Purpose

As a device to support the uninterrupted operation of electrical equipment of up to 0.69 kV of process facilities in case of main types of power failures, allowing for predicting and early detection of such failures.

Functions
  • Non-stop operation of electrical equipment of process facilities in case of main types of power failure
  • Prevention of synchronous motors from out-of-step falling, falling out of magnetic starters and contactors of low-voltage electrical loads
  • Synchronous switching of a faulty bus bar section to a standby input without overcurrents
  • Improvement of conditions for self-starting of electric motors after restoration of power supply to loads
  • Oscillography of transient processes of violation and recovery of power supply normal parameters of sections
