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.

which circuit takes max. load & which circuit takes min. load i.e. SERIES CIRCUIT OR PARALLEL CIRCUIT??
