Transformer Blast Pressures
Transformer Blast Pressures
(OP)
We have a project that has several high voltage mineral oil filled Transformers (138 kV, 16MVA typical size) that are located outdoors and are not enclosed. They are, however, separated by walls between the transformers.
I've done a search on the various threads in this forum and have not been able to determine/estimate design blast pressures for designing walls separating these transformers?
Does anyone have a good source for the magnitude of the pressures? I've checked IEEE and FM Global without success.
thanking you in advance,
Dik

RE: Transformer Blast Pressures
A more conservative approach would be to use walls that are earthquake rated as well as fire rated.
I realize that this doesn't answer your question, but I hope it helps.

That's what I've done with two previous projects... light steel frame, metal siding and rockwool insulation.
This client wants them designed for blast. Existing ones cantilever about 20' up and are 16"-18" reinforced concrete. He wants them to protect against 'blast'.
I've found reference to it in many locations including FM Global and IEEE, but cannot find any reference to exposions except one (sorta unrelated) article lists 20 psi and another lists 27 psi...
