Impulse Voltage & Current Generator

Impulse Voltage And Current Testing

Shanghai Jiuzhi Electric Co., Ltd.

Our advanced CDY series Impulse 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 and 60502-1 for cables). By adding extra components, our impulse test system also can generate steeping wave (SWI, >2500kV/ µs) and impulse current (IC, 4/10 µs, 8/20µs, 10/350µs).
