SIGRADE is a software program for overcurrent protection coordination for high, medium and low voltage networks. It allows the selection of grading paths and the drawing tripping characteristics of fuses and protection relays into a log-log current-time diagram.
SIGRADE guides the user from an initial simple sketch of the project through the collected information and data to short-circuit calculations, supports the user in developing a protection concept and documents the complete relay coordination of overcurrent protection devices.
