Sulz (Austria), August 2022 – Where's the cable? Where exactly is the fault? Measurement engineers now get a much faster and satisfactory answer to both of these questions as BAUR has now added the AFP audio frequency probe to the protrac® system to provide valuable functions for cable fault pin-pointing and tracing with audio frequency. The AFP audio frequency probe has a 3D Space coil, which simplifies handling and delivers more accurate results. This in turn speeds up both the cable tracing and the pinpointing short-circuits between phases. In fact, the audio frequency probe has four coils – the fourth coil is used for the depth measurement, which can be done as a direct measurement or by the 45° angle method. Using these two measurement methods, it is possible to reliably determine the laying depth, even in difficult conditions. This reduces the risk of imprecise, lengthy excavations and potential cable damage.
The AFP is easy to operate: there is no need to manually align coils or the receiver, and all important information can be captured and verified in a single sequence. Operators are able to use the minimum, maximum, C-Max or twist and minimum distortion methods process to carry out their task. Assistance is provided during tracing by the Tracing Compass function and the Deviation Alert, which indicates interference (e.g. by overhead lines), avoiding leaving the correct route. The BAUR 3D History Track is another innovative and helpful display function. It presents the data of the 3 coils over the lapsed time period, simplifying the twist and minimum measurement and thus the determination of lay length, joint or fault positions.
The all-in-one system
The new BAUR AFP audio frequency probe completes the available range of tracing and cable fault pin-pointing solutions. With the CU control unit, the AGP acoustic ground probe, the new AFP audio frequency probe, the SVP step voltage probe and optional Bluetooth® headphones, the protrac® system now offers everything the operator needs, as the clearly uncluttered set supports:
* Acoustic/magnetic pin-pointing with surge voltage generator
* Twist method for locating short-circuits in 3-phase cables
* Minimum distortion method for locating short-circuit faults in coaxial cables.
* Tracing with all known methods (minimum, maximum, C-Max)
* Measuring probe for locating sheath and earth faults
