Planning a 13,800-volt subtransmission system

SYSTEM STUDIES are generally thought to be the engineering analysis and planning that are done in connection with the operation and expansion of large transmission or interconnected power systems. Distribution systems, particularly systems serving rural areas, often develop haphazardly in response to requests for service from prospective customers with little or no thought being given to over-all planning for the system. The system to be described developed in this manner until an increasing number of complaints of poor service from the customers being served made it obvious that some study would have to be given the system.
