An automatic switching equipment for the control of two 20,000-kw. frequency changer sets using the Scherbius method of load and power factor control has been in successful operation at the Page Avenue station of the Union Electric Light and Power Company of St. Louis, for almost a year. This equipment contains several new features in the automatic control of machines of this type. Besides being the first completely automatic switching equipment applied to machines of this type, it is unique in… Expand
