Eastern Center for Arts and Technology

Covers reduction and solving for voltage, current or impedance in serices and parallel circuitys, differences between three-phase and one-phase distribution systems and layout of vector diagram of the voltages in three-phase wye and delta circuit. Also included is calculation of kva, kw andkvar in a three-phase system, law of consines, construction and operation of meters. Construction of a three-phase motor and principles of a tshree-phase rotating magnetic field.  Step-down/step-up transformers, exitation current, efficiency amp-turns, primary to secondary winding voltage and current ratios are covered.
