Abstract
Способ определения места повреждения линий электропередач и связи, заключающийся в посылке в линию зондирующих сигналов напряжения с времячастотной модуляцией от генератора при согласовании выходного сопротивления последнего с волновым сопротивлением линии в соответствии с заданным диапазоном волновых сопротивлений и требуемой точностью согласования, приеме отраженных сигналов, которые подвергают демодуляции, фильтрации и спектральному анализу, отличающийся тем, что в линию посылают непрерывные сигналы с времячастотной модуляцией, а место повреждения линии определяют по разности частот зондирующего и отраженного сигналов. The method for determining the location of damage to power lines and communications, which consists in sending voltage-sensing voltage-frequency modulated signals from the generator to the line while matching the output impedance of the latter with the line impedance in accordance with a given range of wave impedances and the required matching accuracy, receiving reflected signals that are subjected to demodulation filtering and spectral analysis, characterized in that the line sends continuous signals with time-frequency modulation minutes, and the injury line determined from the difference frequencies and the reflected probe signal.
