DC hipot tester adopts a high-frequency voltage doubling circuit, using the latest PWM pulse width modulation technology and the voltage and current double closed-loop feedback technology to improve the power supply adjustment rate and load regulation rate, making voltage more stable and ripple smaller. Using imported high-power IGBT devices and their driving technology to eliminate the interference of the switch. According to EMI electromagnetic interference and EMC electromagnetic compatibility theory, shielding, isolation, and grounding measures are adopted to improve the safety of the whole machine, and can withstand rated voltage discharge without damage. The selection of imported high-frequency high-voltage rectifier diodes makes the cylinder more compact and lightweight, to enhance the efficiency of the whole machine.
The Instrument protection function is complete, with zero protection, over-voltage protection, overcurrent protection, breakdown protection, protection circuit selection of nanosecond special sensor, and quick and reliable action, effectively protecting the safety of personnel and equipment. Add intelligent high-precision 0.75U1mA function button, which is conducive to the test of zinc oxide arrester

What is a DC hipot test?
Hipot tests are used for everything from very low-voltage devices to high-voltage equipment. For medium to high-voltage rotating equipment, DC hipot tests called step voltage or ramp tests are used to see whether the start of an insulation breakdown can be detected
Â
What is the difference between AC and DC hipot?
DC hi-pot tester provides a more accurate reading of the leakage current as it only reads real current. AC hipot tester, on the other hand, measures total current and does not provide accurate leakage current measurement.
Â
What is the leakage current for DC hipot?
The test waveform, whether DC or an ac sine wave is also typically specified. What constitutes a failure? Hipot test failure is when the leakage current exceeds a specified limit or rapidly increases in an uncontrolled manner, or if arcing is observed. Typical leakage current limits range from 0.5 to 20 mA.
