The "Static Transfer Switch (STS)" is the key component that enables seamless switching between the utility and backup power sources.
The "Critical Loads" are the devices or systems that require uninterrupted power.
Utility Power Source: This is the primary source of power from the electric grid.
Backup Power Source: This could be a generator, an uninterruptible power supply (UPS), or another alternative power source.
The control system monitors the quality of the incoming power from both sources and makes decisions about when to switch between them.
It may include sensors for voltage, frequency, and phase monitoring to determine the quality of the power sources.
Under normal conditions, the system is powered by the utility grid, and the STS routes power from the utility source to the critical loads.
The control system continuously monitors the utility power quality.
This transfer ensures that the critical loads continue to receive power without any disruption.
