A sheath testing function and pulsed-output-voltage for sheath fault pinpointing complete the module’s testing options.ĭata can be saved to a memory stick with the optional logging function. Megger solved this problem by developing EasyTest 20 kV with an output voltage of 20 kV and 0.1 Hz AC at 0.5 μF (and up to 2.5 μF at 0.02 Hz), the EasyTest 20 kV provides sufficient power to test 20 kV cables that are up to 2 km in length at 0.1 Hz with a test voltage of 1.7 Uo.Ī DC voltage module with leakage current measurement is available for testing with both PVC and PILC. Way, which leads to breakdowns during operation following the test. Hidden problems cannot be detected in this This current practice, it is clear that DC voltage tests can only reveal

Moreover if the cables are old, the polarisation effects ofĭC voltage testing can cause additional ageing or damage. Well-known fact that DC voltage testing is useless, particularly for Either simple DC testers or insulation testersĪre used however, with maximum voltages of 10 kV, they seldom come Typically, a test is performed in accordance with company specifications after repairs, or after a new cable has been installed.Ī typical method of testing is a five- or ten-minute DC test in the The EasyTest 20 kV is a simplified version of the standard cosine rectangular VLF test. Risk and is in accordance with most standards and internal regulations Reconnecting the voltage without testing is a The Megger EasyTest 20 kV is a very small, lightweight testing device which offers the advantage of alternating voltage.Īnd reliable testing after installing or repairing cable systems has an Megger Seba EasyTest 20 kV - The Quick VLF Cable Tester
