VCB, SF6, CT, PT, LA are all electrical equipment used in power systems.
VCB stands for Vacuum Circuit Breaker and is used for switching and protection of electrical power systems.
SF6 is a gas used as an insulating medium in high voltage electrical equipment such as circuit breakers, switchgear, and transformers.
CT stands for Current Transformer and is used to measure electrical current in power systems.
PT stands for Po...
Copper and aluminum are commonly used conductors in transmission.
Copper is an excellent conductor due to its high electrical conductivity.
Aluminum is also widely used as it is lightweight and cost-effective.
Other conductors like silver and gold are rarely used due to their high cost.
Copper-clad steel conductors are used in specific applications where strength is required.
Different types of tests related to transformers include routine tests, type tests, and special tests.
Routine tests are performed on every transformer and include measurement of winding resistance, insulation resistance, and voltage ratio.
Type tests are performed on a sample transformer to verify its design and include temperature rise test, impulse test, and short-circuit test.
Special tests are performed on transforme...
Different types of faults refer to the various abnormalities that can occur in an electrical system.
Short circuit fault
Open circuit fault
Ground fault
Overvoltage fault
Undervoltage fault
Overcurrent fault
Undercurrent fault
Relays are switches that open and close circuits electromechanically or electronically. There are various types of relays.
Electromechanical relays
Solid-state relays
Reed relays
Polarized relays
Time-delay relays
Overload protection relays

Transformers are electrical devices that transfer electrical energy between two or more circuits through electromagnetic induction.
Transformers are used to step up or step down voltage levels in electrical power transmission and distribution systems.
They consist of two or more coils of wire, known as windings, that are wound around a core made of magnetic material.
The primary winding is connected to the input voltage s...
I applied via Walk-in and was interviewed before Sep 2022. There were 3 interview rounds.
Power generation equipment includes generators, turbines, and transformers for producing electricity.
Generators convert mechanical energy into electrical energy
Turbines use steam, water, or wind to rotate a shaft connected to a generator
Transformers increase or decrease voltage for efficient transmission and distribution
Examples: gas turbines, hydroelectric generators, step-up transformers
Power formula: P = V x I, Transformer capacity/amp formula: Capacity = V x I, where V is voltage and I is current.
Power formula: P = V x I (P = power, V = voltage, I = current)
Transformer capacity formula: Capacity = V x I (Capacity = transformer capacity, V = voltage, I = current)
