VLF CR40 kV - "Very Low Frequency" 0.1 Hz Test

SebaKMT´s portable VLF 60 is designed for HV-tests on cables with a rated voltage of 35 kV or the VLF 40 for cables up to 22kV.

Using the patented SebaKMT Cosine-Square Wave shaped voltage form, with energy regeneration, weak spots in PE/XLPE and paper insulated lead cables can be brought to a breakdown quickly, without unnecessary strain on the cable insulation.

High quality voltage sources and the use of a semi-conductor switch, free of wear for the generation of a regular polarity reversal, guarantee a long life-span. A polarity transition corresponding to the 50 Hz mains voltage is a salient feature.

The optional leakage current measurement permits a direct quality assessment during the test procedure.

Technical Features:

• Powerful, portable and universal cable test system.
• Modular design (power module and control module) with an individual weight of approx. 50 kg
• Optional module "leakage current measurement" and "output doubling" to individually suit the system to specific test requirements.
• Optional Module "data recording" for comfortable und easy on the spot recording of the test results, the central administration of the test parameters and for reproducible test procedures.
• Automatic breakdown recognition
• Fast, on the spot installation without complicated setup, with shockproof sockets and integrated discharge devices to comply with the highest safety standards.
• With the patented technique of energy storage during the polarity reversal of the VLF voltage, it is possible to achieve a very low power consumption while simultaneously achieving a high testing capacitance.
• VLF 0.1 Hz testing is recommended, allowing high cable capacitance, and is the most effective method for testing PE and XLPE cables.
