What does the transformer rating depend upon?

The rating of a transformer solely depends upon the temperature rise. The better the cooling system in the transformer is, the better the transformer rating.

Transformer Ratings are Usually Expressed in Terms of A) volts B) kWh C) kVA D) kW

The transformer is specified with an apparent power rating (kVA or VA) instead of kW. The transformers are designed based on current and the voltage required for the transformer's operation. Therefore, the manufacturers pasted the details on the specification of it on the nameplate of the transformer in the form of VA (Volt-Amps). The specification of the Volt-Amps on the nameplate also denotes the rating of a transformer.

The rating of the transformer can also be considered the maximum current and voltage that can be safely applied to the transformer. The transformer current is used to calculate copper losses and the voltage for the iron losses.

The kVA rating is given to the transformer while expressing its power. The rating of a transformer solely depends upon the temperature rise. The temperature rise depends upon the transformer's losses. The proper cooling system maintains the transformer's temperature within permissible limits. The transformer's rating gets higher if its cooling system is effective and vice versa. Therefore, the cooling system's effectiveness plays a significant role in the transformer's rating.
