JYL-KK type fault indicator
1.Advantages
The "energy module" which use the anti-corrosion and high-permeability material with low-power system design enables the battery-free full-function operation at a primary current of 5A;
Electronic current transformer for current and ground electric field detection, It has great linearity of test data and is not affected by wire diameter, thus guarantee test accuracy;
The three-level power architecture (CT power supply, supercapacitor, and disposable lithium battery) constitutes the power supply system let the equipment operates 24/7;
4k sampling and zero sequence synthesis algorithm, Highly sensitive detection and recording of single-phase ground faults;
Three-phase synchronization technology, the time error is less than 100us;
Both the collection unit and the acquisition unit can be controlled remotely and wirelessly;
