The article presents information that facilitates monitoring and diagnosing wear of contact wires in traction electrified railways. Classifications of the causes of damage and the corresponding types of wear of the contact wire are given. A method is proposed for calculating wire wear by the measured width of the worn surface or height from the base line, which are entered into a mobile phone, which contains a program for calculating wear as a percentage, during maintenance of the contact system. An algorithm for calculating wear is given [2].
