The handbook is designed to bridge the gap between theoretical electrical engineering and practical application. Its primary focus areas include:
Without a reliable control power source (often DC battery banks), switchgear cannot operate during a blackout. The handbook provides wiring diagrams and logic for and interlocking schemes that prevent dangerous switching errors. 4. Protection Relays and Automation
Switchgear and Control Handbook by Robert W. Smeaton | Hardcover switchgear and control handbook
Focuses on industrial switchgear, batteries, substations, and low-voltage DC switchgear. Part III: Motor Control and Protective Devices:
Switchgear is strictly categorized by the voltage levels it is engineered to handle. Low Voltage (LV) Switchgear Up to 1,000V AC. The handbook is designed to bridge the gap
: Managing power flow by starting, stopping, and regulating equipment. Technical Classifications
: Integration of ANSI/NEMA design standards and other industry recommended practices. Context in Electrical Literature Part III: Motor Control and Protective Devices: Switchgear
Where this book shines is in its application guidance. It doesn't just describe a circuit breaker; it describes how to apply it to a bus tie, a feeder, or a generator circuit. It discusses the nuances of short-circuit duties, transient recovery voltage, and the physical layout of substations in a way that modern standards (IEEE/IEC) often assume you already know.
One of the most cited foundational resources is the edited by Robert W. Smeaton, which provides a broad overview of design, application, safety, and maintenance. First published in 1977 and later updated in 1987, it includes key topics like AC and DC low-voltage switchgear, system protection and coordination, variable-frequency drives, and busway distribution.
This comprehensive guide serves as an unofficial handbook to the principles, types, components, and applications of switchgear and control technology, serving the needs of electrical engineers, technicians, and facility managers in 2026. 1. What is Switchgear?
Traditional design requiring more physical footprint. High-Voltage (HV) Switchgear (75KV and Above)
