How to Work automatic transfer switch(ATS) with dual power supply

1) what is the ATS ?
ATS is abbreviation of automatic transfer switch, it is use to change over power source of dual feedings i.e Primary source & secondary source.

2) incoming source of ATS.
ATS connected from two source
👍primary_source generally electricity supply from government/private organisation and  secondary_source will be generator and interrupted power supply(UPS) etc.

3) Function of ATS.

An automatic transfer switch (ATS) is a device that automatically transfers a power supply from its primary source to a backup source when it senses a failure or outage in the primary source. When a failure occurs in a primary power system, the ATS invokes a standby power source, such as an uninterruptable power supply. An ATS can also start up more long-term backup power systems, such as local diesel generators, to run electric equipment until utility power is restored.

Since the ATS is connected to both primary and backup power sources, it serves as an intermediary between equipment and the power supplies, acting as an electrical relay. An ATS can also act as a redundant, rack-mounted power supply for equipment that is connected to a power source with only one cord.

In the data center, it is vitally important to have uninterrupted power. To achieve this goal, the systems in the power path must be properly maintained and tested. To ensure reliability in the event of a power outage, data center administrators need to routinely monitor the ATS.
 ATS units can channel considerable amounts of energy, which can put heavy stress on the electrical contacts involved, so regular maintenance is critical.

4)How to remotely control an automatic transfer switch.

As you see on the automatic transfer switch Video, you can connect a switch for a remote control from BMS (building management system).
In side ACB under voltage coil also function to open Load supply if incoming voltage down to under 200 volt for domestic use and 370 volt for 3 phase power system.
