- Abstract
Designed in this paper, the energy-saving electronic 10kV metering device is composed of electronic voltage transformer, electronic current transformer, electronic metering terminal and communication terminal. Electronic transformers and metering terminal are no longer designed and tested independently. Based on the principle of minimum overall error of 10kV electricity metering device, the partial pressure ratio of 10kV volt-age divider network, the ratio of electronic current transformer and current-voltage conversion, the influence of the stray capacitance generated after electronic transformer and metering terminal are packaged in the circuit breaker box, should be coordinated in integrated design consideration, based on input range and calibration capability of measurement chip. And the 10kV metering device is tested with integration method. This article describes the device structures and calibrating methods. The test results show that the active power accuracy class of the device designed in this paper is 0.5, and that reactive power accuracy class is 2.0. The developed device with low power consumption advantages and three-phase four-wire connection mode, resolved line loss problem due to the unbalanced load.
