5.4 Identifying grid voltage and searching for breaks in circuits
Requirements:
The circuit must have AC voltage.
Measurement must be performed as shown in Fig. 3-4.
Set the transmitter to “grid identification” (UAC) mode.
1. The AC signals found by the transmitter in UAC mode only show whether the circuit has current;
determination of the exact voltage is done with the voltage measurement function of the transmitter.
2. When searching for the ends of compound cables, each wire must be separately connected to the
phase conductor.
1. A transmitter is not necessary for this application (unless you want to use the measurement function
of the transmitter to determine the voltage in the circuit).
2. The columns shown on the transmitter for signal strength and signal tone frequency are associated
with the voltage in the circuit under search and the distance from it. The higher the voltage and the
less the distance to the circuit, the more columns are shown and the higher the signal tone frequency.
