G) Locating Transformers, Splices, and Faults
1) Underground Transformers
To locate an underground transformer, the operator first
locates an energized cable connected to the trans-
former. He then traces the cable toward the trans-
former by the maximizing technique described previ-
ously. (Note -- the nulling technique cannot be used for
locating a transformer). Since the electromagnetic field
propagated from a transformer is many times greater
than that propagated from the cable, the signal
response will rise greatly as the operator walks into the
vicinity of the transformer and will continue to rise until
the detection rod is directly over the transformer. Each
time that the increased signal-response “pegs” the
