Good suggestion!Possible just conceal some appropriate value resistors on the back of the motor terminal plates, to give the readings you want?
Or simply connect them on the terminals in the motor junction box, and bring flying leads out terminal strips for 'easy connection' of the megger?
That way you could easily simulate earth leakage, a partial short between phases on a 3 phase motor or a high resistance phase, all with no permanent damage to the motors.
