vector group of transformer-Three phase transformer consists of three sets of primary windings, one for each phase, and three sets of secondary windings wound on the same iron core.load hormonics-Harmonic voltages and currents in an electric power system are a result of non-linear electric loads. Harmonic frequencies in the power grid are a frequent cause of power quality problems. Harmonics in power systems result in increased heating in the equipment and conductors, misfiring in variable speed drives, and torque pulsations in motors. Reduction of harmonics is considered desirable.

There is 3phase power cable from 1 point to the other point which is 100m away. Two point equipped with power meter and recorded 1st point is 205kW while the 2nd is 202kW and each phase average carry 400amps. To calculate the resistance of the 3phase power cable, is the formula using will be P=I2R?
