IR TESTING DELTA CONNECTED MOTOR
IR TESTING DELTA CONNECTED MOTOR
(OP)
Hi all,
Can someone please state the correct method to adopt in testing a delta connected 3 phase motors insulation resistance, & how it differs from testing a star connected 3 phase motor. We are having a dispute on the matter & an un-baised opinion would settle the argument.
Many thanks.

What is the difference that is suggested?

(2B)+(2B)' ?
RE: IR TESTING DELTA CONNECTED MOTOR
The dispute was over how you complete an IR test, as stated it's identical for both Wye/delta. The opposing argument was that the delta configuration when tested needs splitting, not true as a low IR will be indicated regardless of doing so, only at the point of having established a low IR/if it were deemend necessary to prove which phase was dragging the IR down would it need splitting.
