Power frequency withstand voltage test electrical equipment insulation resistance power frequency voltage ability ac electric motor test. Test, the sample (s) will be connected to the test loop by the regulation, gradually increase the voltage to the rated power frequency withstand voltage value of the standard, keep 1 min, then quickly and evenly dropping to zero. Within the prescribed period of time, the sample (s) by insulation breakdown or not surface flashover, argues that passed the test. Power frequency ac acmotor2.blogspot.com withstand voltage test on the voltage higher than the rated working voltage electric equipment, can be found through the test many insulation defects, especially for local defect is more electric generator effective, its disadvantage is that may bring insulation must be damage during pressure test, so should be in the insulation resistance, dielectric loss factor test, power frequency ac withstand voltage test can be performed.
