About this document
VLF Testing for Shielded Power Cables by Daniel Díaz is a document available to read on EtoBox.
VLF testing of shielded power cables is recommended over DC hipot testing to detect defects in solid dielectric cables that would lead to failure. VLF testing uses very low frequency AC voltages that can initiate partial discharges in defects without building up space charges that can damage the cable insulation. The IEEE has established guidelines for VLF cable testing including recommended test voltages and durations. VLF testing is shown to reduce cable failure rates and allow repairs to be performed pro
