An Automatic Transfer Switch (ATS) helps transfer a facility’s electrical supply between mains power and a standby generator. When the ATS develops a fault, the generator may fail to start automatically, power may not transfer correctly, or the system may experience unwanted interruptions.
Professional generator ATS repair in Lagos can help homes, offices, hotels, hospitals, estates, factories and other facilities restore reliable automatic changeover.
Common Generator ATS Problems
An ATS fault can affect the relationship between the generator and the building’s electrical supply. Common symptoms include:
- Generator fails to start when mains power goes off
- Mains power returns but the system does not change back
- Delayed or failed power transfer
- ATS remains stuck on one power source
- Frequent transfer or switching problems
- Fault alarms or indicator warnings
- Contactor or relay problems
- Wiring and connection faults
- Generator and ATS failing to communicate correctly
The actual cause needs to be diagnosed before components are repaired or replaced.
Generator ATS Diagnosis and Repair
ATS problems can originate from the switch itself, control wiring, relays, contactors, sensors or the generator control system.
A technical inspection may include checking the ATS controller, electrical connections, contactors, transfer mechanism, control signals and related generator components.
Where a faulty component is identified, the appropriate repair or replacement can be arranged based on the equipment and installation.
Automatic Changeover Problems
One of the most noticeable ATS faults occurs when the generator does not respond automatically after a mains power failure.
If the generator starts but the building does not receive generator power, the problem may involve the transfer mechanism or associated control system. Conversely, if mains power returns but the system does not transfer back correctly, the ATS may require technical inspection.
ATS Repair for Commercial Facilities
Reliable automatic transfer is particularly important for facilities that cannot afford prolonged power interruptions.
ATS repair and technical support may be useful for:
- Offices
- Hotels
- Hospitals
- Factories
- Estates
- Warehouses
- Construction sites
- Commercial buildings
The ATS should be assessed together with the generator and electrical installation where necessary, rather than treating the transfer switch as an isolated component.
Generator ATS Replacement or Upgrade
Some ATS faults may be caused by an outdated or heavily worn system. In such cases, repair may not be the most practical option.
A technical assessment can determine whether the ATS should be repaired, replaced or upgraded. Compatibility with the generator, electrical capacity and existing changeover arrangement should be considered before selecting new equipment.
