One of our customers is served from a 2500 kVA PMT, 5-legged, 35 kV Gnd Wye - 480V Gnd Wye. The 35 kV feed is from a fused Overhead lateral line to a fused terminal pole. The cable from the TP to the transformer is about 100' 1/0 AL EPR cable. The customer has a transfer switch that senses...
Does any IEEE/ANSI transformer standard state the minimum thickness of a pad mounted transformer tank? Or is any thickness acceptable AS LONG AS the transformer tank meets the pressure withstand requirements?
A customer recently requested primary service from our 35 kV totally underground distribution system. At this voltage our standard connection is solidly grounded wye-grounded wye transformers to reduce the risk of ferroresonance. The customer already has a 2500 kVA, delta (35kV side)-grounded...
