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 singlephase AC circuit. Calculates power factor, given true power and apparent power.
ThreePhase Power– 12 minutes Defines threephase power. Explains how singlephase power and the square root of 3 are related to threephase power. Calculates true power in a threephase system. Lists some of the advantages a threephase system offers over a singlephase system.
Delta and Wye Configurations – 12 minutes Draws a simplified electrical diagram of a deltaconfigured transformer and a wyeconfigured transformer. Explains how a deltaconfigured transformer and a wyeconfigured transformer affect current and voltage in a threephase distribution system. Lists some common applications for delta and wyeconnected transformers in a threephase distribution system.
Voltage Regulator Applications– 12 minutes Describes the function of a voltage regulator in a distribution system. Explains how a step voltage regulator and an induction voltage regulator operate, and how they affect voltage in a distribution system.
Capacitor Applications– 8 minutes Describes how capacitor banks are connected into a distribution system. Explains how capacitor banks adjust power factor.
