Sažetak
A new criterion is proposed for the determination of the necessary duration of transformer temperature rise tests. The new criterion and the extrapolation of only those measured points that lie above 60% of the steady-state temperature rise ensure a higher accuracy of determination of steady-state oil and winding temperature rises, independently of the transformer thermal time constant.
