Preserving Your Generator's Performance

Preserving Your Generator's Performance

A generator can be a powerful engine, creating the necessary energy to power appliances in our daily lives. However, a generator's performance is only as good as how well it is maintained and serviced. Without proper checks and maintenance, a generator's mechanical components would start to wear out with time and with use. Generators require regular maintenance to retain optimal durability and reliability. (Regardless of whther it is used for active power generation or as a standby generator)

Here at Megatech, we offer essential maintenance servicing of your generators to preserve its durability. The most important and technical aspect of maintenance is the execution of a generator load bank test. This generally involves running the engine at 100% capacity into an external load outside the grid so as to not cause a power surge in the grid. Contact us to get a quote now!

Frequency of servicing depends on how often the generators are used. However, generators should be tested and runned for an hour at 100% capacity at least once annually. Lubricating oil within the machine requires regular replacement as they break down over time. They will need to be replaced after 60 hours of engine use. Always ensure you have a maintenance log, keeping track of fluid levels, maintenance and inspection history, and engine testing results. Scroll down to find out more about inspections.

How to Inspect Your Generator?

  1. External components: Check for any obstruction to ventilation, leaks of any fluids, and corrosion of any components.
  2. Coolant levels: If the levels are below the recommended level, top up the coolant fluid mix approved by the manufacturer. Monitor the discharge temperature when the engine is running to ensure the coolant system is functional.
  3. Fuel delivery system: check that the fuel pressure is at the right level when engine is running. Clean fuel filters. Ensure all connection fittings are airtight. Because fuel degrade with time, checks should be carried out monthly via sampling from the supply lines and bottom of the fuel tank. There should be no discernible colour distinction from fresh fuel off the petrol station.
  4. Electrical system: Wires must be clean and free of damage or corrosion, batteries should be holding maximum power capacity and be fully functional.
  5. Test-Run: start the generator and leave it running until the temperature remains constant for at least 10 minutes. Look out for any unusual sounds, movement, smoke, leaks and fuel/oil consumption. To ensure the power generated does not interfere with the the main grid, a generator load bank test should be carried out by qualified technicians.(where power is directed to an external load outside the building’s circuit) Damaged or worn-out parts must be replaced immediately.

Note: The following steps serves as a rough not definitive guide on how an inspection should be done. Always consult a qualified engineer on the technical procedures of maintenance inspection. Alternatively you may contact us for more information.
