Abstract
The invention relates to an electric circuit arrangement () for the functional testing of a monitoring device () for a power supply system (), the electric circuit arrangement () having a test resistance (R, R) which is switched between an active conductor (L, L) of the power supply system () and ground (PE) and has a settable actual resistance value (R). In this context, a bidirectional cascade () consisting of field-effect transistors as test resistances (R, R) and an analog control () for the continuous-value setting of the actual resistance value (R) to a predefined target resistance value (R) are provided. Furthermore, the invention relates to a modular circuit arrangement () consisting of several electric circuit arrangements () according to the invention, each of the electric circuit arrangements () being assigned a different active conductor (L, L) of the electric power supply system (), and a central control unit () being implemented for controlling and monitoring the electric circuit arrangements ().
