High-Voltage AC Power 2 - Videos and Related Books



This 54-minute video explains basic AC power theory. It focuses on the relationships between various types of power and on the functions of transformers, voltage regulators, and capacitors in a distribution system. Defines apparent power, true power, reactive power, and power factor and explains the meaning of each term in the context of three-phase AC distribution systems. Describes how delta and wye configurations affect voltage and current and how voltage regulators and capacitors are used to affect the power factor in a three-phase distribution system.

Training Sessions

Power – 9 minutes
Defines power in terms of voltage and current. Defines the terms apparent power, true power, and reactive power. Describes the relationships between apparent power, true power, reactive power, and power factor in a single-phase AC circuit. Calculates power factor, given true power and apparent power.

Three-Phase Power – 12 minutes
