Operating Experience with the Low-Voltage A-C. Network in Cincinnati

This paper describes briefly the operating experience and problems which have resulted from the installation of a four-wire, 120/208-volt secondary network system with combined light and power mains. The problems with reference to network equipment, voltage regulation, and operation of consumers´ equipment are stated with their subsequent solution. The results obtained from fifteen months operation of this system indicate that, with reasonable care in layout and selection of equipment, no operating problems of major importance will be met.
