Series Resonance Withstand Voltage Equipment

Series resonance withstand voltage equipment adopts the method of adjusting the frequency of the power supply, so that the reactor and the tested capacitor achieve resonance, obtaining high voltage and large current on the tested object. It is a new method and trend in high-voltage testing, and has been widely applied both domestically and internationally.



Series resonance withstand voltage equipment consists of a frequency-modulated and voltage-regulated power supply, an excitation transformer, a reactor, and a capacitive voltage divider.

Product Characteristics





  • 1. Cables with voltage levels of 35kV and below are used in large quantities, and the test workload is heavy. Therefore, this type of withstand voltage test device is small in size and light in weight, giving rise to the portable cable withstand voltage test system.




  • 2. This system requires that the weight of components that can be moved by a single person on site does not exceed 30kg, and the weight of components that can be moved by two people on site does not exceed 60kg, suitable for on-site handling.




  • 3. The power supply adopts 220V single-phase or 380V single power supply, convenient for on-site power access.




  • 4. The reactor part adopts dry-type epoxy casting, which is beautiful and reliable, suitable for various cable requirements.




  • 5. For cable withstand voltage tests of 110kV and above, oil-immersed reactors are used. When the single component weight exceeds 100kg, our company's special small electric hoist can be optionally equipped
