What is the work of sub station attendant?
Job DescriptionSubstation attendant maintains all indoor and outdoor equipment in good operating condition. He prepares daily log sheet on an hourly basis to note down all electrical parameters, energy readings, etc.
What does a substation operator do?
As a substation operator, it is your job to run and manage an electrical substation so that customers can safely use electricity. Your job duties are to inspect, maintain, and monitor all equipment, including power converters, circuit breakers, and voltage transformers.
Who works on a substation?
A substation electrician is a highly skilled professional responsible for inspecting, maintaining, and repairing substation electrical equipment. The common types of equipment they work with include oil circuit breakers, transformers, and insulators.
What are the equipment used in substation?
The following equipment are installed in distribution substations:
- Distribution Transformer.
- Circuit breaker.
- Lightning Arrester.
- Air Break (AB) switches / Isolator.
- Insulator.
- Busbar.
- Capacitor Bank.
- Earthing.
Why is DC supply used in substations?
The main reason for using DC supply in substation or power stations is to provide a continuous power supply to the control circuit. DC is a reliable source of power supply because it can obtain from batteries. So during power failure also, we have to provide the continuous power supply to the control circuit.
What are the main components of a sub station?
Elements of a substation
- Primary power lines.
- Ground wire.
- Overhead lines.
- Transformer for measurement of electric voltage.
- Disconnect switch.
- Circuit breaker.
- Current transformer.
- Lightning arrester.
What is substation capacity?
Substation credible capacity refers to the capacity of the GPS to supply the distribution network that is equivalent at the high voltage distribution network level when considering the faults of the main transformer, 110 kV lines, and circuit breakers.
What is the difference between 33kV and 11kV?
The 11kV lines are used in residential areas and is what feeds the local transformers, which then distributes power to the buildings in the area. 33kV lines on the other hand involve much higher voltages and are used to distribute power from one small sub-station to another.
