Hi,
I have a 3 phase 380V of AC breaker motor part need to be standalone test to make sure this part is still good.






How to standalone test of this AC breaker motor part, is it using insulation check or just resistance check? and what is the good measurement range?
Thanks in advance.

 

If you have a 380v 3ph source, then just place a steel plate over the pole faces, apply the 3ph and measure the current.

Currently I don't have the source, that's why I need to know how to standalone check the part.
