What is the difference between Open and Close transition for Automatic Throwover Applications?
Issue:
Automatic Throwover.
Product Line:
Switchgears and Switchboards.
Environment:
Switchgears and Switchboards.
Cause:
Define Open and Close Transitions.
Resolution:
The Automatic Throwover System (ATS) operates when the primary source is shut down, transferring the load to the secondary source. In other words, the ATS disconnects the load from Source 1 and connects it to Source 2, which can be a secondary utility or an emergency generator, ensuring a steady power supply.
In a closed transition, there is a brief period when both sources are connected to the load simultaneously, operating in a parallel system. In contrast, during an open transition, both sources cannot be connected at the same time.
Switchgears and switchboards usually have ATS functionality, which can be controlled by a Programmable Logic Controller (PLC) or Protection Relays.
