Fast Automatic Bus Transfer System (FABT)


The improvement of electric power supply reliability and electric power quality



Fast operation by switching to by pass power source in order to keep all power consumers non-interrupting powered.

Field of use

0,4-6-10-35 кV Switchgear with 2 independent power sources, having motor or different sensitive to voltage sags load.

Negative facts

  •  20-30 year old outdated solutions;
  •   ordinary ABT use based on minimal voltage relay;
  •   ageing and outdating of technical solutions of high voltage equipment and relay protection systems in factories switchgears;
  •   not enough financing of modernization programs;
  •   stuff skills decreasing level of utilities and maintenance;
  •   changing relay protection settings due to increasing load of the transformers.
