information
In combination with Surge Voltage Generators (SSG / STG) or Audio Frequency Generators
(TG20/50 and TG600) and accessories like BM 30, earth sticks, the Universallocator UL 30
is used for:
-
pin-pointing of cable faults
-
route tracing of buried cables or metallic pipes
-
propagation
time
measurement
-
Cable sheath fault location
-
Combined tracing and pin pointing
With the help of an audio frequency transmitter (TG20/50 or TG600) an electromagnetic field
in the cable is generated.
Depending on selected tracing and measuring methods, the detection is done by an
electromagnetic sensor
The received electromagnetic and acoustic signals are amplified and indicated by the Audio
Frequency Receiver UL 30:
-
acoustically via the integrated loudspeaker or a headphone (to be connected)
-
optically on the integrated LCD display.
In connection with a Surge Voltage Generator SSG the surge voltage impulse (magnetic
field) is indicated on the pointer UL 30 when performing a coincidence measurement. The
impact noise is heard via headphone of the loudspeaker.
With the propagation time measurement the time difference between magnetic and acoustic
impulse is evaluated. The minimum of the time difference indicates the cable fault position.
Special advantages:
-
at cable faults which acoustically are very difficult to locate, the coincidence
measuring method gives additional help to verify the faulty point.
-
with cables in pipes the fault position can be located accurately above the cable
route.
