Megger VLF Sine Wave 45 kV Cable Tester

Overview

The Megger VLF Sine Wave 45 kV is a portable cable test system that applies a true sine-wave very-low-frequency (VLF) test voltage for commissioning, maintenance and condition assessment of medium-voltage cables. Sine-wave VLF testing stresses cable insulation in a controlled, standardised way while keeping the equipment compact and transportable, and this 45 kV model adds automatic frequency control and a modern touchscreen interface for fast, efficient field testing of longer cable runs.

It delivers up to 45 kVpeak (32 kVrms) as a true 0.1 Hz sine wave, and can also perform DC and VLF rectangular tests, handling loads up to 10 µF. Automatic frequency control from 0.01 to 0.1 Hz adapts to the cable’s capacitance so even long cables are tested efficiently. Safety features include breakdown detection, earth-loop monitoring and automatic discharge. Results (over 1000 records) are stored internally and exported by USB or through MeggerBook software, and the system supports optional tan-delta diagnostics with IEEE 400.2 evaluation, sheath testing to IEC 60229 and PD measurement via the PDS 62-SIN attachment.
