Station Service Transformer
Station Service Transformer
(OP)
It is difficult to calculate the needed size of a station service transformer because actual loads vary and can be smaller than the rated size. There is also diversity of loads, since not all loads are on at the same time. The total load for the station is 179.3kVA. The power winding is rated for 100kVA. Does this mean I need a second station service transformer? Maybe, but again the entire load would not be on at the same time. I cannot find an applicable NEC or IEEE code for this. If I cannot, it will be difficult to justify the additional expense under my current project. Any ideas...

RE: Station Service Transformer
From where you are feed this station transformer?
What is a type of load?
What part of load is critical for station?
This part of Q's , what you need ask for decide something

RE: Station Service Transformer
Connected load is almost always greater than the peak demand load, sometimes much greater.
You might take a look at the IEEE Red Book and/or Grey Book from some help with load calculations.
