Question

1 ) in the cables the location of fault is usually found out by compering....

(a) the resistance of the conductor
(b)the inductance of conductors
(c) the capacitance of insulated conductors
(d) all above parameters​

Answer 1

Answer:

option (c)

Explanation:

To find the location of cable fault using the thumping method, a thumper is set to thump repeatedly and then walking along the cable route to hear the thumping sound. The higher the dc voltage applied, the louder will be the resulting thump. This method is useful for relatively shorter cables.
