Short answer: BAUR protrac Pin-Pointing System should be selected by matching the complete test workflow to the application, not by comparing one headline specification. Confirm the test object, measurement range, accessories, environment, reporting needs, and local support before committing to a configuration.
Start with the measurement objective and the decision the result must support.
Evaluate the instrument, connections, accessories, software, and reporting as one system.
RCC Electronics can help Canadian teams confirm configuration, availability, service, and brief rental needs.
Interest in BAUR protrac Pin-Pointing System normally comes from a specific measurement problem: a test takes too long, a result is difficult to repeat, an operator needs safer access, or an existing setup no longer provides enough confidence. The model name alone does not answer whether the complete system will work in the intended environment.
This article combines the existing product overview with a structured evaluation method. It covers application fit, accessories, workflow, result review, Canadian support, and questions to ask before purchasing. Confirm the exact configuration and current specifications with the manufacturer documentation and RCC Electronics before relying on any individual capability.
Is this instrument a practical fit?
A useful evaluation begins with five questions. Write the answers before requesting a quotation or demonstration. This prevents an attractive specification from masking a mismatch in connections, operating conditions, test time, or documentation.

Technical overview and application context
Maintaining a reliable power supply is and will remain extremely important. To ensure a reliable power supply, a high-performance power grid and short downtime are crucial.
Often, faults on underground cables result in partial or total failure of the power supply and can lead to high repair and restoration costs. It is only through fast and precise cable fault location that repairs can be made quickly, to keep costs as low as possible and minimise downtime.
protrac Pin-Pointing System
An animation explaining how protrac combines acoustic-magnetic fault pin-pointing, step-voltage sheath fault location, and audio-frequency route tracing in one field system.
Acoustic-Magnetic Pin-Pointing
A surge generator triggers breakdown at the fault. The AGP receives the electromagnetic impulse and the delayed acoustic signal, then the CU guides the operator toward the strongest and most consistent point.
EM reference pulse
Acoustic arrival
Principle
The fault flashover creates an electromagnetic reference pulse and an acoustic pressure wave. The time difference and signal strength guide the operator to the fault.
Best used for
Precise ground confirmation after pre-location, especially when the cable route is not straight or the excavation point must be reduced.
BAUR protrac elements
CU control unit, AGP acoustic ground probe, wireless audio output, and a surge voltage generator.
Signal qualityUse peak acoustic response together with timing; do not rely on loudness alone.
Noise controlAdaptive noise suppression helps separate fault sound from traffic and site noise.
Field correctionCompare the mark with route data, depth, ducts, joints, and surface conditions.
Step Voltage Sheath Fault Location
For sheath and earth faults, voltage is applied to the faulty sheath. Current spreads through the soil and creates a surface voltage gradient that the SVP probes can follow.
Principle
The operator walks across the voltage gradient. At the fault point the measured polarity reverses, confirming the physical location.
Best used for
Cable sheath faults and earth faults where the fault current leaves the sheath and enters the surrounding soil.
BAUR protrac elements
CU control unit and SVP step voltage probes. BAUR lists a step-voltage measurement range of 1 microvolt to 220 volts for the step voltage set.
Engineering Parameters
Voltage gradientSearch for increasing step voltage as the probes approach the sheath fault.
Polarity reversalThe direction change at the fault point is the final confirmation cue.
Measurement rangeBAUR states 1 microvolt to 220 volts for the protrac step voltage set.
Probe spacingUse wider spacing for rough search and shorter spacing for precise confirmation.
Audio Frequency Cable Tracing
The audio-frequency signal is coupled into the cable. The AFP probe follows the electromagnetic field to map the route, direction, and depth above ground.
Principle
The probe evaluates the field around the conductor. Route history and depth readings help align the physical path with the pre-located fault distance.
CU control unit, AFP audio frequency probe, and audio frequency generator. BAUR highlights direct and 45-degree depth measurements and 3D space-coil evaluation.
Engineering Parameters
Frequency selectionChoose the tracing frequency to fit distance, coupling, interference, and site conditions.
Depth readingsUse direct and 45-degree depth measurements as guidance before excavation.
3D coil dataSpace-coil evaluation helps reduce manual alignment errors while following the route.
Interference checksConfirm against nearby utilities, bonded screens, fences, and parallel cables.
protrac Set Architecture
protrac sets can be configured for multifunctional pin-pointing, tracing, acoustic work, or step-voltage work, using shared field components around the CU control unit.

Recommended Field Workflow
1. Pre-locate firstUse TDR or surge-based pre-location to estimate the distance to the fault before final ground search.
2. Confirm the routeUse AFP tracing when the physical cable route may deviate from the straight electrical distance.
3. Pin-point the exact spotUse AGP acoustic-magnetic detection or SVP step voltage depending on the fault type.
4. Mark and documentRecord position, mode, signal behavior, operator notes, and site constraints before excavation.
How to evaluate BAUR protrac Pin-Pointing System for your workflow
Define the test object and normal operating condition first. Record the expected range, the smallest change that matters, the maximum condition the setup may encounter, and whether the result is for troubleshooting, acceptance, maintenance trending, production screening, or engineering analysis. These uses can require different accuracy, speed, isolation, memory, automation, and documentation.
Next, map the complete connection path. Include probes, clamps, sensors, fixtures, test leads, adapters, communication cables, power sources, and protective equipment. Check connector compatibility and physical access as carefully as the instrument specification. A technically capable main unit can still be the wrong choice if the required accessory is unsuitable for the conductor, terminal, frequency, voltage, temperature, or installation space.
Finally, test a representative workflow. Time the setup, confirm the operator can identify a poor connection, save the result, reproduce the measurement, and export the evidence in the format the team actually uses. A short application review or demonstration often reveals more than a long feature comparison.
Planning the measurement and reviewing results
Reliable results come from a controlled method. Document the test conditions, instrument configuration, accessory identifiers, connection points, stabilization time, environmental conditions, and any correction or compensation applied. Where safety procedures or isolation steps are required, include them in the job plan and follow the equipment manufacturer and site rules.
Before collecting production or field data, run a reference check on a known item or a repeatable baseline. Repeat the measurement after reconnecting when connection quality could influence the result. Review the raw value together with range status, warning indicators, time stamps, waveforms, trends, or phase information that the instrument provides. A single number without context can hide a setup problem.
For purchasing decisions, compare the evidence produced by each candidate under the same conditions. Separate mandatory requirements from useful conveniences, and include the cost of accessories, training, software, calibration, downtime, and future expansion. This produces a more defensible decision than comparing list price or one maximum specification.
