Transformer Loading 101: A Comprehensive Guide for Energy …

Let''s assume that we have a transformer with a rating of 500 kVA and a load connected to it is drawing 400 kW of power. Transformer Loading (%) = (Load Power / Transformer Rating) x 100. Transformer Loading = (400 kW / 500 kVA) x 100 = 80%. Therefore, the transformer is operating at 80% of its rated capacity.

Transformer Ratings

The product of voltage and current is the apparent power or VA rating, and it is called the transformer rating. The designer considers the maximum VA of the transformer while designing. The transformer is specified for apparent power o r – VA. The transformer''s primary VA is equal to the secondary VA plus the losses in the transformer.
