Megger 656601 Energized Cable Route Tracer
Megger 656601 Energized Cable Route Tracer Identifies Underground Power Cables
The MEGGER 656902 Energized Cable Route Tracer is an electronic instrument designed for locating tracing, and measuring the depth to ac energized underground power cables and pipes from the surface. T he instrument can also be used to locate underground transformers, T-splices, Y – splices, and ground faults on unshielded cable. It is identified as as Catalog No. 656601 Energized Cable Route Tracer and supplied with a switchable 60 Hz filter. The unit senses the magnitude and direction of the effective electromagnetic field generated by conductors carrying dc impulses or ac loads up to 1000 Hz. MEGGER 656902 Cable Route Tracers operate on loaded 50 Hz and 60 Hz single-phase power cables. Three-phase ac power cables, dc power cables, cables surrounded by other 50 Hz or 60 Hz energized cables, and faulted cables can be traced by applying a distinctive audio frequency tone of 1000 Hz or less from a tone generator.
MEGGER 656601 Energized Cable Route Tracer Uses Radio Frequency Technology to Determine Cable Depths
Megger 656601 Energized Cable Route Tracer’s transmitter energizes the underground metallic line with a radio-frequency signal that is then detected by the receiver. The metallic line can be energized either inductively (no direct connection required) or conductively (through direct connection to the line). The transmitted signal can be identified by either peak detection (maximum signal) or null detection (absence of signal). The sensitivity readily detects the presence of 1 ampere ac flowing at a depth of 6 feet under the surface in the absence of adjacent
metallic conductors. The Megger 656601 Energized Cable Route Tracer consists of a transmitter, which energizes the cable/pipe/line. Once the cable/pipe is coupled with the radiated signal, the cable behaves like a long large antenna. It re-transmits the signal through the ground and air in a pattern that corresponds to the cable’s path. The line carries the signal along its path for several hundred yards, depending on its depth, soil mineralization and ground conductivity. With a detectable traceable signal and the portable receiver, the transmitted signal radiated from the power cable or pipe is detected and the route is traceable. The transmitter can energize the line either by magnetic induction from a built-in antenna or by direct conductive connection which is superior to inductive coupling.

Energizing the line conductively provides increased tracing distance and minimizes signal coupling to other lines. The conductive mode of operation requires the line to be exposed so that a direct connection can be made. Conductive energizing is preferred over inductive energizing because it results in more highly defined signal coupling. The signal generated does not spread to other conductive lines in the vicinity of the
traced line. Using a ground rod with the direct connection increases the energizing efficiency and, therefore, the length of line that can be traced. Inductive coupling, which does not require a mechanical connection to the line, permits a buried line to be traced without uncovering or de-energizing or powering the line down. The receiver can be used to trace lines using either peaks (detection of the maximum signal) or nulls (detection of the minimum, or zero, signal).
