AC Circuits and Power Distribution

These flashcards cover key vocabulary and concepts related to AC circuits, power distribution, and motor systems based on lecture notes.

AC Circuit

A circuit that is energized using an alternating source, where the magnitude and direction of current and voltages change regularly.

Alternating Current (AC)

Electric current that reverses its direction periodically.

Star Connection

A method of connecting the end of coils in common in a three-phase electrical system.

Phases (in electrical systems)

Refers to the separate alternating currents that are phase-shifted to work together, typically represented as R, Y, and B.

Generator Stator

The stationary part of a generator that creates a magnetic field for power generation.

Load Distribution

The process of distributing electrical power among various consumers or systems.

Motor Rating

Specifications that detail the operational output and efficiency of a motor.

Electrical Efficiency (Effcy)

A measure of how effectively the input power is converted into useful output power in a system.

Dimetrically Opposite Coils

Coils in a generator stator configuration that are spaced evenly across the magnetic field.

Salient Poles

Poles that stick out from the surface of a stator, often used in the construction of generators.
