Sažetak

Introduced in 2017, the extraction of exciting current components opens the door for a further enhancement of electromagnetic circuits’ diagnostics. Traditionally, analysis of single-phase exciting current and loss data relies on total current, loss and power factor. For some transformers,
the prominence of the capacitive current component masks the behaviour of the inductive component, yielding to uncertainties of the diagnostic criteria. The method allows the separation of the essential constituents of the total measured current and the report of all three, namely, IR, IL and IC components. This article describes the method and its diagnostic advantages.
