VLF CR 40 kV

VLF CR 40 kV

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 reproduceable 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.

	Basic instrument
	HV-connection cable 5 m
	Connection cable
	Accessory bag
