Commissioning and condition assessment of medium voltage cables

The VLF Sine 62 kV, with integrated tan delta, is a compact, robust, and portable high-performance VLF sine wave test system for medium voltage cables.

The 62 kV tester is a multifunctional tool. In addition to VLF and DC testing, it can also perform sheath testing and sheath fault pinpointing when used in combination with the step voltage probe ESG NT/ NT2.

Furthermore, the optional internal tan delta expands the system to assess both cable integrity and condition. The smart VLF system automatically adjusts the test frequency to the cable length, making even tests on 35 kV rated cables (up to 25 km) easy and reliable.

The system can also be used as a voltage source for the optional PD attachment, the PDS 62-SIN. Via this it can be expanded to a universal testing and diagnostic system enabling withstand testing, tan delta diagnosis and partial discharge diagnosis.
