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• 20-30 year old outdated solutions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
