A Remote On-line Detection System for Watt-hour Meter Based on Load Control Terminal

In order to improve the manage efficiency of operation and maintenance for electronic watt-hour meter,a remote on-line detection system for electronic watt-hour meter based on load control terminal is proposed in this paper.The upgrade design and application scheme of load control terminal is introduced,as well as the on-line detection method of electronic watt-hour meter under certain load conditions.In this paper,testing results of using electric energy impulses comparing with metering results of load control terminal and electronic watt-hour meter show that the system can detect whether the measurement performance of electronic watt-hour meter is in normal range,which has high detection accuracy.
