transformer monitoring system used in indirect electricity metering system in an electricity metering facility and transformer monitoring and diagnostics method in an indirect electricity metering facility.

摘要

self-monitoring system for transformers in energy metering facilities and method of self-monitoring and diagnostics of transformers in energy metering facilities. The present invention relates to an individualized self-monitoring system for transformers (1,14) in an electrical metering facility arranged in an electrical distribution and / or transmission network for measuring electrical energy at a delivery point. and an electrical receiving point comprising at least one transformer (1, 14) and at least one time integrated electrical quantity meter (3, 4,13), coupled directly to one of the transformer terminals ( 1, 14), the meter (3, 4, 13) being able to measure and record this electrical quantity of said terminal. The present invention further relates to a method of self-monitoring and diagnostics of transformers (1,14) in an energy metering arrangement arranged in an electrical distribution and / or transmission network for measuring electrical energy at a energy delivery and an electrical receiving point comprising the steps of measuring values of a time-integrated electrical quantity directly in at least one winding of at least one transformer (1, 14), making comparisons between measured values and performing diagnostics based on the results of the comparisons.
