Cable Fault Tester How to Locate Cable Faults Cable Fault Tester Manufacturers Over the past two decades, the use of long high-voltage cables, many of which have been installed and buried underwater, has grown significantly. This has led to a need for devices that can efficiently and safely test cable faults. Over the past two decades, the use of long high-voltage cables, many of which have been installed and buried in water, has grown significantly. Down. This has led to a need for new technologies that can test these cables efficiently and safely.
The common methods of cable fault detectors (also called buried wire fault detectors) and their related techniques have been known for many years, but recently there has been a strong drive for further development. These include: The need to simplify the use of cable fault tester equipment to provide better guidance to operators through the cable fault tester process The need for equipment that can test cable feeders that are already in service, such as long cable runs for DC offshore use and longer AC cords. Technical considerations for cable fault tester manufacturers include: Longer cables, whether communication cables or DC cables, mean that more energy is stored in the cable through the cable fault tester process.
It is necessary to manage this energy safely. The physical properties of time domain reflectometry (TDR) meant that the methods and skills of the time were limited when working with long cables. TDR skills need to be optimized to minimize these constraints.
When working on high-voltage communication equipment with functions such as cross-connection, it is necessary to be able to adjust the filtering, triggering and bandwidth of TDR signal processing accordingly. Implement high-power technology for high-voltage cable testing and diagnostics, while ensuring that the equipment used for testing is easy to transport. . These considerations reflect the most common requests received from users of cable testing equipment. In addition, consideration was given to whether the feeder planning could be more cost-effective, in particular whether access to the junction box was required for protection or whether it could be buried and made inaccessible.
Looking for an easy way to use existing cable fault locator test methods and equipment for simple cable fault location without TDR capability. The primary reason for this was the desire to reduce setup time when switching between different test power sources and modes of operation, while maintaining operator safety. The preferred method is to produce a single unit that supports multiple cable fault tester technologies.
These reviews resulted in the development of a novel high-power cable fault location solution that facilitates rapid repair and protection. Cable fault tester manufacturer Shenzhen Noyafa Electronic Technology Co., Ltd.
