PFC Tray Assembly Replacement at Meat Factory.

This 350kVAr Power Factor Correction unit installed in 1998 was found to have multiple capacitor failures following a long period of not being annually maintained.

It was decided that an end-of-life replacement for all the tray assemblies would be the best option. As such we swapped out the old-style SBA trays with its cascaded contactor steps with a more modern SBA tray with two 50kVAr soft switching contactors on each and 480V-rated capacitors.

We also included a smaller tray with two stages of 25kVAr for finer correction at different loads.

As well as this we also installed forced air ventilation into the front of the panel to help regulate the internal temperature of the unit.
