Criterion of Safe Operation of Metal Structures of Supports
Abstract
The paper deals with the durability of metal structures of supports which is one of their important properties necessary for the successful and accident-free operation of electric transmission lines. The criterion of safe operation is determined in the paper using a method of measuring the ultrasonic rate of the real supports. As a result the obtained dependence allows the quantitative analysis of the support lifetime. Measurements are carried out in Elabuga (Tataria).
