Design of Automatic Recording Instrument for Power Factor

Hongen Liu

Abstract

The interface circuit for measuring the voltage and current phase of power network is designed. The measurement principle of the power factor is analyzed. The hardware and software design methods based on the microprocessor AT89S51 are put forward. Practical applications show this instrument has realized digital display and automatic record for the power factor.
