal energy on a worker exposed to a flash. Today, a considerable body of knowledge exists as a result of research efforts and is available to designers and maintenance engineers in the form of standards such as IEEE 1584 and NFPA 70E. This workshop will detail the basis of this approach and also about the major advances that have been made in the area of PPE made of FR fabrics and rated for different levels of thermal exposure.
Prevention however still remains the best form of protection and switchgear manufacturers have made considerable design advances to ensure that the effect of arc flash incidents is contained within the enclosure of switchgear (often called arc flash resistant switchgear) and methods of testing such switchgear have also evolved simultaneously. Another important factor is the approach to avoid arc incidents within the switchgear by proper design and maintenance and techniques to reduce the severity of the flash should such incidents occur.
These would form the key focus areas of this workshop.

The basis for intelligent automation is communication. The increasing use of communication makes industry increasingly vulnerable for interference. This EMC lecture gives an insight on the disturbance mechanism based on real industrial cases and provides you solutions.
The ever-increasing use of high-frequency switching devices in industrial automation can result in high-frequency currents circulating in an equipotential bonding network that was not designed for this purpose. The absence of a proven low-impedance bonding network can result in these currents taking alternative and often undesirable routes. Occasionally these will be the shields of industrial network cables such as PROFIBUS and PROFINET that in turn can lead to intermittent communications problems. This presentation will discuss the issues in more detail and will explain the relevance of the recently released PI guidelines “Functional Bonding and Shielding for PROFIBUS and PROFINET”.

■Overview
Introduction to lightning and overvoltage protection
Overvoltage destroys a considerable number of electrical and
electronic devices and units. And the damage is not limited to
just industrial and commercial facilities. Building management
systems as well as household appliances for daily use are also
affected.
Without effective protection against overvoltage there is a real
risk of costly repairs or replacement purchases due to the dam-
age done to equipment.
Listed below are units from various sectors which have sensitive
electronic circuitry and are frequently destroyed by overvoltage.
Clearly, protective measures for preventing overvoltage-related
damage are just as important to private households as for the
commercial and industrial sectors. An effective overvoltage pro-
tection concept for building management systems covers power
supply, telephone, aerial/reception, data processing and control
systems. What is important is that all the cables connected to a
device are linked to a suitable surge arrester. Nearly all devices
have a power supply. A television set, for example, also needs a
reception signal which is supplied over an aerial cable. And re-
gardless of whether the signal comes from an aerial or a wide
band cable, both the aerial input and power supply to the televi-
sion set should be protected. The need for such consistent all-
round protection applies equally to all other devices and units.

In relation to the total value of the equipment concerned, the cost
of installing suitable protective devices usually pays for itself
when just a single unit of electrical equipment is saved just once
from destruction . Provided the performance parameters are not
exceeded, surge suppressors work many times, thus increasing
the benefits for the user several-fold.
The comprehensive surge protection concept
Fundamentals
Transient overvoltage results from lightning discharges, switch-
ing operations in electrical circuits and electrostatic discharges.
Without the protection provided by lightning arresters and over-
voltage protection equipment, even the robustly constructed
low-voltage supply systems of buildings or industrial plants are
unable to cope with a lightning discharge. The overvoltage
occurs only very briefly for millionths of a second. Nevertheless,
the mostly very high voltages involved are capable of destroying
electronic circuitry or the insulation between the conductors on
printed circuit-boards. And even if an electrical or electronic
device has passed the voltage withstand test according to
IEC 100045, as required for being awarded the CE symbol, it is
still not in a position to withstand unscathed all environmental
influences with regard to electromagnetic compatibility (EMC).
To prevent the destruction of electrical equipment by overvolt-
age, all endangered interfaces such as signal inputs and power
supplies must be connected to overvoltage protection equip-
ment. What is needed, depending on the case of application,
are components such as spark gaps, gas-filled surge arresters,
varistors and suppressor diodes, which because of the differ-
ences in their arresting and limiting specifications are arranged
singly or as combinations in a protection circuit.
The following damage can be caused by overvoltage
Overvoltage endangers and destroys a considerable number of
electrical and electronic installations. In the last few years there
has been a sharp increase in the frequency of incidents and the
total costs of the damage incurred. The statistics published by
property insurance companies have a clear tale to tell. Damage
to devices and their destruction occur all the more often when
devices need to be in permanent standby.
Repairs and replacement purchases are not the only expense
factor, however. Costs also arise through not being able to use
the affected system components and possibly even through loss
of software and data. The damage profiles generally cover
everything from destroyed cables, printed circuit-boards and
switching devices to substantial mechanical destruction of the
building installations. This damage can be reliably prevented by
lightning arresters, surge suppressors and arrester combina-
tions.

Lightning and overvoltage protection – WHY?
Powerful information systems form the backbone of our modern
industrial society. A fault or the failure of these types of systems
can have far-reaching consequences. These can even cause
service and industry companies to go bankrupt.
The cause of faults are many and electromagnetic influences
play a major role. In a highly technical, electromagnetic environ-
ment, it is not advisable to simply wait for the mutual influencing
of electrical and electronic devices and systems and then pay
good money to eliminate the resulting problems. Rather it is es-
sential to plan and take preventative measures that reduce the
risk of influences, faults and destruction.
In spite of all this, the damage and loss statistics of electronic in-
surance companies are extremely worrying: More than a quarter
of all claims are as a result of overvoltages due to electromag-
netic influences.
Source: The causes of damage to electronics in 2001, analysis of 7370
claims Württembergische Versicherungs AG.
Causes of overvoltage
Depending on their cause, overvoltages are divided into two cat-
egories:
• LEMP (Lightning ElectroMagnetic Pulse) – overvoltages,
caused by atmospheric influences (e.g. direct lightning
strikes, electromagnetic lightning fields).
• SEMP (Switching ElectroMagnetic Pulse) – overvoltages
caused by switching operations (e.g. disconnection of short-
circuits, normal switching of loads).
Overvoltages that are the result of thunderstorms are caused by
direct/close-up or remote strikes (see diagram on page 5/5).
Direct or close-up strikes are lightning strikes to the lightning
protection system of a building, its immediate proximity or to the
electrical conductive systems of a building (e.g. l.v. power sup-
ply, TC and control lines). The resulting surge currents and volt-
ages are a particular threat to the system to be protected due to
their amplitude and power.
In the case of direct or close-up lightning strikes, the overvoltag-
es (see diagram on page 5/5) are caused by the voltage drop at
the surge grounding resistance and the resulting increase in
potential of the building, compared to the distant environment.
This represents the greatest possible loading of an electrical
plant in buildings.
The characteristic parameters of the surge current (peak value,
rate of current rise, charge content, specific energy) can be de-
scribed using the surge current waveform 10/350 µs (see dia-
gram: examples of impulse test currents). These are defined in
the international, European and national standards as test cur-
rent for components and devices for protection in the event of
direct strikes.
In addition to the voltage drop at the surge grounding resis-
tance, overvoltages also occur in electrical building installations
and the connected systems and devices, due to the induction
effect of the electromagnetic lightning field (see diagram on
page 5/5: Example 1b).
The energy of these induced overvoltages and the resulting
pulse currents is considerably less than that of a direct lightning
impulse current and is therefore only described with surge cur-
rent wave 8/20 µs (see diagram: Examples of impulse test
currents). Components and devices that do not carry currents
from direct lightning strikes are therefore checked using surge
currents 8/20 µs.
Examples of impulse test currents
The protection concept
Remote strikes are lightning strikes at a greater distance from
the objects to be protected, lightning strikes in the medium-
voltage overhead system or the immediate proximity thereof,
or lightning discharges from cloud to cloud (see diagram on
page 5/5: Cases 2a, 2b and 2c). At the same time as these in-
duced overvoltages, the effects of remote strikes on the electri-
cal system of a building are controlled through devices and
components, the dimensions of which correspond to surge cur-
rent wave 8/20 µs.
The causes of overvoltages due to switching operations in-
clude the following:
• Switching off of inductive loads
(e.g. transformers, reactors, motors),
• Ignition and interruption of electric arcs
(e.g. arc-welding device),
• Tripping of fuses.
The effects of switching operations in the electrical installation of
a building are simulated for testing purposes with surge currents
of waveform 8/20 µs.
To ensure the continuous availability of complex power and in-
formation systems, even in the event of direct lightning strikes,
further measures for overvoltage protection of electrical and
electronic systems are required as well as a building lightning
protection system. It is important to take all the causes of over-
voltages into account. For this purpose, the lightning protection
zone concept is used as described in IEC 62305-4
(DIN V VDE V 0185-4) (see diagram on page 5/6). The building
is divided into zones of different danger levels. Using these
zones, it is possible to determine the devices and components
required for the lightning and overvoltage protection.

An EMC-oriented lightning protection zone concept should also
include external lightning protection (with air terminals, arrest-
ers, grounding), equipotential bonding, room insulation and
overvoltage protection for power and information systems.
For the definition of lightning protection zones (LPZ), please use
the specifications made in the table "Definition of lightning
protection zones".
Definition of lightning protection zones
According to the demands and loads made on overvoltage pro-
tection devices with regard to their installation site, these are di-
vided into lightning arresters, surge arresters and arrester com-
binations.
The highest demands with regard to discharge capacity are
made on lightning current and arrester combinations, which im-
plement the transition from lightning protection zone LPZ 0A to
LPZ 1 or LPZ 0A to LPZ 2. These surge arresters must be able to
carry lightning partial currents of waveform 10/350 µs several
times and thus prevent these destructive currents from penetrat-
ing the electrical installation of a building. At the transition of
lightning protection zone LPZ 0B to LPZ 1 the downstream light-
ning arrester at the transition area of lightning protection zones
LPZ 1 auf LPZ 2 and higher, surge arresters are installed to pro-
tect against overvoltages. It is their task to further attenuate the
remaining extent of the upstream protection level and restrict the
overvoltages in the system, whether they are induced or self-
generated.
The lightning and overvoltage protective measures at the bor-
ders of the lightning protection zones apply in equal measure to
the energy and information system. The holistic approach of the
measures described in the EMC-oriented lightning protection
zone concept means it is possible to achieve permanent plant
availability of a modern infrastructure.
Causes for overvoltages during lightning discharges
Lightning
protection
zones
Description
LPZ 0A Zone where objects are exposed to direct lightning strikes
and must therefore carry the whole lightning current. The
undamped electromagnetic field occurs in this case.
LPZ 0B Zone where objects are not exposed to direct lightning
strikes but where the undamped electromagnetic field still
occurs.
LPZ 1 Zone where objects are not exposed to direct lightning
strikes and in which the currents are reduced compared
to Zone 0A. In this zone, the electromagnetic field may be
damped, depending on the insulation measures imple-
mented.
LPZ 2,
LPZ 3
If a significant reduction in the conducted currents and/ or
the electromagnetic field is required, subsequent zones
must be set up. The demand on these zones must be
geared towards the required environment zones of the
system to be protected.

■Benefits
• Type 1 lightning arresters do not require decoupling reactors
to be fitted in the plant. This simplifies plant configuration and
reduces space requirements. No time is wasted on planning
the installation of decoupling reactors. This also considerably
cuts costs.
• The rated arrester voltage is a uniform 350 V AC. This in-
creases safety in systems with extended voltage overshoots.
• All lightning arresters are fitted with a mechanical fault indica-
tion, which does not require an extra power supply. This
means they can be installed in the precounter area, where
electrical plants can be protected particularly effectively.
• The protective modules are plug-in versions. No mounting
work required when replacing the protective modules. When
taking insulation measurements, the protective modules are
simply removed, no need to disconnect the power supply.
• All type 1 lightning arresters are fitted with a remote indication
contact, which is inserted in the device and does not require
any further space. A remote signaling is always possible, even
in the event of a power failure.
■Application
• Type 1 lightning arresters include the system cables in the
equipotential bonding, which protects the low-voltage
systems against the overvoltages and high surge currents that
can be triggered by direct or indirect lightning strikes.
• The protection level is lowered to 1.5 kV by the lightning ar-
rester, which reduces the load on the plant if a lightning strike
is discharged.
• The lightning arresters are enclosed and are suitable for
installation in the precounter area.
• Tested by wave-shaped lightning impulse, 25/100 kA with
waveform 10/350 µs.

■Benefits
• Type 2 surge arresters do not require decoupling reactors to
be fitted in the system. This simplifies plant configuration and
reduces space requirements. No time is wasted on planning
the installation of decoupling reactors. This considerably cuts
costs.
• The rated arrester voltage is a uniform 350 V AC. This
increases safety in systems with extended voltage overshoots.
• All type 2 surge arresters are fitted with a mechanical fault
indication, which does not require an extra power supply.
• The protective modules are plug-in versions. No mounting
work required when replacing the protective modules. When
taking insulation measurements, the protective modules are
simply removed, no need to disconnect the surge arrester
from the power supply.
• The same protective modules are used as for combination
arresters. This simplifies stock-keeping.
• All type 2 surge arresters are available with a remote signaling
contact, which is inserted in the device and does not require
any further space. A remote signaling is always possible, even
in the event of a power failure. The remote signaling signals a
fault even if the protective module is not plugged in.
• The protective module is only 12 mm wide and is an outstand-
ing space-saving solution.
■Application
• Type 2 surge arresters are used after type 1 lightning arresters
in main distribution boards or sub-distribution boards and pro-
tect low-voltage systems against overvoltages.
• The type 2 surge arrester lowers the level of protection to
1.5 kV.
• A thermal isolating arrester disconnector offers a high degree
of protection against overload during runtime.

5/22 Siemens ET B1 T · 2007
■Benefits
• All type 3 surge protection adapters are fitted with an LED as
a visual status and fault indication.
• The protection circuit is continuously thermally monitored. This
ensures constant safe operation for the operator.
• The attractive design fits well into residential living spaces.
■Application
• Type 3 surge protection adapters for insertion in a 5
socket outlet protect electronic loads against overvoltages
from main power supplies.
• However, overvoltages do not just reach loads over power
cables. Telecommunication devices for TAE, ISDN/RDS and
RJ12 connection, televisions or radios with aerial connection
or satellite radio connection are all connected to a further
power supply system which may also pass overvoltages on to
devices.
