An individual test system is designed for tests of up to 260 kV and 83 A, which facilitates testing of high-voltage cables that can be several kilometers in length. Several test systems can be conveniently connected in series when higher test voltages are required or in parallel when testing cables of up to 100 kilometers in length. These systems can even be used to test ultra-long submarine cables that connect offshore wind farms. The test system has been mounted on a standard-sized trailer, which facilitates transport to the specific site. The test system can be set up on-site within an hour without cranes or similar equipment.
Application
On-site testing of XLPE terrestrial and submarine cables
Withstand voltage testing
Partial discharge measurements (primarily in cable sleeves or short cables)
Benefits
Pure sinusoidal voltage at the output
Low PD background noise level < 10 pC
IEC-compliant frequency range from 20 Hz to 300 Hz
Several systems can be connected in series or parallel to increase test voltage and/or power.
Quick and easy setup of test system
Maintenance-free, no moving parts
