Signal Current Measurement can also help
to identify the layout of pipe and cable networks
as the main line after a ‘T’ will have most
of the Signal Current remaining on it
whereas the shorter connection
will have correspondingly less.
The Signal Current reading should also reduce
at a uniform rate as the distance from
the Transmitter increases. A sudden drop
in Signal Current, in a short distance,
indicates a change to that service such
as an unknown connection, an insulated
joint or a break in the pipe or cable.
