SYSTEM AND METHOD FOR MONITORING THE AMPACITY OF OVERHEAD POWER LINES

摘要

The invention relates to a system for monitoring the ampacity of overhead power lines, which includes monitoring modules (7) installed in respective sets of spans (14) and a remote unit (16) which receives and processes sets of measured data (13) received from the modules, each sensor arrangement being assigned to a set of spans (14), each one of which includes a traction sensor (6), an electric intensity meter (8), an ambient temperature sensor (9) and a solar radiation sensor (10); the data processing unit (16b) calculates the ampacity (AC) for each set of spans (14) according to each set of measured values (13) received, as well as a conductor traction-temperature reference (Ref-TT), the deformation by creeping (DF) and the maximum acceptable temperature (Tmax) of the conductor (2) for each set of spans (14) according to each set of measured values (13).
