Product description:

Impulse voltage test systems

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) .

E type V type H type
up to: 1800 kV up to: 4800 kV up to: 7200 kV
up to: 180 kJ up to: 600 kJ up to: 1620 kJ
