The primary application of the Intercom SA 32 is as „aid“ for pre-
locating of cable faults. It allows locating of high-resistance faults
utilizing the secondary impulse method (SIM).
This allows for transformation of high-resistance faults into low-
resistance faults. The surge voltage impulse of the SSG is
consequently led to the test object via the high-performance
resistors. The subsequently optained extension of the surge voltage
impulse allows triggering the echometer, which sends the
„secondary impulse“ via capacitive coupling, for pre-locating of the,
at this moment, low-resistance cable fault.
Additionally, the SA 32 features a mA-meter with a decade
measuring range switching. The high-performance resistor and the
mA-meter can be shorted via the pull switch. In the SA 32 the
discharge unit of the surge voltage generator is enhanced by a
built-in earthing unit which is tripped with a time delay.
The SA 32 is supplied by the SSG and is included in the safety
system.
The folding tripod can be supplied as an additional special
accessory. It allows for convenient working conditions in case a
working table is not available. The working height is approx. 90cm.
The EMERGENCY OFF unit serves as part of the safety
precautions around the danger area. Signal lamps and
EMERGENCY OFF pushbutton switch are mounted on a cable
drum. The EMERGENCY OFF unit is available with a 25 m or
50 m connecting lead.
