Power System

Figure 1: Single Line to Ground Fault.

An equation relating the relative motion of the rotor axis with respect to stator field in time domain is known

In the gas turbine power plant, electrical energy generation takes place by using gas turbine as the prime mover.

The electrical load may be defined as the consumption of active and reactive power by an electrical appliance to utilize

Interchanging the positions of conductors at regular intervals along the line so that each conductor occupies another conductor’s position at

The relay which operates based on the frequency and produces a tripping signal when the magnitude of frequency drops below

The transformer is heart of power system. Power transformer is a major equipment in power system. It requires highly reliable protective

Earthing Switch is connected between the line conductor and the earth. Normally, it is open when isolation work of opening

Reactance relay is over current relay with directional restraint. The current polarizing flux goes from upper polarizing coil magnet to lower electromagnet through

The impedance relay is not normally used because of need of a separate directional unit. So mho type relays are
