Electrical system for e.g. truck, has second current measuring unit that carries out current measurement in specific component path at which electrical component of specific-type is arranged, during operation of respective component

摘要

The electrical system (1) has an arc monitoring unit with a current measuring unit (I1) that carries out current measurement in a component path (6c) at which an electrical component (R1) is arranged, if the respective electrical component (R1) is switched OFF. A current measuring unit (I2) carries out current measurement in a component path (6d) at which an electrical component (R2) is arranged, during operation of respective electrical component (R2). The arc monitoring unit detects an arc based on the current measurement of current measuring units. An independent claim is included for a method for detecting arc in motor vehicle electrical system.
