Remote Calibration System in Metering Device

With the continuous expansion of the grid size, the number of checkpoints metering device is also increased workload and difficulty inspectors also increasing, to carry out verification and monitoring of remote metering devices mark significant. Discusses the remote calibration and monitoring system principle, function and application metering device at checkpoints, and also describes the configuration and functions of the system back-office support software, scientifically demonstrated the remote meter error, PT secondary circuit drop, CT and secondary circuit admittance verification and monitoring of significance.
