Date(s): Jan 07, 2021 - Mar 25, 2021
Time:6:30 pm - 9:30 pm

Instructor: Ronald DeMarco

Course Description:

Covers reduction and solving for voltage, current or impedance in series and parallel circuits, differences between three-phase and one-phase distribution systems and layout of a vector diagram of the voltages in a three-phase wye and delta circuit. Also included is calculation of kva, kw and kvar in a three-phase system, law  of cosines, construction and operation of  meters, Construction  of a 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.

The successful passing of Classes 301-302 are prerequisites for registering for this class.
