The composition of the UEP-U-M is determined by the project and may include UVZF, PVM-E, PRM-E, BK, SHAKB, UAO, RSHT and UBP.
Connection of cables of two external sources of three-phase alternating current (main feeder, backup feeder) and DGA feeder.
Continuity of power supply to the loads connected to the uninterruptible power system during the set time, when switching external power supplies or when they are turned off.
Continuous monitoring of normalized parameters of external power sources: overvoltage, voltage drop in any of the phases, phase sequence, phase failure, AC frequency.
Control of operation of surge protection devices, control of operation of circuit breakers, control of operability of direct current sources, indication of operability of UBP remotely by means of a supervisory control system.
Work in modes with the predominance of one of the feeders or equivalent feeders.
Transmission of information about the emergency state of UEP-U via cellular communication systems by means of an SMS message sent to the mobile phone of an SCB electrician, an SCB distance dispatcher.
