Baur ATG 2 BAUR burn down transformer

Converting Faults for Easier Location

In the complex and critical world of electrical power networks, cable faults represent a major challenge. These faults can be highly resistive, difficult to pinpoint, or even intermittent, making them frustratingly hard to locate and repair. Traditional fault location methods often struggle with these types of issues, leading to prolonged network downtime and significant economic losses. The solution lies in a specialized piece of equipment known as a burn down transformer. This device is designed not to repair the fault directly, but to transform its nature, converting a high-resistive, hard-to-find fault into a low-resistive one that can be easily located using standard fault location techniques like Time Domain Reflectometry.

Introducing the ATG 2 Burn Down Transformer

The ATG 2 burn down transformer is a highly effective tool used for the impedance reduction of cable faults in low and medium-voltage networks. It is a powerful and sophisticated device, yet it remains simple and safe to operate. The ATG 2 is specifically engineered to handle the most challenging faults, taking an intermittent or high-resistive fault and “burning” it down to a stable, low-resistive state. This crucial conversion allows maintenance professionals to use conventional and more accurate methods to pinpoint the exact location of the fault, drastically reducing the time and effort required for repairs.

Technical Excellence in a Compact Design

At the heart of the ATG 2 is a short-circuit proof 2300 VA stray field transformer, a testament to its robust and reliable construction. This transformer delivers a maximum DC voltage of up to 10 kV. It is housed in a fully enclosed 19-inch casing, ensuring it is both durable and safe to use in various environments. A key feature is the ability to adjust the output voltage across six distinct levels, a function that can be performed even under load. This allows technicians to perfectly match the voltage to the specific characteristics of the cable fault, optimizing the burning process for maximum efficiency and speed.

Controlling Voltage and Current Precisely

Precision control is a hallmark of the ATG 2. Beyond the six voltage levels, the instrument provides an additional layer of control with independent potentiometers for both current and voltage. This allows the operator to limit the current and voltage on each level, ensuring a controlled and safe burning process. This level of fine-tuning is essential for preventing further damage to the cable while effectively reducing the fault impedance. This combination of coarse voltage levels and fine-tuned potentiometers gives the technician unparalleled control over the fault conversion process.

Essential Safety and Monitoring Features

Safety is paramount when working with high voltage, and the ATG 2 is built with numerous features to ensure the protection of both the operator and the equipment. It includes an automatic switch-off function in case of a temperature rise, which is also accompanied by an acoustic alarm to alert the user. The device also has an automatic discharge unit, a critical safety feature that ensures all residual high voltage is safely discharged after the operation is complete. Furthermore, a switch-on interlock prevents high-voltage activation without proper preparation, and the safety control unit is designed according to DIN EN 50191 standards. These features make the ATG 2 one of the safest burn down transformers on the market.

Versatile Applications for Cable Networks

The ATG 2 burn down transformer has a wide range of specific applications that make it an invaluable tool for cable network maintenance. It is primarily used for low and medium-voltage networks. A special AC voltage level is included for low-voltage applications, providing additional versatility. Technicians can use it to treat high-resistive faults caused by insulation breakdown, converting them to a low-resistive state. It is also highly effective in handling intermittent faults, which can be particularly challenging because they come and go, making them difficult to locate with a standard Time Domain Reflectometer (TDR). By using the ATG 2, these faults are made permanent and stable, allowing for a precise and efficient location and repair. The optional connection for an external ohmmeter allows for on-site determination of fault resistance, enabling the technician to evaluate if additional burning is required.

Seamless Integration into Your Workflow

The ATG 2 is designed for flexibility and ease of integration. It can be used as a stand-alone version for independent operations, or it can be seamlessly built-in as a module within BAUR cable fault location systems. This modularity makes it a perfect addition to an existing fleet of diagnostic tools, allowing companies to enhance their fault location capabilities without a complete overhaul of their equipment. An external emergency stop unit with signal lamps can also be connected, adding another layer of safety and control, making the ATG 2 a versatile and reliable component of any cable maintenance toolkit.
