Problems solved by technology

However, these testing techniques have not been widely promoted. The reason is that when using the above-mentioned equipment for live testing, it is necessary to connect testing equipment such as dielectric loss testers, partial discharge detectors, or ultra-high frequency partial discharge detectors. These detection equipment need to be operated in a power failure, which brings inconvenience to the installation and also brings certain economic losses.
In addition, installing terminal boxes or connecting sensors on existing equipment will affect equipment reliability and cause potential safety hazards
