Claim Text:
1. A method of monitoring a power transmission line, said method comprising: measuring, by a measuring device, at a measuring point along the power transmission line, a characteristic associated with the power transmission line and obtaining a measured data signal representative of the characteristic associated with the power transmission line; periodically transmitting by a measured data acquisition unit a synchronization signal including a plurality of synchronization pulses over the power transmission line; receiving the synchronization pulses transmitted by the measured data acquisition unit at the measuring device; repeatedly transmitting the measured data signal from the measuring device over the power transmission line, wherein each of the repeatedly transmitted measured data signals is the same when transmitted by the measuring device and wherein each transmitted measured data signal is delayed in transmission from a corresponding one of the plurality of synchronization pulses; receiving at the measured data acquisition unit the repeatedly transmitted measured data signals; and averaging the received repeatedly transmitted measured data signal to obtain an averaged measured data signal indicative of a characteristic of the power transmission line at the measuring point.
