VLF Testing

VLF or Very Low Frequency (VLF) 0.1 Hz testing is used on cables as an alternative to DC testing.

Very Low Frequency test sets are used to verify the dielectric integrity of the cable under test, be it for commissioning/ acceptance testing or for maintenance testing. VLF sinusoidal and VLF Cosine Rectangular (CR) are the two most common and standardized wave shapes used for VLF testing
