8.4.1 Power Rating
Grid conditions
Supply voltage
Mains voltage low/mains drop-out:
During low mains voltage or a mains drop-out, the filter continues until the intermediate circuit voltage drops below the
minimum stop level, which corresponds to 15% below the filter lowest rated supply voltage. Full compensation cannot be
8 8
expected at mains voltage lower than 10% below the filter lowest rated supply voltage. If mains voltage exceed the filter highest
rated voltage, the filter continues to work but harmonic mitigation performance is reduced. The filter does not cut out until main
voltages exceed 580 V.
