An Automatic Transfer Switch (ATS) controls the changeover between public power and a standby generator. When it develops a fault, a building may experience problems such as failed automatic changeover, delayed transfer or the generator failing to respond when mains power goes off.
Automatic transfer switch repair in Lagos is therefore important for homes, offices, hotels, hospitals, factories, estates and other facilities that depend on automatic backup power.
Common ATS Problems
An ATS can develop different faults depending on its age, installation and operating conditions. Common signs include:
- Generator fails to start automatically
- Power does not transfer from mains to generator
- Generator starts but the building remains without power
- System fails to return to mains when power is restored
- Delayed changeover
- Frequent switching between power sources
- Fault alarms or warning indicators
- Damaged contactors, relays or control components
- Loose or damaged wiring
The visible symptom does not always identify the actual cause, so the system should be properly diagnosed before replacing components.
What ATS Repair Involves
A technician may inspect the ATS controller, contactors, relays, wiring, control signals and transfer mechanism. The generator and related electrical connections may also need to be checked because the fault can originate outside the ATS itself.
Where a damaged component is identified, it may be repaired or replaced depending on the condition and design of the system.
Generator Starts but Does Not Transfer Power
One common problem is when the generator starts after mains power fails but the building does not receive generator power.
This can point to a problem with the transfer mechanism, control circuit, contactor or related wiring. The ATS should be tested by a qualified technician rather than repeatedly forcing the changeover manually.
When an ATS Needs Replacement
Not every faulty ATS needs to be replaced. However, an old, badly damaged or incompatible unit may be more suitable for replacement than repeated repairs.
The replacement should match the generator capacity, electrical load and existing installation. Proper sizing is important because ATS systems are available for different electrical capacities and applications. (Fembosco)
ATS Repair for Businesses in Lagos
Power transfer problems can be particularly disruptive for businesses that depend on generators for daily operations.
Offices, hotels, factories, warehouses, hospitals and commercial buildings may require quick technical assessment when automatic changeover stops working. Some Lagos electrical engineering companies provide ATS panel repair, maintenance, installation and related control-panel services. (Rihanco Nigeria Ltd)
How Travo.ng Can Support Generator ATS Repair
Travo.ng can help coordinate eligible generator ATS repair, diagnostics, replacement and related technical support in Lagos.
When requesting assistance, provide the generator location, generator make and model, ATS details if available, description of the fault and whether the generator starts automatically. These details can help the appropriate technical team understand the situation before attending to the system.
What to Check Before Calling for Repair
Have the following information ready:
- Generator make and model
- ATS brand and model
- Generator capacity
- Description of the fault
- Whether the generator starts automatically
- Whether power transfers manually
- Location of the generator and ATS
- Any error message or indicator showing on the panel
- Recent electrical or generator work carried out
Avoid opening or attempting to repair a live ATS panel yourself. Electrical transfer equipment can involve dangerous voltages, so diagnosis and repairs should be handled by a qualified electrical or generator technician.
