Q.Surge absorbers are used for protection against

  • AHigh voltage low frequency oscillations 
  • BHigh voltage high frequency oscillations
  • CLow voltage high frequency oscillations
  • DLow voltage low frequency oscillations
Correct Answer : (C)

Low voltage high frequency oscillations

Hints :

Surge Absorbers:

  • A surge absorber is a protective device that absorbs the high voltage surges and reduces the steepness of the surge wave fronts. It is also called called Surge Protective Devices (SPD).
  • Surge absorbers are used for protection against Low voltage high frequency oscillations.
