Abstract :
This paper summarizes Bonneville Power Administration´s transformer short circuit test experience of three-phase units rated 115-kv Delta to 12.47-kv Wye; reviews BPA´s diagnostic and low voltage impulse test results, and correlates them with factory inspection of damaged units. Special emphasis is on the low voltage impulse method of evaluating transformer damage.
