Westinghouse Switch - Manual

The Operation and Maintenance Manual for Westinghouse’s Robonic Automatic Transfer Switches covers essential aspects of these critical electrical systems, including their design, operation, and troubleshooting. This manual outlines the key differences between Type A and Type B models, explaining how they manage power transfer via mechanical and automatic control mechanisms. It details component identification–such as voltage sensing relays, delay time relays, and solid-state or control relays–and provides technical specifications for their ratings, including interrupting capacity, withstand voltages, and protective device compatibility. The document also includes a troubleshooting guide for common power transfer issues, alongside maintenance recommendations to ensure reliable operation. Additionally, it addresses manual override procedures, safety precautions during installation and repairs, and the use of specialized tools like the Plant Exerciser for testing standby systems.
