WebHow to Size and Select a Transformer 1. Go to “How to size a transformer” on page 1.3 to determine the proper KVA based on the required load voltage, line voltage and load current. For an examplelet’s use Load voltage = 480 volts, Load current, = 80 Amps and Line voltage = 208 volts. Using the calculation yields a 66 KVA transformer. 2. WebDec 18, 2024 · Industry standard sizes for 480- to 120/208-volt wye transformers are commonly 15, 30, 45, 75, 112.5, 225, 300 and 500 kilovolt-amperes. There are also single-phase 277-or 480-volt transformer sizes available at 5, 7.5, 10, 15, 25, 37.5, 50, 75 and 100 kilovolt-amperes.
