Baur shirla Cable sheath testing and fault location device

An All-in-One Cable Fault Solution

In the intricate landscape of electrical infrastructure, a cable fault can trigger a cascade of problems, leading to power outages, operational downtime, and significant financial losses. Identifying and repairing these faults quickly and accurately is a paramount concern for utilities and maintenance professionals. The BAUR shirla is a groundbreaking solution that addresses this challenge head-on. As a comprehensive sheath test and fault location device, it is engineered to handle multiple critical tasks in one compact unit. It not only performs essential cable and cable sheath testing but also provides a dual-stage fault location process, combining highly accurate pre-location with precise pinpointing. This integrated approach ensures that technicians can transition from a broad diagnostic sweep to a targeted, pinpointed repair with a single device. The shirla‘s mobile design and robust construction make it the ideal companion for on-site use, empowering professionals to tackle complex faults with confidence and efficiency, ultimately restoring service faster and minimizing the impact of a fault.

Precise Pre-Location with Measuring Bridge

Before a fault can be pinpointed, its approximate location must be determined. The shirla excels at this initial step through its sophisticated pre-location functionality, which is based on the proven Murray and Glaser measuring bridge principle. This method is a cornerstone of resistance-based fault location, and the shirla‘s implementation is specially dimensioned for power cables, ensuring high accuracy and reliability. What makes this feature particularly powerful is its automation. The measuring bridge performs automatic zero balance and evaluation, eliminating the need for complex manual calculations and reducing the potential for human error. Once the test is complete, the fault distance is shown directly in meters on the screen. To further enhance accuracy, the system allows for the entry of up to 50 different cable sections, factoring in variations in length, conductor cross-section, and material. This advanced capability allows for precise measurements on complex, multi-section cable routes, providing a highly reliable starting point for the subsequent pinpointing process.

Pinpointing Faults with Step Voltage Method

After the pre-location has narrowed down the fault to a specific area, the real work of pinpointing begins. The shirla transitions seamlessly into this phase by generating a pulsed voltage up to 10 kV. This pulsed signal is the key to the step voltage method, a highly effective technique for precisely locating cable sheath faults and other faults due to earth contact. The method works by applying the pulsed voltage across the fault and a distant earth point, creating a voltage gradient on the ground surface. A technician, using a specialized sensor from the protrac® pinpointing system, can then follow this voltage gradient to the exact point of the fault, where the voltage polarity reverses. The shirla provides exceptional control over this process with four selectable pulse patterns and adjustable switch-on delays and operating times, allowing technicians to optimize the signal for different soil conditions and fault types. This combination of a powerful, pulsed voltage source and the intuitive step voltage method makes the shirla an unmatched tool for quickly and accurately finding the precise location of a fault, saving valuable time and effort in the repair phase.

Specialized Testing and Pinpointing Applications

The shirla is a true multi-functional device, with its applications extending across a range of critical electrical maintenance tasks. One of its primary uses is cable and cable sheath testing with DC voltage up to 10 kV. This fundamental test is crucial for assessing the integrity of the insulation and the outer protective sheath of the cable, helping to identify potential weaknesses before they lead to a full-blown failure. Beyond basic testing, the device’s main application is the pre-location and pinpointing of cable sheath faults and faults due to earth contact. Sheath faults, in particular, are a common problem that can allow moisture to ingress and cause long-term damage to the cable’s core insulation. The shirla‘s ability to precisely locate these faults enables preventative repairs, extending the operational life of the cable and preventing more costly and dangerous failures. Its versatility in handling different fault types, from those in standard power cables to those in lighting and control cables, makes it an indispensable tool for a wide range of professionals, from utility workers to industrial maintenance teams, all focused on ensuring the reliability and safety of their electrical network.

Flexible Power for Unrestricted On-Site Use

In the field, flexibility and reliability are non-negotiable. The shirla is designed to meet these demands with its adaptable power supply options. The device can be operated using a standard mains voltage supply (100–240 V AC), which is ideal for use in substations or other fixed locations. However, recognizing the reality of on-site work, the shirla is also equipped with an integrated rechargeable battery. This powerful DC 12 V, 3.4 Ah lead-acid battery provides approximately 45 minutes of operation in HV mode, offering ample time to perform testing and pre-location without a continuous power source. The battery can be fully charged in just four hours, ensuring the device is ready for the next job. This dual power capability, combined with a robust IP54 protection rating in its closed state, means the shirla can be used reliably in various weather conditions and environments. Its compact design and lightweight construction (approx. 17 kg) further enhance its mobility, with a separate transport case for accessories that keeps all necessary components organized and easy to carry.

Automation and Safety for Confident Operation

The shirla‘s advanced capabilities are matched by its intuitive and user-friendly design. The device features automatic measurement sequences and reporting, which simplifies the testing process and minimizes the need for manual intervention. The results are displayed on a backlit LCD screen with a clear resolution, and they can be automatically exported to a USB stick in a bilingual text format (English and German). This automated data management streamlines the workflow, eliminating the need for manual data entry and ensuring the accuracy and integrity of the test reports. In the realm of high-voltage testing, safety is paramount. The shirla is equipped with a comprehensive set of safety features to protect the operator. It includes an integrated discharge unit that safely dissipates stored energy after a test, and it has a dedicated connection for an external emergency off unit in accordance with EN 50191. These features provide a secure working environment, allowing professionals to operate with confidence.
