Electrical power supply system and diagnostic method

摘要

Electrical power supply system for actuators (2.1-2.n) in drive units, especially electromagnetically activated actuators of a gear unit with a circuit arrangement. The power resistance of the individual supply lines and the earth return line are determined over an initial time and used to form reference values. Subsequent measured values are compared with these stored reference values. An Independent claim is made for a diagnosis method for electrical power supply systems.
