DOE Fundamentals Handbook Electrical Science (June 1992)

Published by the U.S. Department of Energy. Volume 2, DOE-HDBK-1011/2-92: Module 5, DC Generators, and Module 6, DC Motors; Module 6, DC Motor Theory, describes induced opposing electric potential difference and torque. Volume 3, DOE-HDBK-1011/3-92: Module 7, AC Generation Analysis, printed pp. 4–7, especially effective values and equations 7-1–7-8; Module 9, AC Power. Volume 4, DOE-HDBK-1011/4-92: Module 13, Transformer Theory, especially copper loss and efficiency on printed pp. 11–13; Module 15, System Components and Protection Devices, printed pp. 1–6 and Figure 1, followed by Wiring Schemes and Grounding.

Volume 3, Module 8, Resonance, printed p. 19: equation 8-14 gives the resonant frequency, and Series Resonance states that the net series reactance vanishes and the current is set by the remaining resistance. ^[ref]

Volume 3, Module 10, AC Generator Theory, printed p. 6, equation 10-1, gives generated frequency from rotor speed in revolutions per minute and total magnetic pole count. Volume 2, Module 6, DC Motor Theory, printed pp. 4–6, equations 6-1–6-3, relates electromagnetic torque, opposing induced electric potential difference and armature current.

Volume 4, Module 13, Transformer Types, printed p. 19, Instrument Current Transformer, describes the many-secondary-turn measurement arrangement and the physical reason an energized open secondary can develop excessive induced electric potential difference.
