The article provides brief information about new fast-operating automatic standby activation device is located in indoor switchgear with two and more bus bars. Fast-operating automatic standby activation device allows connecting between reserve switching supply and alarm bus bar with minimum difference between voltage vectors. It also reduces current blow in a grid and dynamic influence in pumps and pipelines.
Thyristor device's application allows improving of automatic standby activation device's reliability performance. Also it will reduce current blow in a grid and dynamic effect in mechanisms and pipelines.
