Generators are essential equipment that provides backup power to commercial buildings, industrial facilities and businesses that rely on a continuous electricity supply. However, like any other mechanical equipment, generators also develop problems over time. For instance, you might notice overheating and fuel system failures suddenly when you need it most.
These issues affect performance and create unexpected downtime on the factory premises. Professional generator service in London provides industries and commercial sectors with repair and servicing to keep generator systems running reliably.
What are the common generator faults?
Generator fails to start
If your generator refuses to start, it is one of the most common problems businesses face, especially when it hinders production. The cause is often a dead battery or a damaged starter motor; loose electrical connections can also cause the problem.
How professionals fix it
Experienced engineers inspect the battery condition, check the electrical connections, and repair the charging system to ensure the generator starts instantly. However, if these quick remedies don’t work, they will investigate the defective component and replace it. Regular battery testing and scheduled generator servicing reduce the risk of starting failures or power outages.
Generator overheating
Excessive heat can affect the generator’s performance and damage critical components. Common causes include blocked radiators, restricted airflow, damaged cooling fans, excessive operating loads, and low coolant levels.
How professionals fix it
A qualified engineer will check coolant levels and identify what is blocking the airflow system. They also check the SSP generator and its operating capacity. Depending on the findings, they will repair the radiator, clear the airways, and fix the underlying load issues.
Fuel system problem
Diesel generators are particularly vulnerable to issues like fuel contamination in the fuel lines, damaged injectors, or clogged filters, which can prevent the generator from starting.
How professionals fix it
Professionals inspect the fuel tank condition, the filter pipe, and the injection system, and look for causes that restrict fuel flow. They replace clogged filters, check for contaminated fuel, and repair damaged components when necessary. Repeated fuel quality checks help prevent this problem from recurring.
Low or unstable power output
A generator that produces insufficient or fluctuating voltage generally struggles to support connected equipment. Possible causes include alternator faults, damaged voltage regulators, poor engine performance, and loose connections.
How professionals fix it
Engineers test the generator’s voltage capacity and check its frequency and output under suitable operating conditions. They also inspect the alternator and automatic voltage regulator before replacing damaged parts to restore the generator’s performance.
