Intermediate/Advanced Electrical Theory - 31-Lesson Professional Training Course

Intermediate/Advanced Electrical Theory is the follow-up to Electrical Fundamentals for Beginners, built for readers ready to move past basic concepts into professional-level electrical theory.Across 6 modules and 31 lessons, it covers AC circuit analysis (RMS values, impedance, reactance, resonance), power engineering (power factor, three-phase power, harmonics), advanced motor theory (VFDs, soft starters, motor efficiency), protection and coordination (time-current curves, ground fault protection, arc flash awareness), electrical distribution systems, and practical advanced diagnostic skills like oscilloscope use and insulation resistance testing.Each lesson pairs a clear explanation with a visual breakdown of the underlying theory, a practical case study, and a short knowledge check — aimed at building genuine, connected understanding rather than isolated facts.Written by Aamir Shahzad, Senior Deputy Manager – Instrumentation & Control at Gharibwal Cement, drawing on over 25 years of hands-on field experience.
