The 1.73 is the square root of the number 3 for the three phases. In order to determine missing values of efficiency and/or power factor, the formula is the same as for single-phase except the 1.73 is included in the calculation. Three-phase (Percent Efficiency/PF) = hp x 746/E x I x 1.73 Use this formula just like the single-phase version.
