WebJan 1, 1996 · For preventative maintenance, the motor winding should be cleaned, treated, and dried to restore winding flexibility. 3) Step voltage test. This test is particularly useful in evaluating aged or damaged insulation not necessarily having moisture or contamination. A dual voltage test instrument is required here. WebContinuity testing tests the resistance between two points. If there is low resistance, the two points are electrically connected. If there is higher resistance, the circuit is open. The earth continuity test determines whether the motor is connected to ground. To complete the earth continuity test, set the multimeter to continuity mode.
