Abstract :
Internal fault detection in transformers, provides early warning of electrical failure and could prevent forced outages with the consequential costs. To detect and diagnose transformer internal faults is required a model. This paper presents simulations of the models developed on its companion paper. The models are no fault, fault among turns, winding to earth fault and aging.
