VLF Test System 20 kV (SebaKMT)
VLF Test System 20 kV (SebaKMT)
■ The weight of 50 kg make the VLF Test System 20 kV a powerful, universal and at the same time portable unit.
■ The patented change over principle in combination with the recycling of energy stored in the cable capacity results, in comparison to other methods, in a lower weight, less energy consumption and much higher test capacity.
■ The high test capacity of 3 μF permits the simultaneous testing of all three phases.
■ The method is officially recommended by the two VDE Standards 0276-620 and 0276-621.
■ Independent researches shows that VLF test is done most effectively with the 0.1 Hz cosine square wave shape compared to any other VLF wave shape or frequency.
■ VLF is the most economic method for testing PE and
XLPE cables. DC test is not applicable for these cable types.
■ Controlled output voltage
