Sažetak
The analysis of temperature rise tests of "inverted" current transformers shows that the meassurements performed in accordance with the existing standards do not provide accurate determination of steady-state temperature rises. The errors increase with the increase of transformer thermal time constant, and can exceed even 40 K! Therefore, a new, more accurate method for determination of steady-state temperature rises of instrument transformers is proposed.
