High pot testing
WebHigh potential (HiPOT) testing is an electrostatic stress test that detects potential dielectric failures. It can be conducted as an AC voltage test or DC voltage test depending upon the type of power on which the PCB works. Quality PCB design begins with the selection of appropriate PCB materials WebApr 8, 2008 · When testing Hi-Voltage cable, the high potential is gradually applied over a period of about 15 minutes minutes, with readings taken at the 1 minute intervals. The reading are the cable leakage current in micro-amps. The maximum applied test voltage is 300 volts per mil of insulation.

WebHipot Testing Low, Medium, and High Voltage Motors. For low voltage motors, the DC hipot test is normally a 1-minute test at a specified DC voltage that is higher than the peak lead to lead operating voltage. The test is referred to as an over-voltage test since the voltage is higher than what the motor normally sees.
