0 – 60 kVAC, load rated to 5.5 uF
VLF testing is used for any application requiring AC
testing of high capacitance loads. The major application is for
testing solid dielectric cable (per IEEE400.2), followed by testing
large rotating machinery (per IEEE 433- 1974), and occasionally for
testing large insulators, arrestors, and the like.
Even if a
utility doesn’t adopt 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 VLF tested before
re-energizing.
