Maintenance and Replacement of Hitachi ABB Power Grids PQFS Active Harmonic Filters

June 2021

This notice provides information for businesses and individuals who have purchased, installed, or are responsible for the maintenance of Hitachi ABB Power Grids PQFS active harmonic filters.

The purpose of this notice is to inform you of changes to the expected lifespan and required replacement of output filter cards, located inside Hitachi ABB Power Grids PQFS active harmonic filters.

Hitachi ABB Power Grids has determined that the output filter cards should now be treated as a consumable component and be replaced every 5 years. This change is due to new data and analysis showing that the lifespan of capacitors mounted on output filter cards is shorter than previously thought and varies depending on use.

If your filter is more than 5 years old, the output filter card needs to be replaced. You may also be required to immediately disconnect your active filter from service.

It is important that you contact us as soon as possible to determine what action needs to be taken, as there is a risk that a potential thermal incident could occur, which may result in injury or damage.

If your filter is less than 5 years old, the new maintenance schedule requires the output filter card be replaced before it is 5 years old and then every 5 years.
