Electrical Site Supervisor Interview Questions and Answers

CT and PT are essential components in a substation for measuring and protecting electrical systems.

• CT (Current Transformer) is used to measure current in the circuit and step down the current to a safe level for measurement.

• PT (Potential Transformer) is used to measure voltage in the circuit and step down the voltage to a safe level for measurement.

• CTs and PTs are used in conjunction with relays for protection of electrical systems in the substation.

• CTs and PTs are calibrated...read more

A transformer is a device that transfers electrical energy between two or more circuits through electromagnetic induction, while a power transformer is specifically designed to handle high power levels.

• Transformers transfer electrical energy between circuits through electromagnetic induction

• Power transformers are designed to handle high power levels

• Power transformers are typically used in power distribution systems to step up or step down voltage levels

• Transformers can be use...read more

33/11 kv line and AB cable with TR installed

• This question seems to be related to electrical engineering

• 33/11 kv line refers to a power transmission line with a voltage of 33 kV and 11 kV

• AB cable is a type of insulated cable used for power distribution

• TR stands for transformer, which is used to step up or step down voltage levels

• The installation of a transformer on a power line can help regulate voltage levels and improve efficiency
