Leak Current Detector and Breaker    

A break-through technology to detect true leakage that solves the problems of traditional current leak detection technology.


The technology detects true current leakage without being influenced by noise, harmonic, surge current and capacitance factors. Traditional current leak detection technologies have weakness and problems such as "it detects and operates without any actual leakage", "it does not detect leakage when it occurs", "it cannot specify points of leakge" and "slow in speed to detect". This technology solves these problems by the Vector Theory Igr Method, and can be easily developed into an IC chip.

Primary Application of the Technology

Leakage current breaker market,
Leakage detection market

The Problem Solved by the Technology

The current "Io System" is suitalbe for the old-fashioned technology in 1960s, when PC or on-line power systems didn't exist. It has disadvantages because it does not detect leakage when it occurs, or it cannot specify points of leakage, or if the detection speed is low. This technology can achieve highly accurate leak detection, enhanced speed to detect leakage and an ability to measure leakage while equipment is operating to solve these problems.
