These transformers are rated 250 kVA and smaller with high voltages of 34 500 GrdY/19 920 V and below and with low voltages of 480/240 V and be low. These transformers are generally used for step-down purposes from an underground primary cable supply. The connector, bushing, and terminal arrangements for radial or loop feed systems are covered in this standard. The electrical and mechanical requirements of any accessory devices that may be supplied with the transformer are not covered in this standard.Electric transformersElectric transformers.621.314WaSeSSWaSeSSDOCUMENT996280647003316IEEE standard for pad-mounted-type, self-cooled, single-phase distribution transformers 250 kVA and smaller2806133UNISA
