Contributions Concerning the Clock Hour Figure Utilization for the Power Transformer Diagnostic
Journal Title: Analele Universitatii "Eftimie Murgu" Resita. Fascicula de Inginerie - Year 2014, Vol 21, Issue 2
Abstract
The paper is based on a study for the diagnosis of power transformer through the signal configuration that are part of the clock hour figure code for a defect transformer. The investigations made have the purpose to compare the code signal before and after the transformers damage. The comparative analyzes of the signal form, course and polarity are constituted in diagnosis criteria and are formulated the conclusion about the defect location, nature and dimension.
