A transformer is a device that transfers electrical energy between two or more circuits through electromagnetic induction.
Consists of two coils of wire, known as primary and secondary coils
Primary coil receives electrical energy and creates a magnetic field
Magnetic field induces a voltage in the secondary coil, transferring energy
Used in power distribution, voltage regulation, and electrical isolation

Switchyard schemes are used to control and protect electrical power systems.
Switchyard schemes are designed to ensure safe and reliable operation of power systems.
They include various components such as circuit breakers, transformers, and protective relays.
Different types of switchyard schemes include single bus, double bus, and ring bus configurations.
Switchyard schemes can be used in both high voltage and low voltage...
Generator protection is a system that ensures the safe and reliable operation of generators.
Generator protection systems monitor and protect generators from overloading, overvoltage, undervoltage, and other faults.
These systems use relays, sensors, and other devices to detect faults and trip the generator if necessary.
Common types of generator protection include overcurrent protection, differential protection, and dist...
