Have a customer with a farm with numerous motors from 5hp thru 50hp for for conveyors and bin dryers etc. Customer recently changed out a 25hp motor and when done noticed that on the control panel one phase for motor was drawing half of full load while the other legs were showing full load. Upon our checking we found that all the motors were doing the same thing. (One leg at half current of full load) This is a 240 volt open delta service.
Had the power company out, they replaced one transformer, said everything was fine, all voltages between phases are normal but still the one leg of all motors is still off.
Any thoughts would be appreciated.
