WebOct 31, 2024 · Because the insulation resistance and reactance of the stray capacitance is so high, the ac test current can be simplified to the leakage current at 250 V times the ratio of hi-pot test voltage to 250 V. If the test voltage is 3000, then the test current would be 3000/250 x 0.5 or 6 mA. WebWhen problems occur in medium and high voltage electric equipment, such as partial discharge and corona, it will produce sound waves that can be detected by Ultrasonic Testing. ... Testing was developed in the early 1980s as a substitute for DC Hipot testing. DC Hipot testing is no longer an acceptable test method for field aged extruded cables ...

WebJul 31, 2024 · Why is the test voltage so high, i.e., more than 10 times the rated input voltage? Electric current in an inductor creates a magnetic field. When the current is switched off, the magnetic field collapses, generating a current in the opposite direction. This current can generate a very high voltage impulse into the power distribution system. WebFeb 24, 2016 · High voltage vs. hipot.
