Of the ...big three... components of the electricity infrastructure, distribution typically gets the least attention, and no thorough, up-to-date treatment of the subject has been published in years. Filling that void, the Electric Power Distribution Handbook provides comprehensive information on the electrical aspects of power distribution systems. It is an unparalleled source for the background information, hard-to-find tables, graphs, methods, and statistics that power engineers need, and includes tips and solutions for problem solving and improving performance. In short, this handbook gives readers the tools they need to understand the science and practices of distribution systems.... Sensitivities (n = 33) Weak Link Overall Percentage Emergency off (EMO) circuit: pilot relay (33%), main contactor (14%) 47% dc power supplies: PC (7%), ... 10.9.2.1 Relays and Contactors Contactors are electromechanical switches used for a variety of power and control applications. ... Some of the most sensitive relays are small industrial relays with clear plastic cases referred to as ice-cube relays.
