After the new Morrinsville manufacturing facility was built and commissioned, power analysis was undertaken of the site energy usage. As a result it was identified that a power factor correction unit would need to be installed.

Hennessy Group designed and built in house a 350KVAr power factor unit with chokes to eliminate harmonic content.

Due to the large currents involved a forced air ventilation shroud was installed that removed the hot air from the chokes/capacitor cabinet and vented this air safely outside the electrical switchroom.

Work carried out included:

  • Detailed power analysis of site energy usage.
  • Pre-planning for production shutdown and restart.
  • Design cabinet layout specify component sizing.
  • Assemble components and mount to cabinet gear plates.
  • Install and terminate all wiring looms between cabinets.
  • Complete system tests and monitor resultant electrical energy values.
