VLF Sine Wave 45 kV

The VLF Sine Wave 45 kV is a compact VLF sine wave test system with optional integrated tan delta. It is a useful instrument for the commissioning, testing, and condition analysis of medium voltage cables. This unit performs very low frequency (VLF), DC, and sheath integrity testing as well as sheath fault pinpointing when combined with the optional ESG NT step voltage probe. Ideal for both routine testing and complicated diagnostics, the VLF Sine Wave 45 kV has a multi-purpose design with a continuous duty cycle.

For 0.1 Hz sine wave, rectangular, or DC voltage tests, the VLF Sine Wave 45 kV provides enhanced voltage quality and stability. In the event of excessive charge, its current integrated breakdown detection shuts down the test, ensuring limited damage to the cable. Up to 1000 measurements can be stored in the internal memory and results can be viewed on the unit or downloaded via the USB drive to the included Easyprot software for reporting.

An optional internal tan delta test is available that automatically evaluates results for PE, XLPE, and PILC type cables based on insulation and selected compliance standard.
