Intelligent release is the core of intelligent low-voltage circuit breakers

Intelligent release is the core of intelligent low-voltage circuit breakers, not only has the general release of the various protection functions, but also has real-time parameter display, fault memory and queries, self-diagnostics, networking, communications and many other features. In the reviewed and summed up the development  air circuit breaker  release after  power transformers  the current smart appliances, especially the development trend of intelligent release is proposed based on DSP and CAN fieldbus intelligent release research direction. Paper discusses in detail the design  Electric transformer  of intelligent release from the electrical parameters of the sensor to the electrical parameters of the sampling method of calculating with intelligent release from a variety of protection features to achieve these protective properties of the mathematical model.
