Discuss Star delta testing help needed in the Industrial Electrician Talk area at ElectriciansForums.net
Hi,depending on constraints,if it was the motor i was wanting to test,i would not include the wiring from panel to motor. Check as described,but at disconnected motor.
This way,any troubling readings are the motor,and not any included part of the connections.
No such animal as a Star Delta Motor, it's the method of starting that Star Deltahttps://www.youtube.com/watch?v=KsS1v_i2YtUHi I need some help I haven't work on star delta motors since my 1st year apprenticeship. How do you test the motor from the panel i.e check that the windings are balanced?
Any help much appreciated

Best way to check the Windings would be to disconnect the 6 leads at the Motor terminal box, make sure you mark the leads, to avoid malfunctions
Won't be the starter , most likely bearing gone , damaged fan or belt too tight .
if my thinking right the current (in star) of each phase runs across two sets of wiring doubling the resistance and reducing the current therefore why would it be getting hotHow can you say it's not the starter? I have seen motors that have been stuck in star either because of a failed timer or even a welded star contactor and boy does the motor run hot!

Fair enough it's still not the starter
