Cable Fault Location System is a comprehensive cable fault detection instrument, which can test high-resistance flashover faults, high and low resistance grounding, short circuits, cable breaks, poor contact and other faults. The cable fault locator is equipped with an acoustic pinpointing device, which can be used to accurately determine the exact location of the fault point. It is particularly suitable for testing various types of power cables and communication cables with different voltage levels.
Detection Methods
The cable fault locator adopts multiple detection methods and applies the most advanced electronic technology achievements. It uses computer technology and microelectronics technology, featuring high intelligence, complete functions, wide application range, accurate testing, and convenient use.
Locator Design
Detecting aircraft cable faults is very important in civil aviation maintenance; based on the characteristics of aircraft cables, a method for effective testing and diagnosis is proposed - the low-voltage pulse method, and using microcontroller and CPLD technology, an aircraft cable defect detection and location device is designed; the locator mainly consists of three parts: signal acquisition circuit, system control circuit, and human-computer interaction circuit; at the same time, two sets of crystal oscillators are used to ensure high-speed signal acquisition and meet the low-speed processing of the system, with characteristics of low cost, light and flexible, and accurate testing; in addition, besides being applied to aircraft cable maintenance, it can also be further applied to short-distance cable testing and defect detection in telecommunications, electric power and other departments.
Related Applications
In the power industry and some industries that use cables, especially in some complex power systems, it is very difficult to find faults in underground cable lines. However, in this regard, equipment with multiple functions and easy operation continues to emerge, which can not only reduce the high cost of fault detection, but also reduce the inevitable long-term power outages during the arduous search for cable faults, bringing a lot of convenience to troubleshooting.
Direct Buried Cables
Detecting faults in underground direct buried cables and underground residential distribution (URD) systems is a very time-consuming task and can cause very inconvenient power outages to users, and some techniques may damage the cables. For some equipment with high technical requirements, the operation is relatively complex, and only strictly trained operators can use it, which brings many inconveniences to the promotion and application of such technical equipment. Therefore, choosing the appropriate technology depends partly on the knowledge of cable system design that the fault detector designers understand, and partly on the professional technical knowledge of the equipment and operators in this field. Having the right equipment and professional technology on site is the first step to quickly and effectively detect faults.
