Capacitors
Reforming the capacitors
The converter modules employ several electrolytic capacitors. Their lifespan depends on
the operating time of the converter, loading and the ambient temperature. Capacitor life
can be prolonged by lowering the ambient temperature.
It is not possible to predict capacitor failure. Capacitor failure is usually followed by
damage to the unit and an input cable fuse failure, or a fault trip. Contact ABB if capacitor
failure is suspected.
Reform (re-age) spare part capacitors once a year according to
Converter modules with
electrolytic DC capacitors in the DC link Capacitor reforming instructions
