S-44 VLF (230 V) High Voltage Insulation Tester Ultrasonic Detector small and practical housing allowsDescription Test the condition of the cables with VLF or DC slow voltage The S 44 VLF high voltage insulation tester is a compact, robust and portable kit for testing medium voltage cables according to IEEE400, IEC 60502 2, CENELEC HD 620 and 621 and DIN VDE 0276 620 and 621. The test is carried out using the low electrical stress method, with a VLF (Very Low Frequency) voltage of 0. 1 Hz. The VLF test is the fastest way to detect insulation damage.
