With the cable manufacturer production scale, power cable production type, sales volume increased year by year. For the actual production process requires cable fault resolution and customer site cable fault location, many cable manufacturers have to buy a cable fault detector configured to solve cable customers to use the actual production process and the scene of various types of cable failure. Since the crossover ethernet cable into a high impedance fault type, low resistance, break and complex fault, therefore, the current market of cable fault detector are generally high and low voltage configuration, including components and accessories more, a set of equipment Components ranging from 5-6 pieces, as many pieces as much as 10-11. As cable manufacturers, both on the factory production process in the various cable fault locating timely treatment, crossover ethernet cable to ensure timely product delivery; while also taking into account the customer's site to complete the laying of the cable or cables running conflict Fat locate the fault. Therefore, as the cable manufacturer, to purchase the cable fault detector are high and low voltage buy configuration, device components are 6-10 pieces, in the face of buried cable fault locating the customer's site appears, the entire device handling and transport must have a special cable fault detection car shipped, otherwise the quality of transport equipment not guaranteed.
Currently on the market selling cable fault detector is divided into two types, one is designed in accordance with the principle of echo method cable fault detector: The main components include intelligent waveform detection analyzer, path analyzer, DC high voltage generator (including operating Taiwan and AC and DC high voltage test transformer), capacitors, ball gap, fixed instrument, such as; there is a method in accordance with the principles of bridge design and manufacture of cable fault detector, the main components of the package Fault Locator Bridge (high and low voltage bridge) , pointing device, path analyzer, wave reflection method fault locator and so on. Both cable fault detector includes a cable fault coarse side positioning portion and pinpoint parts.
Cable fault detector at the production site and customer service on-site use, often moving or long-distance transport, in order to ensure the integrity of the cable fault detector transport and use, the cable fault detector for routine maintenance and management is particularly necessary. Now there are a lot of buying power supply bureau with cable fault detector, and with the use of specialized testing personnel, and the actual use of the frequency cable fault detector is not too high, so the use of the device itself due to transportation cause failure probability is not too high. But for cable manufacturers, by its cable product type, actual production, sales restrictions, instrument failure in the factory and on site usage to some of the more high-powered Bureau. Sometimes in the cable plant, probably more than one workshop in conjunction with a cable fault detection equipment, resulting in cable fault detector will often be moved around, some small component parts, such as headphones, signal lines and sometimes moving back and forth in the workshop , there will be loss and damage phenomena. As for cable fault detector by long-distance transport (air cargo passenger) to the customer site for cable fault location services have become even more complicated
