The Applied Research Of Current Sensor In Electrical Equipment Of Chemical Plant

Current is one basic parameter. Current measurement is not only important for itself ,but also other parameter can transform to current by convertor. So Current measurement is the basic of Electromagnetic surveying.Current sensor may be defined as following: Current sensor is one measuring equipment converts electric current from one kind to another , at some accuracy and some coincidence relation.Current sensor can be classified into two categories: Traditional Current sensor and Modern Current sensor.Traditional Current sensor is current transformer, which can be classified into two categories: used in surveying and relay protection. Current transformer can supply standard signal fit for intelligent instrument, working with Current convertor togetherModern Current sensor include Hall Current sensor, Optoelectronic Current sensor and Rogowski Current sensor etc.In comparison with Traditional Current sensor, Modern Current sensor has no saturation, wider transmission frequency bandwidth, better anti-interference ability, lighter...
