Versatility in electrical tests

Our high-voltage sources are applicable to a variety of typical tests, including nominal voltage withstand at industrial frequency, breakdown voltage, radio interference voltage, or partial discharges, according to IEC 60060-1 and NBR 6936 standards. For medium-voltage cables, we offer specific solutions such as Very Low Frequency (VLF) sources or resonant sources, meeting standards like IEC 60502-2, CENELEC HD 620 and 621, DIN VDE 0276-620 and 621, and IEEE Std. 400.
