The induction type over current relay used to detect the over current fault in electrical power system. The over current relay operates when
Lightning arrestor is also known as surge diverter. Lightning arrestors protect system equipment from the high transient voltage which is
Power factor is a ratio of true power over apparent power. Power factor also known as cosine of angle between voltage and current in A.C. System.
Overhead insulator are the insulator which are used in overhead transmission line to prevent unwanted flow of electric current.
