VLF CR-60-HP test system High-performance VLF test system for 36 kV rated cables
■This high-performanee 0.1 Hz VLF test system for cables with cosine-rectangular voltages works in accordance with VDE, IEC and lEEE-standards.
■According to most standards and regulations cable circuits must be tested after installation, after repair or for mainte-nance purposes. The VLF CR-60-HP test system can be used to test cables with operating voltage levels up to 36 kV. The system consists of a control unit and an HV unit The high test capacity of 6.5 μF allows to simultaneously test all three phases with a standardized 0.1 Hz test frequency. Positive and negative DC testing of cables and connected switchgears can be carried out by switching to DC Mode. Aside from cable and sheath testing, the system can also be used to precisely pinpoint sheath faults (in combination with a step voltage probe like the ESG NT).
■Using 0.1 Hz cosine-rectangular voltage, weak spots in the cable can be safely brought to a break-down. The benefits of the VLF method with 0.1 Hz cosine-rectangular voltage have been confirmed by multiple studies and practical field tests. The proven voltage is recommended by the Cenelec HD 620/621, IEC 60502-2, and IEEE 400.2 standard.
■The VLF CR-60-HP test system can be used both as a stand alone system (permanently installed in a transportation container for operations such as cable testing on offshore wind-farms) or integrated into a test van system. The integrated safety system and breakdown recognition software maximise safety.
■Furthermore, the leakage current measurement enables a qualitative assessment of the cable, and the protocol function allows test data to be printed and stored for further reporting purposes.
