The energy metering box is an important device to ensure the safe and stable operation of the energy metering device. Its quality directly affects the corporate image of the State Grid Corporation and the safety of electricity used by thousands of households. The gray state clustering operation state evaluation scheme is proposed, and the measurement box fault factor is further analyzed to provide a theoretical basis for improving the production process and improving product quality. The evaluation technology of the operation status of the metering box is proposed, and the gray-weighted multi-index comprehensive operation status evaluation scheme of the metering box is formed, and the quality control of the energy metering box is improved.
