Abstract :
The continuing expansion and modernization program in the cement industry has placed an increasing importance on the cement plant power distribution system. The use of fewer larger production units and the increased use of automatic controls has placed greater stress on the adequacy and reliability of the power system. Safety, capacity, reliability, and low maintenance, all at a reasonable cost, are the requirements of the plant power system. The Distribution Working Group of the IEEE Cement Industry Committee was formed in 1959 in order to establish recommended practices for the cement industry to realize these requirements. The first Working Group Report was presented as an IEEE Conference Paper in 1960 and, since then, has undergone annual revisions. The Report now includes recommendations on the plant substation, main plant power distribution, relaying, metering, cables, and quarry distribution.
