300kV 15kJ Impulse Voltage Generator with multiple chopping device

CJDY Series Impulse voltage test systems are used for impulse voltage testing of transformers, cables, gas-insulated switchgears (GIS), arresters, and other high-voltage devices. The test systems generate lightning impulse voltage (LI, 1.2/50 µs), chopping lightning impulse voltages (LIC, front time 1.2 µs, front, crest or tail chopped), and switching impulse voltage (SI, 250/2500 µs) in accordance with IEC 60060-1; as well as IEC 60076-3 for transformers, and IEC 62067, 60840 und 60502-1 for cables).

Impulse voltage test systems are available for factory testing in three product lines (E, V, and H).
