Capacitive voltage transformer metering error situation awareness system

The invention discloses a capacitive voltage transformer metering error situation awareness system which comprises a data acquisition system, a data analysis system and a situation prediction system which are connected in sequence, and the data acquisition system acquires operating data of a CVT to be tested and an electric power system where the CVT to be tested is located in real time; accordingto the data acquired by the data acquisition system, the data analysis system analyzes the CVT metering error state; according to the CVT metering error state analyzed by the data analysis system, the situation prediction system predicts the CVT metering error situation. According to the sensing system, the problem of CVT metering errors can be found in time according to the situation of the CVTmetering errors, the CVT is overhauled in time, and therefore economic losses caused by the metering errors are avoided. According to the sensing system, the gradual change process of the CVT meteringabnormality can be calcula
