Introduction to Condition Monitoring of Transformer Insulation,purpose, the most important of which is the impulse voltage withstand test. Minor local defects in transformer insulation often manifest itself as partial discharges (PDs), which may cause catastrophic failure in the long run if allowed to continue unnoticed. Thus PD tests have emerged as one of the

Frequency Response Analysis, range to detect the deviations in the FRA response, with the help of which the nature of the mechanical fault as well as the quality of insulation could be judged. Frequency dependent parameters of winding such as inductances and capacitances determine the resonant frequencies which appear as peaks

Remaining Life Analysis, errors in life estimation. Temperature rise, oil condition, loading history, and design parameters are all key factors that determine the loss of life of a transformer through thermochemical degradation. Degree of polymerization (DP) of cellulose insulation is an excellent indicator of insulation a

Book 2013ty of effect..Many of the failure-management methods presented rely on the fact that most failures give warning when they are imminent. These potential failures give rise to identifiable physical conditions and the novel approaches described detect them so that action can be taken to avoid degenerat
