System and method for measuring voltage and current and correcting errors in high voltage power system

摘要

PURPOSE: A system and a method for measuring a voltage and a current and correcting error in a high voltage power system using a wireless communication between a measuring unit and a comparator are provided to verify the measurement precision of the voltage and the current by compensating the error between a wiring device and a terminal. CONSTITUTION: A measuring unit(100) measures the voltage and the current of a high voltage system. The effective value of the measured voltage and current and phase are transmitted to a comparator(300). A terminal(200) measures the voltage and the current of a distribution device and calculates a power factor based on the measured voltage and current. The effective value of the voltage and current and the power factor are transmitted to the comparator. The comparator calculates the value for compensating the error from the voltage, current and the power factor.
