Series Variable Frequency Resonance Ac Hipot Test Equipment ac resonant test system

resonant test for cables Overview

The device is mainly designed for AC voltage test of 110kV cable and 220kV power system. The separate manufacturing reactor design, can meet the requirements of high voltage equipment, test conditions. The small current is, city, county departments and high voltage test of electrical installation, repair and test pressure equipment engineering unit ideal. The device is mainly composed of variable frequency control of the power supply, excitation transformer, high voltage reactor and capacitor divider.
