Substations use various equipment for power distribution and control.
Transformers: Step up or step down voltage levels.
Circuit breakers: Protect the system from overloads and faults.
Switchgear: Control and isolate electrical circuits.
Busbars: Distribute power to different parts of the substation.
Relays: Monitor and protect the system from abnormalities.
Capacitors: Improve power factor and voltage stability.

CTs, PTs, LAs, and Transformers are electrical devices used in power systems for measurement, protection, and voltage transformation.
CTs (Current Transformers) are used to measure and transform high currents into manageable levels for instruments and relays.
PTs (Potential Transformers) are used to measure and transform high voltages into low voltages for instruments and relays.
LAs (Lightning Arresters) are used to prot...
Circuit breakers are safety devices that protect electrical circuits from damage caused by overload, short circuit, or ground fault.
Circuit breakers are used to prevent damage to electrical equipment and wiring.
They interrupt the flow of electricity when there is an overload, short circuit, or ground fault.
Circuit breakers are commonly used in homes, businesses, and industrial settings.
They come in different sizes and ...
The rating of copper and aluminium cables depends on their size, insulation, and intended use.
Copper cables have higher conductivity and are therefore rated higher than aluminium cables of the same size.
The rating of a cable also depends on its insulation material and thickness.
Cables used for high voltage transmission have higher ratings than those used for low voltage applications.
For example, a 10 AWG copper cable m...

Different types of relays are used for protection system such as overcurrent, differential, distance, and directional relays.
Overcurrent relays are used to protect against overloads and short circuits.
Differential relays are used to protect transformers and generators from internal faults.
Distance relays are used to protect transmission lines from faults.
Directional relays are used to protect against faults in specific...

I applied via Walk-in and was interviewed before Apr 2022. There were 3 interview rounds.
The interview question is about 1.33kv&11kv BOQ, power transformer description, and the role of CT/PT.
BOQ for 1.33kv and 11kv involves preparing a bill of quantities for electrical equipment and materials required for the project.
Power transformer description includes its specifications, such as voltage rating, power rating, winding configuration, cooling system, etc.
CT/PT (Current Transformer/Potential Transformer) ar...

The basic concept for construction of a substation involves site selection, design, equipment installation, and commissioning.
Site selection involves identifying a suitable location for the substation based on factors such as proximity to power sources and load centers.
Design involves creating a plan for the substation layout, including the placement of equipment such as transformers, switchgear, and control systems.
