SKU: VLF Test System 60 HP

Test with 3 Uo for 36 kV cables especially suited for long cables and offshore installations.

The SEBA VLF tester 0.1 Hz test system with energy recovery for testing of cables with Cosine Rectangular Wave voltage according to VDE, IEC and IEEE standards.

Test with 3 Uo for 36 kV cables especially suited for long cables and offshore installations.

The SEBA VLF tester 0.1 Hz test system with energy recovery for testing of cables with Cosine Rectangular Wave voltage according to VDE, IEC and IEEE standards.

This 60 kV VLF tester can be used to test cables with operating voltage levels up to 36 kV. The system is made up of a control unit and a High Voltage unit. Its high test capacity of 6.5 μF allows for the testing of all three phases to be carried out at the same time. Positive and negative DC testing can also be carried out on cables and connected switchgear using the DC mode.

The systems Cosine Rectangular Wave form voltage of 0.1 Hz ensures that any weak spots in the cable can be broken down. Extensive scientific research as well as practical field tests have been carried out on the VLF method and have proven the advantages of the0.1 Hz Cosine Rectangular Wave Voltage according to IEC HD 620 and 621, the VDE as well as by the IEEE standards.

This 60 kV VLF tester can be used as a stand-alone unit or can be integrated as part of a test van system. The built in safety system and advanced breakdown recognition guarantee maximum safety.

The leakage current measurement on this system enables qualitative assessment of the cable while it also includes a protocolling function which permits the printing and storage of the test data for future reference or reporting.
