Huazheng Electric Manufacturing HVAC Frequency Series Resonant Test Set

The device is designed and manufactured mainly for AC voltage withstand test of main electrical equipment, such as 10kV and 35kV cable, electric generator and main transformer of 220kV and below. Electric reactor is designed separately with multiple sections, and the various combinations of series/parallel connections could increase or decrease voltage, electric current, frequency, power, and so on. For example, series connection could boost voltage and frequency, and parallel connection could increase electric current and reduce frequency. The device is applied widely to high-voltage testing departments of city and county, and is the ideal withstand voltage equipment for companies engaged in power installation and maintenance.

The device is mainly consisted of variable-frequency power source, Excitation transformer, electric reactor, capacitive voltage divider, and so on.
