Secondary Versus Primary Capacitors

Secondary capacitors cost more than primary capacitors but they offer some additional benefits which may offset the additional costs. There are presented herein the results of a comprehensive economic study covering a wide variety of circuit and load conditions on both network and radial distribution systems to establish within reasonable limits the probable field of application of the secondary capacitor. From the results of the study it appears that secondary capacitors can be justified in practically all cases on secondary networks but have a limited application on primary radial distribution systems.
