6 .6 Transformer Standards, Technical Data and Accessories Three-Phase How to Select Three-Phase Units 1. Determine the primary (source) voltage the voltage presently available.. Determine the secondary (load) voltage the voltage needed at the load. 3. Determine the load: If the load is defined in, a transformer can be selected from the tabulated data If the load rating is given in amperes, determine the load from the chart (below right). To determine when volts and amperes are known, use the formula: Volts Amperes 1.73 = If the load is an AC motor, determine the minimum transformer from the chart at the right Select a transformer rating equal to or greater than the load 4. Define tap arrangements needed. 5. Define temperature rise. Using the above procedure, select the transformer from the listings in this catalog. Three-Phase AC Motors Full Load Amperes Horsepower 08 Volts 30 Volts 380 Volts 460 Volts 575 Volts / Full Load Current in Amperes Three-Phase Circuits Minimum Transformer 1 Voltage If motors are started more than once per hour, increase minimum transformer by 0% When motor service factor is greater than 1, increase full load amperes proportionally. Example: If service factor is 1.15, increase above ampere values by 15% V-T-188 Volume Commercial Distribution CA E February 013
