I have a 460volt 3ph 1hp motor that I need to megger. Traditionaly I place the red lead of the megger to each lead one at a time and the black to motor ground. I check for insulation value of 2megs or better to pass. Can you combine the three motor leads to the red megger lead and place the black to ground to test the motor for shorts?
Are there any other test that I can perform with the megger to evaluate the running condition of the motor.
