A transformer is an electrical device that transfers electrical energy from one circuit to another through electromagnetic induction.

• Transformers are used to increase or decrease the voltage of an alternating current (AC) power supply.

• They consist of two coils of wire, known as the primary and secondary coils, which are wrapped around a magnetic core.

• When an AC voltage is applied to the primary coil, it creates a magne...read more

CT stands for Current Transformer and PT stands for Potential Transformer.

• CT is used to measure high current levels by stepping down the current to a lower level.

• PT is used to measure high voltage levels by stepping down the voltage to a lower level.

• Both CT and PT are used in power systems for protection and metering purposes.

• CT and PT are also used in testing and commissioning of power systems.

• Examples of CT and PT in...read more
