PFC Unit upgrade at the supermarket

An end-of-life replacement was required for an old Power Factor Correction unit at a supermarket in central London.

A new wall-mountable FS100 PFC unit was to be installed using the existing power and C.T connections. The unit would incorporate 4  25kVAr capacitor banks, 480V rated with IMO MC32 soft switching contactors, sub fusing and additional forced air ventilation.

 

The unit would be controlled via a local Lovato DCRL 5 digital control relay and also include an integrated 200A load break switch for local isolation.

 

When operating the site power factor would be improved from 0.81 inductive to a unity power factor helping to save money on the monthly electricity bills by removing any reactive charges.

 

This unit was installed in 1 day by 1 engineer during normal working hours without any disruption to the site’s supply.
