harmonics filter
It is possible to install a harmonics filter between the AC input power source and
Comet in order to reduce the level of current harmonics absorbed by the source.
This option is available only for Comet series 31 and series 33 units with a rated
output at least equal to 15kVA.
The cables requiring connection are indicated as bold lines.
For information on cable cross-sections, see the "appendices": "selection of cable
cross-sections" (the connection cables between Comet and the option are
supplied).
