Zusammenfassung:This paper proposes a low cost power parameter monitor based on PIC16F877A. It is developed as a low cost alternative for power quality analyzers. The device measures voltage and current in three phase supply and display the power parameters like RMS voltage, RMS current, active power, reactive power, apparent power, power factor, harmonics(THD). To measure voltages and currents from power distribution lines signal conditioning circuits are used and to display the power parameters a 2 times 16 LCD display is used. By using RS232 interface data can be transmitted to the computer system and it can be used for further analysis. To handle more number of data during processes using I2C serial EEPROM increases memory.
