HFL gets your generator running!

HFL was called to a non-operating generator at a recently converted office to residential property.

HFL contract manager Derek Smith took on the investigation and found the following problems with the installation:

  • The generator was suspected to have never operated due to the condition of the installation, even though there was commissioning paperwork for the installation.
  • No provision had been made for the air supply and discharge to run the machine;
  • The electrical cables from the change over panel were undersized relative to the output of the engine.

Following conversations with a generator specialist the below options were actioned to resolve the generator not running:

  • The generator was to be lifted and turned around 360 degrees so the intake and discharge points were facing an exterior wall;
  • The external wall of the building was to be specialist cut with diamond drilling experts to cut an opening in the exterior concrete wall;
  • Ventilation ducting was installed from the generator to the newly cut hole to exterior wall separating the discharge hot air and air intake;
  • To deal with the cable under sizing the generator’s output, switchgear was downrated to protect the actual required electrical load of the site.

Just another remedial project for HFL!
