APPARATUS AND METHOD FOR ADJUSTMENT AND COORDINATION OF CIRCUIT BREAKER TRIP CURVES THROUGH GRAPHICAL MANIPULATION

摘要

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.
