I am specifying/installing (4) 3MVA transformers that are to be located outside in the US in a hot/tropical climate (HI). It needs to be as close to the building as allowable and each other. I am looking for a guideline/standard on placing outdoor transformers. The NEC only mentions providing adequate ventillation for transformers.
I found this in IEEE C57.12.01 - 4.1.2 Temperature
The temperature of the cooling air (ambient temperature) shall not exceed 40 ºC, and the average
temperature of the cooling air for any 24-hour period shall not exceed 30 ºC.
The minimum ambient temperature shall not be lower than –30 ºC.
Does anybody know of any other standards or guidelines for installing these?
The team wants to place them right by the building and next to each other and need some help figuring this out.
Thanks.
