VLF SIN 45
Compact VLF sine wave test system
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.
The VLF Sine Wave 45 kV is a compact VLF sine wave test system
