Fisher TW-82P Digital Line Tracer

With Passive Power Detection

The TW-82P Digital Line Tracer components include a transmitter, receiver and ground-rod assembly.

The TW-82P is an active single-frequency and passive power current line tracer that is used to locate and trace buried utilities using any of the following four tracing methods:

Conductive Method

With this method, the Transmitter energizes the buried utility by making a direct electrical connection to it with Conductive Tracing Cables. In most cases, this method generates the strongest magnetic field for the Receiver to detect above ground.

Inductive Method

When a direct physical connection to the utility is unavailable, the utility may be energized indirectly by magnetically coupling an energizing current from the Transmitter. Some prior knowledge of the utility’s location is required so that the Transmitter can be placed and oriented, on the ground, near the utility in the most effective manner.

Coupling

In some cases a utility may be exposed, but does not provide a direct connection for the conductive tracing cables. The optional accessory coupling clamp can be clamped around the exposed utility to magnetically couple an energizing current from the Transmitter into the utility.

Passive Power

50Hz and 60Hz electric current flows on underground power lines and also on underground utilities that are not power lines. In Passive Power Mode, the TW-82P can detect this electric current using the Receiver as a stand-alone instrument without need for a transmitter.
