PFC Power Factor Correction


At BMC we manufacture fully automatic power factor correction banks designed specifically to customer requirements from 25Kvar up to 900Kvar in the standard type.


We have three main offerings:

Standard Type for (no polluted network Gh/Sn £ 15%)

Overrated Type for (polluted network 15%

Detuned Type for (polluted network 25%

These are manufactured using the Schneider Electric Varplus M capacitors from 230 to 690 volts.

These capacitors use a self-healing metallised polypropylene film requiring no gas or liquid impregnation. With the built in HQ protection system to protect against both high and low current faults, and very high quality plastics with outstanding mechanical properties and maximum self-extinguishing ratings (UL945 VA certification).

The controllers we use are the Varlogic R6 and R12 which are insensitive to CT polarity and phase rotation polarity they also have an automatic C/K ration search facility all of the above simplify the commissioning process.

We use the LC1-D-K contactors which are specifically designed for capacitor switching. The contactors are equipped with a set of contacts and current limiting resistors. This technology is unique and patented.

Our service includes site survey to confirm clients requirements, custom manufacture to meet with each customers specific site conditions, installation and commissioning followed by our comprehensive service and maintenance offering which includes thermal imaging. Details of our thermal imaging service and the cameras we use are available in the maintenance section of this site.
