Electrical rooms provide safe and secure spaces for the operation and maintenance of electrical equipment. While electrical equipment types and ratings can have significant impacts on electrical room requirements, distributing the electrical power to the rest of the building via wiring, busways, and raceways can also affect electrical room design.
Switchboards, switchgear, transformers, generators, and UPSs require space for installation, maintenance, heat dissipation, and possible future expansion. And the wiring, busways, and raceways that distribute the electrical power must be accounted for—now, and in the future. Documentation and monitoring of electrical system’s equipment and how it connects to the rest of the facility must be accurately maintained.
The design of electrical rooms requires an integrated approach among disciplines. Architects and structural, mechanical, and fire protection engineers should work as a team in designing these rooms. NFPA 70: National Electrical Code (NEC) is the main source for electrical room requirements, but other codes, good practices, and recommendations should be considered. The result will be a room that is safe and secure, and provides for the functional operation and maintenance of the specific electrical equipment located within.
Industrial monitoring and control systems using andriod applicationAvinash Vemula
Automation takes the complete control of total plants few authentication and manual actions are needed from user side for completing action .Hence there is a must situation for users presence at all times in the control for taking some timely needed control actions. The proposed system provides a good solution to this problem. The whole control room environment is additionally implemented in the arm-android platform and the same is communicated to the process through Bluetooth. Now the user in control can use mobile at anytime, anywhere to monitor and control the whole plant.8051 is used here for acquiring process control parameters from the sensors like temperature, gas etc and transmitting it via a Bluetooth module to an android device. Hence the parameter values can be monitored and stored simultaneously.

Electrical Substations and Switchyard DesignLiving Online
Electrical substations form important nodal points in all power networks. Substations can be of various capacities, voltages, configurations and types depending on what is the application for which the substation is being designed. Location and layout of a substation present a number of challenges to the designer due to a large variety of options available to a designer. There are ever so many constraints too that need to be kept in mind; technical, environmental and naturally financial. Arriving at an optimum design within these constraints is as much an art as it is a science. Designing a substation which will operate with utmost reliability for at the least three or four decades involves a thorough knowledge of the current state-of-the art equipment, emerging technologies, the tools for presenting and evaluating all available options and a good appreciation of power system operation and maintenance. This course will present a comprehensive capsule of all the knowledge essential for a substation designer and walk the participants through the substation design process using a set of interlinked case studies.
WHO SHOULD ATTEND?
This course is aimed at engineers who are already working as electrical system designers as well as those who belong to any of the fields listed below and wish to prepare themselves for moving into the role of a substation designer.
Utility engineers dealing with power transmission and distribution systems
Electrical engineers involved in power generating plants with utility scale generators
Electrical engineers in large industries who are associated with power distribution
Consulting engineers involved in design of substations
Contractors executing projects involving electrical HV substations
Electrical commissioning engineers

3. WHAT IS A GRID STATION?
• An electrical grid is an interconnected
network for delivering electricity from
suppliers to consumers. It consists of
generating stations that produce
electrical power, high-voltage
transmission lines that carry power from
distant sources to demand centers, and
distribution lines that connect individual
customers.
4. Grid Station Functions
• Voltage Regulation
• Voltage Transformation
• Measure Electrical Power Quantity
• Connect Electrical power generating Plants to the system
• Control Of active and reactive and reactive power
5. LOCATION SELECTION
• Economic and Technical Feasibility
• Load point & requirement
• Bearable Cost (development, Site distance from existing network, misc.
cost)
• Area Required
• Transmission line feasibility
• Near-by Grid Capacity
• Transport Network
6. TYPES OF GRID STATION LAYOUTS
• AIR INSULATED SUB-STATION LAYOUT
• GAS INSULATED SUB-STATION LAYOUT
• HYBRID INSULATED SUB-STATION LAYOUT
12. Power Transformer
• This is the most important component of a sub-
station.
• The main work of a Grid is to distribute power at a low
voltage, by stepping down the voltage that it receives
in its incoming lines.
• The Grid use step-down transformers to attain this
voltage and then distribute this power.
• All the other equipment in a sub-station works only to
facilitate the smooth working of the power
transformer.
13. SWITCHGEAR
• The term switchgear refers to the combination of electrical
disconnects, fuses and/or circuit breakers used to isolate electrical
equipment.
• Switchgear is used both to de-energize equipment to allow work to be
done and to clear faults downstream.
• The very earliest central power stations used simple open knife
switches, mounted on insulating panels of marble or asbestos.
14. Switch Gears Components
• Bus Bars
• Circuit Breakers
• Disconnecting Switches
• Earthing Switches
• Current Transformer
• Potential Transformer
• Cable and box
15.
16. 11 KV Switch gears
• Operated at 12 KV
• Work at 630 A
• Load break switch
• Earthing switch
• O/C and E/F Self powered relay
17. Power line carrier communication
Need of PLCC
• PLCC uses the same high voltage transmission
line connecting two substations for
Telecommunication purpose.
• PLCC is used in all power utilities as a primary
communication service to transmit speech,
• Telemetry and protection tripping commands. This
economic and reliable for inter grid message as
well as low bit RTU signal
• Avoid dependence of busy telephone lines.
• To cope up with ever increasing size of power
grid
18. Power line carrier communication
• Voice signal modulated on carrier frequency and transmitted on
power line
• No need for lying separate cable for transmission
• Integrates transmission of voice and data through same line
• Allows flow of information through same cording which supplies
electrical power.
20. SERGI Transformer Protection
• This transformer protection concept can be applied to all oil-
filled transformers. It serves to:
• Depressurize tanks within milliseconds
• Avoid contact between air (Oxygen) and the evacuated
explosive gases (Hydrogen, Acetylene, etc.)
• Separate gases from the oil
• Channel the flammable gases away from the
transformer to a remote area
• Evacuate the explosive gases from the transformer
tank by injecting an inert gas (Nitrogen) into the tank
and associated equipment
• Secure the transformer to let the maintenance staff to
quickly repair safely.
21. FACILITY LAYOUT
The objective of plant layout planning is a more effective
work flow at the facility, allowing workers and equipment
being more productive
OBJECTIVES OF LAYOUT
1. Sense of unity
2. Safety
3. Flexibility
4. Minimum movement of people material & resources
22. GRID STATION LAYOUT
• Product-oriented layout: Seeks the best personnel and machine
utilizations in repetitive or continuous production: GRID STATION
DISADVANTAGES
1. High volume is required
2. Work stoppage at any point ties up the whole operation
3. Lack of flexibility in product or production rates

37. FIRE STRATEGY
FIRE ESCAPE
• Evacuation in case of fire is a major concern and therefore the layout keeps in its
mind fire exits
• There are normal stairs that can be used as well as emergency exits has been provided
38. CALCULATION
• MAXIMUM OCCUPANTS IN GRID STATION
Max population=40ft*141ft/100sqft per person=56.4=56 people
• MINIMUM NUMBER OF EXITS=2 from below table
The distance between exits
= diagnol /8=146/8=18ft
