| Abstract: | Air circuit-breakers and molded case circuit-breakers have been largely applied in low-voltage auxiliary power system of power plants. How to set the pickup of trip devices for full coordination between mains, feeders and branches is still a problem for technologist. An example will be shown in the article and several problems will be mentioned to be paid attention to in the process of pickup setting and coordination arrangement. |
