Powerful 0.1 Hz VLF test system with energy recovery for testing of cables with Cosine Rectangular wave voltage according to VDE and IEC.

In accordance with most regulations, cables and joints must be tested after installation or repair. The SebaKMT VLF Test System CR 80 kV can be used to test cables with operating voltage levels up to 46 kV. The system consists of a control unit and a HV unit. The high test capacity of 2.5 µF permits simultaneous testing of all three phases. Positive and negative DC testing of cables and connected switchgear can be carried out by switching over to DC Mode.

The advantages of the VLF method with 0.1 Hz Cosine Rectangular wave voltage have been proved by extensive scientific research as well as practical field tests. The method is recommended in the VDE, the harmonisation document IEC HD 620 and 621 as well as by the IEEE 400.

This VLF Test System CR 80 kV can be used as stand-alone system or as a fully integrated part of a test and fault location system.

Key Benefits:

High test power without frequency reduction
No polarisation effects as by DC testing
Protocoling
Breakdown recognition
Leakage current measurement
