Abstract
The trip curves of circuit protection devices in an electric power distribution system are individually adjusted and coordinated in a hierarchy of protection devices by graphical manipulation, such as by dragging with a mouse, segments of the trip curves presented on a display device. The existing parameter settings can be provided to the display device and the adjusted parameter settings returned to the protection devices manually, but preferably, a communications network provides automatic transfer of the settings in both directions.
