Product Introduction


Be the first to apply Roche coils into this type of indicator, It has great linearity of test data and is not affected by wire diameter, thus guarantee test accuracy;
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 2A;
The three-level power architecture (CT power supply, supercapacitor, and disposable lithium battery) constitutes the power supply system let the equipment operates 24/7;
High-protection level "collection unit", withstands temperature shocks and long-term blisters, ensuring long-term outdoor working reliability;
Both the collection unit and the acquisition unit can be controlled remotely and wirelessly;



Responsibility: Production research and development MV& LV switch , outdoor&indoor VCB, power distribution terminals (DTU, FTU).
