Implementation of a High Speed, Heavy Current, DC Switching System.
NTIS: PB 283 388 Available for Reference At Bureau Libraries :77 pages
Laboratory performance of mercury-filled current limiting devices (cld) used for high speed switching of direct current circuits (66 volts and below, up to 1,000 amperes) using a system involving a parallel connected vacuum switch with cld and an additional series connected vacuum switch was verified. This report details analytical work and field experimental tests to predict and control voltage surges associated with the high switching speed associated with the switching system. It also details tests conducted to demonstrate the fault current limiting ability of the cld. Problems associated with designing a fault current limiting system are discussed.
