The application of the saturated-core reactor and regulator

The purpose of this paper is to state briefly the use of voltage regulators and reactors in transmission and distribution systems and to mention operating requirements which might be best met by the use of saturated-core type regulators or reactors. The saturated-core type regulator and reactor consists of an iron core with two sets of coils. One set of coils is connected to a d-c. circuit and the other set to an a-c. circuit. The theory, design and construction of the saturated-core type regulator and reactor is discussed in A. Boyajian's paper.
