Individualized System of self-monitoring for Transformers in Energy Metering facilities and self diagnosis method and facilities of Transformers in Power Measurement

摘要

The system comprises: (i) at least one Transformer connected to a Distribution Point and / or transmission of Energy; and (ii) at least one meter of an electric Unit integrated in time directly coupled to one of the terminals of the Transformer or meters, being able d And to measure and record the Electric Unit of the terminal.In addition, the method includes the following steps: a) measured values of an electric Unit integrated in time directly in the winding of the Transformer; (b) comparisons between values measured in the same Unit taken in different Electric Terminals of a Transformer; (c) gene Results of the Comparisons was,Includes calculating the angular difference between the primary current and Secondary current of a Transformer; and (d) diagnosis based on the results of comparisons
