Substation basic is equipped with electric energy metering system, but the electric energy metering system does not have the energy metering run abnormal alarm function. This paper introduces a measuring equipment, using the existing data of electric energy metering system by expanding calculation, realize the on-line monitoring the operation of the energy metering, analyze the acquisition anomalies and equipment failure. And according to the requirements of the users, in order to handle in time measurement circuit fault subscribe to messages in the form of alarm and alarm, mail notification and page hint.
