Which instrument is used for conducting tests after wire installation?...
After completion of the wire installation, we do the following test:
(1) Polarity Test:
- In this test If the switch is inserted in the live line, the megger will indicate ‘zero’ reading.
- On the other hand, if the pointer of the megger shows ‘infinity’ or any high value of resistance, it may be concluded that the switch has not been inserted in the live wire; it has been placed in the neutral or some other wire
(2) To Test the Effectiveness of Earth resistance:
In megger, the arrangement is such that when the handle of the instrument is turned, alternating current flows through the earth, but direct current flows through the device for measuring the earth resistance.
As both of these tests is performed by using Megger only. So, megger is the correct option.
