3.0 OPERATING PROCEDURES
The TRF-100 should always be grounded with the provided ground cable before connecting H
and X cables. The transformer bushings should also be grounded before connecting test leads
to the transformer. This will prevent inducing any voltages into the TRF-100. All transformer bus
connections must be removed, and the transformer must be isolated before performing any
tests. Typical transformer connection diagrams are illustrated in the sections below.
