摘要：

Magnetic nondestructive testing (NDT) for monitoring the equipment of overhead power lines (OHL) such as conductors, ground wires, and guy wires is discussed. Magnetic NDT allows effective testing of steel ground wires, guy wires, and steel cores of bimetallic conductors. The results of monitoring the conductors and ground wires of 35 – 220-kV OHLs in Rosseti networks are illustrated. The residual load-carrying capacity (strength) of the tested conductors and wires is estimated based on test data. It is concluded that magnetic detectors are effective in testing ground wires, guy wires, and steel cores of bimetallic conductors. © 2020, Springer Science+Business Media, LLC, part of Springer Nature.
