| Abstract: | The applied circuit about the measurement for multiplex active energy was designed. A method for reducing ratio difference and angle difference of micro-transformer of current and micro-transformer of voltage is forward. The precision of active power is 0.5% through using micro-transformer of current and micro-transformer of voltage, and combining a circuit of microcomputer . The system of measurement about multiplex active energy has a good capability to get rid of electromagnetic interference. |
