Abstract :
The ability of a 2,300-4,000-volt distribution system to supply single-phase a-c welders is limited not only by current-carrying capacity, but also by voltage regulation. The voltage limitations are reviewed and methods suggested for increasing the limits by changes in the power system and the customers´ installations. Three types of subtransmission connections are described for use when the welding load outgrows the distribution power supply.
