13.1 About acoustic pin-pointing
Acoustic pin-pointing is suitable for pin-pointing high-resistive cable faults and cable and
phase breaks in buried cables and cable systems. The prerequisite for applying this method is
that a breakdown must take place at the fault.
Surge voltage pulses are fed into the faulty phases of the cable, which lead to breakdowns at
the fault. The breakdowns result in an acoustic and magnetic signal. During acoustic
pin-pointing, a ground microphone is used to look for the location where the breakdown noise
is loudest. The breakdown noise can be best heard directly over the fault.
13.2 Setting parameters for the acoustic pin-pointing
On the system control panel
1. Press the MENU key on the display.
2. Select the SURGE MODE menu item and press the DEF. key.
The MAX.OUTPUT VOLTAGE view is displayed.
3. Use the arrow keys to set the maximum permissible output voltage and press the ENTER
key.
The DEF. PULSE view is displayed.
4. Use the arrow keys to set the desired surge sequence (1 – 20 pulses/min) and press the
ENTER key.
The OUTPUT POWER view is displayed.
5. Depending on the intended output voltage, select a voltage range:
 Voltage range 0 – 8 kV: Select the symbol (parallel connection).
With parallel connection, at 8 kV you receive the max. surge energy of 1024 J in the
surge voltage range.
 Voltage range 0 – 16 kV: Select the symbol (series connection).
With series connection, at 16 kV you receive the max. surge energy of 1024 J in the
surge voltage range.
6. Press the ENTER key.
The parameters are saved.
