Abstract :
A solution to the problem of objectionable voltage fluctuation in large industrial welders can be brought about by electronically interlocking each single phase welder with a dummy load to fill in the period of no load between welds; the load to be of suitable magnitude to keep the voltage variation within allowable limits. In addition, this method also results in considerable reduction in kilowatt-hour consumption of ballast load.
