In order to strengthen the operation and maintenance work of equipment and data which are abnormal in the field of power system,a set of operation and maintenance management system of electric energy measurement equipment is designed to support the combination of on-site treatment of abnormal problems and planned patrol inspection.It relies on the existing measurement automation system and marketing system. At the same time, it can improve the automatic measurement system of power grid. In the paper, the new method of remote diagnosis is studied, which can realize the remote diagnosis of abnormal operation on site.The whole set of management system can guarantee the operation quality of metering equipment and improve the data collection integrity, correctness and operation. maintenance efficiency has been improved.
