Communication on the Arkansas-Louisiana- Mississippi Interconnected System

This paper describes the communication facilities in use on the Arkansas, Louisiana and Mississippi Power & Light Companies´ interconnected system, and describes the operating performance of the communication equipment. Carrier-current telephone equipment is used to a large extent for relatively long distance communication, the longest distance being 459 miles. The reliability of this means of communication under unusual storm conditions is discussed. The experience resulting from over six years use of carrier-current telephony for load dispatching purposes is described.
