Evaluation of Control and Protection Circuits.
NTIS: PB/82-105065 :50 pages
Solid-state equipment offers a number of potential advantages in the coal mining industry. These advantages can only be realized, however, through careful and judicious design of the control and protection circuitry. Problems relating to the interaction of solid- state equipment on the electrical system and the special design considerations that apply to solid-state circuitry are examined. Design guidelines are provided for solid-state applications in the areas of (1) equipment operated from a DC trolley wire, (2) drive systems for surface mining equipment, (3) ac motor starters, and (4) electromagnetic interference.
