Which device protects the high voltage surges on the power system?

Which device protects the high voltage surges on the power system? Correct Answer Lightning arrester

Lightning arrester:

  • The device which is used for the protection of the equipment at the substations against travelling waves, such type of device is called lightning arrester or surge diverter
  • It diverts the abnormal high voltage to the ground without affecting the continuity of supply
  • It is connected between the line and earth, i.e., in parallel with the equipment to be protected at the substation

 

Characteristics are shown below.
