PFC Upgrade at High Street Supermarket

This Power Factor Correction unit was found to be unsuitable for site during an annual maintenance inspection along with multiple failures. It was also noted that the capacitor stages for too coarse for the load and the site would benefit from a mixture of smaller and larger stages to allow the PFC to fine-tune its correction.

As such a new 5 stage 100kVAr Power Factor Correction unit was quoted to be installed with a mix of 13.5kVAr and 25kVAr capacitor banks all controlled via a Lovato DCRL5 digital control relay.

Utilizing the existing power and C.T cables kept the cost down for the customer and meant our engineer could carry out the work during normal working hours without any disruption to site supply.
