If the primary source fails or the voltage drops below a certain threshold, the switching circuitry instantly transfers power to the secondary source, providing uninterrupted power. By having a dual power supply, systems can experience increased reliability and redundancy.
In other words, a distribution room is equipped with two independent power sources (from two different supply systems) to ensure uninterrupted power supply, referred to as a dual power supply. During normal operation, one power source supplies power while the other acts as a backup.
On the other hand, a dual power transfer switch is a device used in dual power systems to achieve automatic power switching. When the primary power source fails or there is a power outage, the dual power transfer switch can automatically detect and switch to the standby power source, ensuring uninterrupted operation of equipment or systems.
These two power lines usually come from substations in different directions or from different busbars in the same substation with two or more incoming lines. One of the power sources is referred to as the primary power source, while the other serves as the standby power source.
