Why Is A Transformer Rated In KVA But Not In KW?

Why Is A Transformer Rated In KVA?

The fundamental reason that all AC sources (transformers or alternators) are rated in VA (or KVA or MVA) is that the load attached determines the current power factor. Because the load power factor is unknown (during the transformer manufacturing process), they are rated for resistive loads (PF = 1). Furthermore, why are transformers rated in…
