anyone has problem-solving experience about autotransformer to start 1750HP motor, I had a problem with the system when I started the test with the main and start system 'the motor system control is working fine but moving from an initial condition to running the draw/starter unit can't work, no there is a reason I have in the protection of the system, I have a control wire and I do not find any other errors, but if I open the motor connection, the controls run normally. I have checked the motor isolation and the results are in good condition
