    2017-5-23u2002·u2002Quote (charz) 1. In voltage drop calculations the Voltage drop equation is IR Cos (phi) + IX Sin (phi). What is phi here? Phi - Power factor angle of the load. (or) Phi - Internal Impedance angle of the transformer (arc tan (X/R)) where X/R is the X/R of the transformer. 2. For example, In cable size adequacy check, Phi is the load power factor ...
