The paper presents the structure of the system under development for uninterruptible power supply indexes monitoring. Functional description and main structural elements of this system are given. It is shown that components of automatic system for commercial measurement of power consumption, structural units of implemented smart voltage control system for 6–20/0.4 kV networks and installed multifunction metering devices can be used as information sources for the monitoring system operation. The main categories of system users and available information for each category are given. The main stages of monitoring system implementation are proposed.

Single-core a number of features, and one of them is the presence of induced currents in double end grounded copper screens which resulting in addition active power losses. For power reduction there are some technical solutions like one end screens grounding or screens transposition. In particular, one of the pressing questions is, are there any restrictions on the length of the connecting wires, which connect transposition joints with link boxes.

Outdoor switchgears without portals with one and a half breaker bus systems and 4/3 breakers bus systems are designed for power systems of Russia and other countries that operate 500 kV backbone power lines and generate electric power by means of thermal, nuclear and hydro power plants. There is no bus arrangement around circuit breakers in all switchgears. It creates favorable conditions for quick and safe circuit breaker cells replacement. Constructional units with double-deck rigid tubular buses give a possibility to avoid construction of bulky resource-demanding portals and busbar system portals in outdoor switchgear. Application of those constructional units provides a significant reduction of land dedicated to outdoor switchgears, reduction in consumption of construction materials and an increase instructural reliability. Besides, the value of outdoor switchgears building and costs for repair and maintenance of equipment are declined. Developed constructional units can also be used for other bus connection schemes such as mesh-connected scheme, “transformer-buses” scheme and others. Technical decisions can be used for advanced development of 300 and 400 kV outdoor switchgears.
