The article deals with the digital substation equipment maintenance. Equipping the electrical substations secondary circuits with intelligent electronic devices (IEDs) is an important direction in the electric power industry digital transformation. The purpose of the work is to develop an algorithm for testing digital substation protection devices for the influence of network distortions in the process bus. The tasks are to identify the main distortion types, determine the maintenance content and test it. The need to expand the existing service is determined, the maintenance algorithm is developed and a pilot test of the network distortions effect on the IED protection functions is performed.
