SINGLE/THREE PHASE POWER FUNDAMENTALS 
Single/Three-phase power principles involving true power (watts), reactive power (volt-amps reactive), and apparent power (volt-amps). Power factor with respect to various load types will be analyzed. The sizing of a capacitor-bank to achieve unity power factor will be calculated along with the transformer sizing in KVA based on the load being served.

A discussion of transformer types, construction, and operation will be presented. The transformer "turns-ratio" will be applied to find the primary/secondary voltages and currents. The relationship between line and phase voltages and currents will be explained with respect to three-phase delta and wye configurations. Harmonics will be defined and analyzed.

A hands-on lab will measure line/phase voltage and current.
