Move from electrical theory into calculations used around real equipment.Transformers, Motors & Electrical Calculations is Book 3 of the Electrical Trades Learning Series. Topics include transformer ratios and kVA, single-phase and three-phase calculations, motor calculations, voltage drop, conductor ampacity, and adjustment and correction.A practical field-tester reference introduces common instruments electricians may reach for when troubleshooting motors and transformers, including multimeters, clamp meters, insulation-resistance testers, phase-rotation testers, winding-resistance equipment, transformer turns-ratio testers, and motor circuit analyzers.Worked examples, diagrams, field-oriented problems, nameplate exercises, troubleshooting references, and 2026 NEC-based calculation practice help connect classroom math to real electrical equipment.
