  1. For effective use of a counterpoise wire
    1. its leakage resistance should be greater than the surge impedance
    2. its leakage resistance should be less than the surge impedance
    3. its leakage resistance should be equal to the surge impedance
    4. two resistance may have any relation
Correct Option: B

If surge impedance will be smaller than the leakage resistance, then positive reflections will occur and the potential of the tower will be raised which will result in flash over of the insulator discs and finally a line-to-ground fault will occur.
