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).

Impulse voltage test systems are available for factory testing from 10 kV to 4800 kV (LI) / 3600 kV (SI), onsite testing from 10 kV to 3000 kV (LI) / 2000kV (SI).

CDY series impulse voltage and current system can be modified for carrying out a variety of special tests, e.g. on transformers, impulse current testing of surge arresters as well as EMP tests of electrical equipment. The chosen modular system enables a very variable application in industries as well in laboratories for research and education.
