Abstracts
Part 1 of this article, published in Volume 3 Issue 4, pages 100ff, describes the measurements of excitation, winding resistance, turns ratio and accuracy as the most common diagnostic measurements on instrument transformers (current and voltage transformers) for condition and reliability assessment. Case studies show the failures which can be derived from the results and underline the importance of conducting regular diagnostic tests. Part 2 gives more details about the measurements of capacitance and dissipation/power factor, short circuit impedance, dielectric response analysis and partial discharge.
