Can anyone tell me of a simple test to find whether a 3 phase generator (motor) is connected in star or delta?
I have access to the 3 connections to it but not the motor itself as it is in a windmill and it is at the top of a 15m high pole.
I am asking as the windmill in question does not produce as much power as another next to it.
Both 6 kW windmills are controlled by inverters which I think only monitor the rectified DC voltage (~400V) output from the windmill so their output power will be very different depending on their connection type (star or delta).
