S staranjem obstoječih daljnovodov so pomanjkljivosti zaradi različnih mehanskih okvar na opremi in nepredvidljivih vremenskih razmer na teh daljnovodih pogostejše, kar vpliva na zanesljivost obratovanja in višje stroške vzdrževanja. Predstavljen je merilni poligon Kleče–Logatec, ki ga sestavljajo sistem Dynastrain za kontinuirano spremljanje nateznih napetostih v nogah daljnovodnega stebra in naprave OTLM za spremljanje ključnih parametrov vodov. Rezultati poligona so pokazali, da spremljanje spremembe deformacij v podpornih stebrih omogoča zaznavanje obremenitev na stebru, ki so lahko tudi posledica sprememb sil v vodih. In the master's thesis, we present new measurement methods for monitoring key parameters of power transmission lines, which provide support for more efficient operation. As existing power transmission lines age, errors due to various equipment failures and unpredictable weather conditions on these lines become more frequent, affecting the reliability of operation and increasing maintenance costs. The Kleče–Logatec measurement polygon is presented, which consists of the Dynastrain system for continuous monitoring of tensile stresses in the legs of the tower and the OTLM device for monitoring key conductor parameters. The results of the polygon have shown that monitoring changes in deformations in support columns allows for the detection of loads on the column, which may also be the result of changes in forces on the conductor. visokonapetostni stebri natezne sile nadzemni vodniki sprotni nadzor vodnikov (DLR) poves vodnika high-voltage towers tensile forces overhead conductors dynamic line rating (DLR) conductor sag true true false [M.
