Improve hardware facilities and work algorithms of overhead contact line remote monitoring systems

An autonomous diagnostic measuring device, that allows to reduce expenses for the maintenance and the need for highly qualified personnel, is proposed in the article. The described algorithm of the work of the measuring system allows setting pre-failure conditions of an overhead contact line during exploitations of the software complex. The Installation scheme of the measuring complex on an overhead contact line equipment and the functional scheme of the software and hardware complex are described. The experimental dependence of the vibration frequency on the contact wire tension is defined for various overhead contact line spans. The limits of the variation of the vibration frequency for various combinations of overhead contact line parameters are defined
