Product Overview
Key Features
Sandi VLF testing is used for any application requiring AC testing of high capacitance loads. The major application is for testing solid dielectric cable, followed by testing large rotating machinery, and occasionally for testing large insulators, arrestors, and the like.
Even if a utility doesna t adopt Sandi VLF for widespread cable testing, one of the best reasons to use VLF is to check installation quality and accessories, like splices. Many failures are due to damage during installation, improper workmanship, and/or insulation damage caused by excessive voltage fault locating - thumping. At the very least, every newly installed or repaired cable should be Sandi VLF tested before re-energizing.
