About Transformers. Transformer is a magnetic circuit used to step up or to step down voltage. Power transformers are transformers with a total banked capacity of more than 500 KVA and usually used to step up generation voltage to transmission or sub-transmission voltages, or step down transmission voltage to primary distribution voltage level. It is usually 3 phase banks and equipped with necessary devices for protection and monitoring. Distribution transformers, on the other hand, are usually used to step down primary distribution voltage to secondary distribution voltage level. Distribution transformers can either be single phase or three phase banks.
