FIELD: electricity.SUBSTANCE: in the method for detection of a power transmission line support a radiolocating signal is emitted with an antenna, a reflected signal is received, the amplitude of the received signal is compared with the threshold value, at the same time scanning is carried out with a directivity pattern in a sector of power transmission line location, the distance D1 is measured by the first received reflected signal, which has exceeded the threshold value, the distance D2 is measured by the second received reflected signal, which has exceeded the threshold value, the absolute value of difference is found between measured distances ?D=|D1-D2|, the decision on availability of a power transmission line support is made by position of the value ?D within 0.1K??D?K, where K - value of span between supports of a power transmission line.EFFECT: provision of the possibility to detect a support of a power transmission line when there is no current in its wires.1 dwg |
