Q2. Tell me about types of instrument transformer
Ans. 
Instrument transformers are used to measure high voltage and current levels. There are two types: current transformers and voltage transformers.
• Current transformers (CTs) are used to measure high current levels and step down the current to a lower level that can be measured by a meter or relay.

• Voltage transformers (VTs) are used to measure high voltage levels and step down the voltage to a lower level that can be measu...read more

Q1. What is transformer and it's working
Ans. 
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 work on the principle of electromagnetic induction, where a changing magnetic field induces a voltage in a coil of wire.

• Transformers have two coils of wire, a primary coil and a seco...read more
