Identification Of Routed Power Cables; 11�15 Finding Interruption In Grid Lines - VOLTCRAFT LSG-10 Operating Instructions Manual

11.14 Identification of routed power cables

Switch off the fuses and power down the electrical cir-
cuits�
The different wires in the cable must be twisted on one
side so that they are electrically conductive� Connect the
transmitter with two poles to the cable to be tested at the
open cable side�
Where several transmitters are used, the work effort for
moving the transmitter elsewhere� When several trans-
mitters are used, every transmitter needs a separate
signal code�
Move the receiver along the cables' twisted side� The
respective signal code is indicated on the display The
cables can be identified.
11.15 Finding interruption in grid lines
This test does not require a transmitter�
The mains cable must be under mains voltage�
Put the transmitter into the contact-free voltage test mode "NCV"� Move the
receiver along the mains cable starting at the outlet� When the mains volt-
age is recognised, a signal sounds and the bar display is activated�
When the break is reached, the sound goes out and the bar display disap-
pears�
Note:
– The tone height and deflection of the bar display depends on the
distance and voltage height of the mains cable�
– Repeat the test with the mains plug turned by 180°� This prevents
overlooking an interruption of the neutral conductor�
A higher tone is no secure sign for the voltage height, though� Reliable voltage measurement is only pos-
sible with a suitable measuring device with a value display�
