Megger VLF Sine Wave 34 kV

The VLF Sine Wave 34 kV is a compact, robust and portable VLF sine wave test system for medium voltage cables. The VLF Sinus test system enables testing of medium-voltage cables in accordance with the CENELEC Harmonization Documents HD 620 S1:1996 und HD 621 S1:1996 with a 0.1 Hz sine wave voltage of up to 24 kV RMS. With the aid of such cable testing, faults in the insulation - particularly water tree damage - will be reliably made to flash over in PE/XLPE cables but also in paper insulated cables. The test procedure does not damage fault-free insulation. The design, optimised for rapid transportation and quick setup, and the continuous duty cycle are two attributes that qualify the system as an ideal tool for routine cable testing. For both 0.1 Hz sine wave voltage tests and rectangular or DC voltage tests, the VLF sine wave 34 kV fills the highest demands on the test voltage quality and stability. Moreover, the integrated “breakdown detection“ shuts down the test voltage in the event of an excessive charge current and guarantees limited damage to the cable. Consistent single-button operation combined with a sophisticated operating concept allows a fast and targeted use of the system. FEATURES Testing without operational interruptions. AC testing in compliance with DIN VDE, EN, IEEE. Compact, rugged, lightweight and IP 54 for transportation. Sheath testing and sheath fault pin-pointing acc. to IEC 60229. Maximum user safety through automatic discharge of the test object and earth loop ground monitoring. Breakdown detection and load recognition (R, C). Quick & easy logging, and updates via USB port.
