Assuming an ideal transformer, determine (a) the primary and secondary full-load currents, (b) the transformer turns ratio. a) V 1 = 4000 V, V 2 = 400 V, Transformer Rating = 50 kVA = V 1 × I 1 = V 2 × I 2. Primary full-load current, I 1 = (50 × 1000 / ...Transformer calculator HOW TO SIZE A TRANSFORMER. Transformers are sized by determining the total load required (in amps). Transformer capacity is rated in KVA (kilo-volt-amperes). The load voltage and load amps must be known to calculate KVA rating. * NOTE: We do not recommend loading a transformer above 80% of its KVA rating.

Retired PV System Designer. Dec 17, 2014. #9. If you have transformers designed for 120/240 input and less than 480V output, they will do you no good, since you cannot connect them to 480V. Now with isolation type three phase transformers you cannot necessarily construct a boost configuration, depending on the configuration of the output windings.Feb 21, 2012 · The fact that the transformer is a wye is of no consequence. The voltage across any coil will not exceed 208, and the voltage from any point in any coil will not exceed 120 to ground. Think of a wye wound 3ø motor. The center of the wye is isolated from ground, just as it should be with a wye wound transformer. Wiring a Transformer backwards. I have120/208 at my Jobsite.

As to (1): If you elect to increase your primary breaker to 250 amps, beyond the 125%, then your transformer secondary must be protected at 125% of the rated current. What matters is only the total KVA of the loads. If your mission is to match a transformer size to the rating of a 200 amp panel, you get there by multiplying 200 amps times 208 volts times 1.732. That result is 72 KVA. Even if you allow for the short time overloading of a 45 kva transformer to a level of 125%, it would still only give you 56 KVA.A 480 delta primary — 240 delta secondary transformer may be used on a 4 wire, 480Y/277 volt supply. ... primary of 480V delta and secondary of 208Y/120 V.
