3.0 OPERATING PROCEDURES
The ATRT-03 S2 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 ATRT-03 S2. 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.
