Power Factor Correction Maintenance

They contacted Power Efficient Solutions to assist them with improving their electrical efficiency and reducing energy spend.

After assessing the client’s data, we identified a relatively poor power factor of 0.85 (lag) or 85% efficient and followed up with a site survey.

During our site survey we identified an existing power factor correction unit, offering almost zero correction, due to capacitor deterioration.

We carried out a full maintenance visit on the PFC unit and made recommendations to return the unit to its fully rated output and recommission.

This work was carried out during normal working hours, with no disruption to the clients’ normal operations, and led directly to a power factor improvement from 0.85 (lag) to 1.00 (unity) and offered a return on investment of under 9-months, as detailed below.
