摘要

#CMT# #/CMT# The device has a measurement resistor (R9) for measuring a current passing through a harness to be monitored. An amplifier circuit (I) amplifies variations of current exceeding a preset threshold. A conditioning circuit (II) transforms a profile of the measured current into a voltage representative of energy corresponding to current. A detector circuit (III) detects the energy level, resulting from anomaly, causing damage to the harness, and a signal generator responds to the observed anomaly. #CMT#USE : #/CMT# Used for detecting anomaly of an electrical harness in a motor vehicle (claimed) and electrical installation. #CMT#ADVANTAGE : #/CMT# The device is completely autonomous and independent to parts of the motor vehicle, and ensures the efficient protection of supply lines of the vehicle on all the phases of the vehicle while avoiding the need of fuses, whose efficiency is not guaranteed. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows an electrical diagram of an anomaly detecting device.
