Generator Maintenance

Generator Service and Maintenance

Diesel generator sets used for either prime or standby emergency power must be regularly serviced and maintained to ensure they provide power, when called to do so, throughout their service life.

Large and small companies who own generators, or those who rely on them extensively for prime power, have established service and maintenance contracts with P & I to service their equipment and minimise their risk.

Our generator service maintenance programs follow the recommended schedule by the manufacturer of the engine and alternator.

Our extensive knowledge of generators provides us with the expertise to predict when certain components require change – before a failure arises.  Replacement parts can be tested during a planned service visit and a reliable service and maintenance schedule is employed by P & I who have gained many years of experience in the power generation industry.  Adhering to this schedule will ensure maximum performance from your generator when and if it is called into operation.  P & I have well established service and maintenance plans for all different plant and machinery and we not only service plant and equipment supplied by us but also any brand and make of generator and switchgear you may have.

Generator Maintenance

The main objective of the P & I service and maintenance teams is to give satisfaction, security and peace of mind to our clients.

Some of the steps taken to ensure smooth generator operation, while carrying out scheduled service and maintenance include:

  • Timely removal of worn out parts or upgrading of components
  • Oil and fuel sampling
  • Checking fluid levels
  • Battery inspection and cleaning of connections
  • Load bank testing
  • Verifying control panel settings and indicators
  • Changing fuel, oil, water and air filters.
  • Fuel polishing
  • Fuel tank and pipework supply and installation

Small investments made in replacing components and maintaining generators, on a regular basis, can save expensive and unnecessary repairs and down time, or even replacement of the entire generator in the future.

When performing routine maintenance, each action taken is logged and the readings and various parameters are recorded along with the date of inspection and hour meter reading. These readings are compared with subsequent or previous data collected and any variation of readings could indicate a potential fault of the unit.

On site testing of Automatic Transfer Switches (ATS) and transfer Air Circuit Breakers (ACB) will ensure that your changeover is worked at regular intervals, checking the electrical and mechanical integrity of the transfer operation.  Other factors to be checked periodically are starting and timing relays, start signal continuity and utility phase sensing.

Preventative maintenance ensures uninterrupted power supply when you need it and as a contract customer, you are assured of a priority call out service and reduced hourly rates.

Once a business enters into a contract they can rest assured knowing P & I will keep track of when the next full or interim service is due and our records will enable us to plan any additional service visits and checks.  We can then program any additional work that could be carried out at the same as your full or interim service thus saving costs on a revisit.
