ELE 303 TRANSFORMERES AND POLYPHASE
with Ron DeMarco
$345
Covers reduction and solving for voltage, current or impedance in series and paralel circuits, differences between three-phase and one-phase distribution systems and layout of vector diagram of the voltages in a three-phase wye and delta circuit. Also included is calculation of kva, kw and kyar in three-phase system, law of cosines, construction and operation of meters, construction of three-phase motor and principles of a three-phase rotating magnetic field. step-down/step-up transformers, excitation current, efficiency, amp-turns, primary to secondary winding voltage and current ratios are covered
