More Information
Summary:The present invention relates to an individualized self-monitoring system for transformers (31, 33) in a electric power measurement installation that comprises at least a transformer (31, 33) and at least a time-integrated electrical quantity meter (3, 4, 13), directly coupled to one of the windings of the transformer (31, 33), the meter (3, 4, 13) being capable of measuring and recording the electrical quantity of said winding. The present invention also relates to a method of monitoring and diagnosising transformers (31, 33) in a power measurement installation that comprises the steps of measuring the values of at least a directly measured time-integrated electrical in at least a winding of at least one transformer (31, 33), performing comparisons between the measured and generating diagnostic results with the compared data.
