Distribution transformer dimensioning
Distribution transformer dimensioning
(OP)
Hi there.
Electric power utilities often design their distribution transformer for the peak loading amps even though this conditions only appear few times a year for a very short period (few hours). In fact Christmas evening is sometimes used as reference for maximum transformer loading.
However is this really the right way to do it because the loading of the transformer varies considerably within a day and the average loading could be even less than 50%.
Anyone who knows how to find any litterature about this topic ?

The distribution transformer loading criteria needs to be adjusted for load types and ambient conditions for each region. The 'Christmas' generalization isn't very useful.
