Test with 3 Uo for 36 kV cables specially suited for long cables and offshore installations.
The powerful 0.1 Hz VLF test system with energy recovery for testing of cables with Cosine Rectangular Wave voltage according to VDE, IEC and IEEE.
The Seba KMT VLF Test System 60 kV can be used to test cables with operating voltage levels up to 36 kV. The system is comprised of a control unit and a HV unit. The high test capacity of 6.5 μF allows for the simultaneous testing of all three phases. Positive and negative DC testing of cables and connected switchgear can be carried by DC Mode.
The 0.1 Hz Cosine Rectangular Wave form voltage ensures that weak spots in the cable are brought to a break-down. 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 harmonisation document IEC HD 620 and 621, the VDE as well as by the IEEE.
This VLF Test System 60 kV can be used as a stand-alone system or as integrated part of a test van system. The built in safety system and advanced breakdown recognition guarantee maximum safety.
Furthermore the leakage current measurement enables qualitative assessment of the cable and the protocolling function permits the printing and storage of the test data for further reporting purposes.
Seba KMT VLF Test System 60 HP Features include:
- Very high test power without frequency reduction
- Covers cables up to 20 km @ maximum Voltage
- No polarisation effects as with DC
- Breakdown detection
- Leakage current measurement
