Servicing Report - ABB PQFM Instruction Manual

Stocked or non-operational filters should be reformed once a year. The method
described here assumes that the filter is stocked in a clean and dry environment.
To reform the capacitors,
- Switch on the power supply to the filter without starting the filter for about 2
hours. Verify with the PQF-Manager the DC capacitor voltage and ensure that it
is charges to a couple of hundred volts.
- Then, with all harmonics and reactive power and balancing functionality
deselected, start the active filter and leave it running for one hour.
- The filter is now ready for normal operation
If the filter has been left more than 2 years without operation, please contact your ABB
service provider.
