Passively-measuring circuit arrangement for e.g. ground fault monitor in actuator sensor interface-sensor-actuator-network, has modulator controlled by subscriber, where fault degree between signals is determined by current measurement

摘要

The arrangement has an inductive modulator controlled by an active subscriber e.g. master or slave, and designed as a current-voltage converter or data coupler (9). An alternating current-alternating current-induction current converter is arranged at a right side of a resistor-inductor network, where actuator sensor interface (ASI)-alternating current based unbalance and/or ground fault degree between ASI-alternating current signals is determined by ASI-high frequency-difference current measurement between ASI-network-lines and displayed as analog measuring signal output. An independent claim is also included for a method for measuring ground fault degree in an actuator sensor interface-sensor-actuator-network.
