DETECTION SYSTEM FOR DETECTING BY CAPACTIVIE CURRENT MEASUREMENT THE PROXIMITY OF AN OBJECT TO ELECTRICAL POWER LINES

摘要

A system and method for detecting the proximity of an object to an electrical power line. The system comprises an antenna (3) for receiving, by capacitive effect, a current of which the intensity if a function of the distance separating the antenna from the electrical power line. The other factors that influence the current are fixed, constant or are considered negligible. A measuring and conditioning circuit converts the current at the output of the antenna into a coded signal and transmits this coded signal to a control unit (6). The control unit (6) compares the coded signal to predetermined values stored therein. Alarms are generated by the control unit when the current from the antenna exceeds the predetermined values.
