According to the Decree of the President of the Russian Federation dated May 7, 2018 No. 204 "On national goals and strategic objectives of the development of the Russian Federation for the period up to 2024", it is planned to increase the capacity of the Baikal-Amur and Trans-Siberian railway by one and a half times. Today it is important to increase the capacity of railways. One of the ways to achieve this goal is to eliminate downtime of alternating current electric locomotives on the stretch following insulation breakdown and failure of power groups. This is possible by developing a method for monitoring the insulation condition of the power groups of an alternating current electric locomotive in operation. This approach makes it possible to assess the serviceability of the insulation of the electric locomotive power groups and carry out repairs in a timely manner based on its current condition. The article discusses the methods of monitoring the insulation condition of alternating current electric locomotive power groups in depot conditions, as well as their advantages and disadvantages, according to the results of comparison of which the choice of a method for monitoring the insulation condition is significantly superior to others. The chosen method is recommended for monitoring the insulation condition of the power groups of an alternating current electric locomotive in operation.
