9781334216138: A Laboratory Manual of Alternating Currents (Classic Reprint)

Synopsis

Explore hands-on tests and measurements for transformers, motors, and polyphase systems.

This laboratory-style guide leads you through practical experiments, oscilloscope traces, and vector diagrams to illuminate how electrical machines respond to different loads and field conditions. It emphasizes real-world measurement, interpretation, and the relationships between current, voltage, and electromagnetic forces.

  • Learn how to observe and interpret current and voltage waveforms in single-phase and polyphase machines.
  • See how armature reaction, field excitation, and load affect waveforms and harmonics.
  • Build and analyze vector diagrams of EMFs and currents to predict performance and regulation.
  • Explore the behavior of transformers in parallel operation and the distribution of load between units.
Ideal for students and technicians needing practical grounding in electrical machines and their behavior in real circuits.
