Question

in case of earth fault in any electrical circuit, the megger will indicate
a) zero
b) 50M ohm
c) infinity
d) 1M ohm​

Answer 1

Answer:

In case of earth fault in any electrical circuit, the megger will indicate Zero.

Explanation:

An Earth fault is a type of failure in which unintended connection in circuits conductors of power occur in earth.

This fault or failure can be considered as short circuit.

In this case power returns to the equipment from earth and damages the equipment.

Answer 2

The megger in the case of fault in the earth wire of the electrical circuit shows the indication towards zero.

Answer: Option A, Zero

Explanation:

The fault in the earth wire is the fault which occurs in the cases like of short circuit. The power of the electrical circuit dissipating into the earth in normal functioning circuit, changes and the power starts to dissipate to the equipment itself, and thus, the electrical instrument gets damaged.
