92510 - Oil Circuit Breaker form
Basic Form Information
The PF Oil Circuit Breaker form is used for power factor testing medium and
high voltage bulk oil circuit breakers. These are typically found in transmission
and distribution substations.
Oil circuit breakers usually utilize condenser bushings with test taps which
should be routinely tested whenever the overall insulation of the breaker is
tested.
Test modes are mentioned in the description of tests below. However, the test
form is pre-programmed with the appropriate test modes to automatically be
performed.
