ABSTRACT:
The present invention is directed to a method for determining actual tripping characteristics with the aid of a test apparatus in which test parameters are input with the aid of an input unit. The aim is to specify an appropriate method which works particularly quickly and precisely. This can be achieved when a theoretical tripping characteristic of the respective protective relay is stored in the test apparatus. Each measurement point of the actual tripping characteristic is determined on a locating straight line, the starting point for the measurement being a point of intersection of the locating straight line with the theoretical tripping characteristic. In this case, the locating straight line dissects the theoretical tripping characteristic at an angle. The angle is situated in a range from 60.degree. to 120.degree., 90.degree. being preferred.
