Q.What is the need of doing winding resistance test?
A. For different types of PT 's we have different secondary resistance values which are specified on name plate details.It will mainly depend upon burden to be connected to PT.
Q.Can this test done by multi meter? or should we use any kit?
A. We can do by using multi meter because PT winding resistance is some what higher so multi meter probe resistance will not effect so much.
PROCEDURE:
1. Isolate secondary of PT from any other winding.
2. By using multi meter measure winding resistance.
3. Repeat the same for different taps if it has tappings.
