In modern life, the development of large cities is associated with the speed characteristics of the movements of people in them. There is a relationship between the territorial expansion of the city and the development of transport communications. One of the important tasks of the municipal councils in the settlements is to provide fast, reliable and cultural services

to the population within the city and the adjacent suburban areas, through scientifically based

approaches, methods and means. Well-organized urban passenger transport plays an important role in the proper functioning of a territorial unit.

The material analyzes the operational readiness of the existing power supply lines and equipment in the traction rectification stations (TRS) and the existing air contact network (ACN) for electricity supply of trolleybus transport in the city of Plovdiv. The ments for maintenance and operation of TRS and ACN in terms of their parameters and available documentation are presented. The energy efficiency of the power supply network in case of possible purchase of new electric vehicles was also monitored. The reliability of the equipment and devices for switching and protection is also considered. The aging and durability of the insulation materials in the existing power supply system of non-autonomous rolling stock have been monitored. The importance of the human factor in the operation and maintenance of electrical equipment is indicated. In conclusion, general conclusions are
