Continuous voltage monitoring during work on overhead power lines

The article presents the results of the analysis of traumatism on the country's overhead power lines. Despite the reduction in the number of fatal electric injuries, the risk of such injuries remains at an unacceptably high level. High severity of consequences remains stable - about half of electric injuries end in the death of the employee. The most injury-prone areas are constantly overhead power lines with voltage of 6-35 kV. The severity of consequences of electric injuries is explained, in particular, by the unexpectedness of getting under voltage, the presence of which on live parts is not manifested externally. To control it, voltage indicators and signaling devices are used. Unfortunately, a significant part of them has significant drawbacks, and the operation of checking the absence of voltage is carried out once before starting work.
