A loss of power can result in operational delays, equipment damage, and economic losses in seconds and affect homes and businesses, hospitals, industrial facilities, etc. For businesses in the UAE, where power outages can have serious consequences for critical operations, a reliable backup power system is a must-have rather than a luxury. The automatic transfer switch (ATS) panel is another critical component that lets the generator automatically switch on when the power goes out.
Installing an automatic transfer switch in UAE guarantees quick, safe, and hassle-free switching between electric and fuel power, as well as a seamless experience. In any type of residential, commercial or industrial use, an ATS panel will improve safety, reduce downtime and ensure critical systems are operating until the primary source of power is back online.
What is an ATS Panel?
An ATS (automatic transfer switch) panel is a type of electrical control panel that automatically switches power from one source to another, usually the utility company and a generator.
Normally, electrical equipment is supplied with electricity from the power utility. In the event of power failure or excessive voltage drop, the ATS automatically alerts the generator to turn on. After the generator has been operating at stable conditions, the ATS then switches the electrical load from the utility to the generator.
Once utility power is restored, the ATS senses the stability of the power and returns the load to utility power. The generator then automatically turns off following a programmable cooling time.
Why Install an ATS Panel?
Many businesses believe that a generator will solve all the power outage issues. But it takes several minutes to start up a generator and to turn the electricity over, and it may require trained personnel.
An ATS panel eliminates these delays by automating the entire transfer process.
Some major reasons to install an ATS panel include:
- Immediate response during power failures
- Continuous power supply for critical operations
- Improved electrical safety
- Reduced downtime
- Automatic generator control
- Protection for sensitive electrical equipment
- Greater operational efficiency
For industries where uninterrupted power is essential, an ATS panel is a critical component of the backup power system.
How Does an ATS Panel Work?
An ATS panel continuously monitors the incoming utility power.
The operating sequence typically follows these steps:
1. Normal Utility Operation
The ATS maintains the electrical load connected to the main power grid under normal stable power supply conditions and monitors the voltage and frequency continuously.
2. Detecting a Power Failure
If the utility power fails or falls outside acceptable limits, the ATS immediately detects the problem.
3. Generator Start Signal
The ATS automatically sends a start command to the standby generator.
4. Generator Stabilization
Once the generator reaches the required voltage and frequency, the ATS confirms that it is ready to carry the load.
5. Load Transfer
The ATS disconnects the utility supply and safely transfers the electrical load to the generator.
6. Utility Restoration
When utility power returns and remains stable for the preset delay period, the ATS switches the load back to the utility supply.
7. Generator Shutdown
The generator continues running briefly for cooling before shutting down automatically.
This fully automated sequence ensures uninterrupted power with minimal human involvement.
Types of ATS Panels
ATS panels vary depending on the application. The selection of the appropriate type depends on the requirement of power, load sensitivity and operational priorities.
Open Transition ATS
Open Transition ATS is the most commonly used type.
It temporarily disconnects the load and switches the power between the utility and generator. This short break is usually only for a fraction of a second.
Suitable for:
- Commercial buildings
- Warehouses
- Offices
- Residential properties
Advantages include:
- Cost-effective
- Reliable
- Simple maintenance
- Widely used across industries
Closed Transition ATS
Closed Transition ATS switches both power sources on simultaneously for a short time, and then switches to the new power source. This approach yields practically one continuous power transfer.
Ideal applications include:
- Hospitals
- Data centres
- Airports
- Financial institutions
Benefits include:
- Zero noticeable interruption
- Better protection for sensitive equipment
- Smooth power transfer
Delayed Transition ATS
This type adds a programmed delay between the disconnecting of one power source and connecting another power source.
It is frequently implemented when motors or large equipment are to be stopped before reconnecting the power again.
Applications include:
- Manufacturing plants
- Industrial machinery
- Heavy equipment facilities
Bypass Isolation ATS
Bypass Isolation ATS allows maintenance without interrupting the power supply.
It enables technicians to service or replace ATS components while maintaining continuous electrical service.
Commonly used in:
- Hospitals
- Data centres
- Critical infrastructure
- Telecommunications facilities
Benefits of Installing ATS Panels
Installing an ATS panel offers significant operational and financial advantages.
Automatic Power Transfer
No need to manually switch during outages. Power is restored as soon as possible, without the intervention of operators.
Reduced Downtime
Business continuity is enhanced due to the near instant start-up after a power outage.
Enhanced Safety
Manual switching may present an electrical risk to the operator. ATS panels automate the process and switch in the proper sequences.
Generator Protection
ATS panels allow generators to only run when required and safely turn off once the power is restored from the utility.
Protection for Electrical Equipment
By transferring the power at the right moment, you won’t have to worry about voltage fluctuations or electrical surges affecting the equipment you power.
