Electromagnetic current transformer measuring and monitoring large current

For the current power system using electromagnetic current transformer measuring and monitoring of the existence of a large current issues related to study design of a fiber-optic  mcb circuit breaker  pressure differential current sensor. Based on Faraday effect and hybrid fiber current sensor research program compared to the high-pressure side of the system to take away the power and resolve optical properties affected by  electric meter  serious difficulties. Transformation of high current through the coil wound on the amount of voltage to modulate the piezoelectric ceramic fiber optical  electri cenergy meter  detected by the differential phase variation amount. Simple structure, large dynamic range, on the outside slow variables (such as temperature) is not sensitive to impact.
