Product Description

AC  high voltage partial discharge  inductive withstand voltage test set hv resonant test system for transformer,gis, or cable
 

I. Summary

Partial discharge Indutive Withstand Voltage Test System  is suitable for the transfer and preventive test of large-capacity, high-voltage capacitive test products. Taking into account a wide range of applications, the principle of series resonance is used to meet the AC resistance test of high-voltage cables and other capacitor-type samples.

The device is mainly composed of partial discharge variable frequency power source, variable frequency control power supply,partial discharge excitation transformer, partial discharge reactor, partial discharge capacitive voltage divider.

It can test in sections, set the first, second, and third stage test voltage, and carry out section tests,,especially suitable for GIS AC withstand voltage test
 

Product nickname: AC resonant test set, hipot tester, HV resonant test set, AC resonant test system supplier

 
II. Resonant test system advantage 
 

1. Device with over-voltage,over-current, zero startup, system detuning,high voltage flashover fault,ect  protection function.the over-voltage over-current protection value can be set according to the needs of user.flashover protection movement when the test object flashover, and mark down flashover voltage value, for test analyzed.

2.The whole device ,the largest piece very light weight not more than 40kg and convenient for field use.

3.Device has four working mode, user-friendly according to the site condition flexible choice, improve test speed.working mode as automatic mode,manual mode,automatic tune mode and manual boost mode.

4.Can store and print data,nonlocal print data, the serial number of the stored data is number, easy to help users digital identification and searching.

5.Frequency starting point can be set arbitrarily within prescribed scope when the device automatic frequency sweep.Sweep frequency direction can choose to up or down,, meanwhile color LCD big screen display scanning resonance boost and timing curve, be convenient for the user intuitive understanding whether find resonant point.

6.Adopted DSP platform technology, according to user needs ,can conveniently increase or decrease function and upgrade, but also makes the man-computer exchange interface humanized.
