PFC Replacement at Highstreet Supermarket

 

This old 100kVAr Power Factor Correction unit had reached the end of its life expectancy and multiple internal components had started to fail. It also had very little to no annual servicing carried out on it and due to its location inside an external GRP container, it had also started to rust.

Following an on-site load survey carried out during the maintenance visit, it was confirmed that the 100kVAr was sufficient to reach a healthy power factor of 0.99 inductive and the site background harmonics were below 2%VTHd.

The unit was replaced with one of our standard FS100 fully automatic PFC units including all new 480V rated capacitors, soft switching contactors and a fully digital Lovato DCRL 5 control relay.

 

As the unit was being fed from its own dedicated 250A MCCB all the works could be carried out during normal working hours with no disruption to the site.
