Aiming at current real-time monitoring problem in alternating and direct current power circuit
a power monitoring system based on Hall current sensor is designed. Based on Hall compensation principle
current sensor CSNE151—100 in system converts measured current to linear voltage signal. Digital signal processor( DSP) in system collects measured value from current sensor and achieve overcurrent protection of power by controlling switch. The system is tested in labs
experimental results show that the designed power monitoring system has fast response speed and high measurement precision. It has been applied in engineering practice
and works reliably and stably and has good practical value.
