32+ Why Transformer Rating In Kvar Pictures. Explained why transformer rating is in kva ?briefly explained about transformer and different types of losses in transformers. Manufacturers design transformers based on the voltage and current required for the transformer's operation.
Why Transformer Rated In Kva Not In Kw Electrical Technology from www.electricaltechnology.org The transformer is rated in kva and not in kw. There are two reasons because of which the rating of the transformer is in kva. Copper losses ( i²r)depends on current which passing through transformer winding while iron losses or core losses or insulation losses depends on voltage.
Transformer rating is expressed in kva, not in kw.
Let understand this in details. Transformers are rated in kva or mva. This temperature is dictated by the amount of current flowing. By doing so we can eliminate the confusions regarding the type of load being connected.
