2.2. Tracing the electromagnetic field of lines
a) Energized lines, the transmitter in LOAD mode
Hints:
When the transmitter is connected to energized lines the loop is determined with the
mains transformer.
Tracing this way will give the best results and selectivity because of high values of the
injected current.
The tracing principle allows accurate tracing even on longer distances.

Notes
Pair of
conductors
Up to 40 cm - one wall socket connection
Wide
conductor loop
Up to 2 m
- connection between L in one wall socket and N in
the other with separated conduits
Note: proper connection is indicated with LED LOAD
on transmitter (LED lights when voltage is present)
Hints, continued:
The position of the Receiver must be considered (see the figures below)! Also wire
direction can be defined this way.
