Electrical Maintenance

This eBook was written as the sequel to the eBook titled DC Circuits, which was written in 2016 by Chad Davis. This eBook covers Alternating Current (AC) circuit theory as well as a brief introduction of electronics. It is broken up into seven modules.

Welcome to the AC Electrical Circuit Analysis, an open educational resource (OER). The goal of this text is to introduce the theory and practical application of analysis of AC electrical circuits.

Capacitors and transient analysis of the capacitor charge and discharge process, inductors and transient analysis of the inductor storage and release process, sinusoidal properties, complex numbers, complex impedances, phasors, AC Ohm's Law, series AC circuit analysis, parallel AC circuit analysis, series-parallel AC circuit analysis.

Apparent, real, and reactive power, power factor, power factor correction, transformers, transformer connection diagrams, non=-ideal transformers, transformer efficiency, delta-y conversions involving complex impedances, AC current sources, AC source conversion, AC superposition theorem, AC Thevenin's theorem, AC maximum power transfer theorem, 3 phase AC systems, balanced and unbalanced 4 and 3 wire Y configurations, balanced and unbalanced delta configurations, single wattmeter method, two wattmeter method, phase sequence detection, and 3 phase AC power factor correction.
