Moisture in oil-paper insulation acts as a catalyst in transformer insulation deterioration and accelerates ageing. Thus it is crucial to detect accurately the presence of moisture within oil and paper insulation early as to avoid any pre-mature failures. Reliability of power transformers depends on...
