Harmonic Filter

Harmonic compensators for electrical installations in office buildings IP-20

Solution 1 Filtering of harmonics 3^th, 9 ^th and 15 ^th

Compensator C10D + C20D

The C20D Compensator provides a very good cost-filtering relation. It reduces the triplen harmonics (3rd, 9th, 15th), and eliminates this way the main problems in the office installations, which are overloaded neutral conductors and a high neutral-earth voltage. It is recommended to install the C20D always with the Impedance Adapter C10D in order to obtain the most optimised filtering and functionality.

Filtering results:

Reduction of neutral current and neutral - earth voltage                    up to 75 %

Reduction of phase current                                                           up to 15 %

Reduction of voltage and current distortion                                      up to 45 %

Obtain P.F. factor                                                                        up to 0,80

Solution 2 Filtering of harmonics 3 ^th, 5 ^th, 7 ^th, 9 ^th, 15 ^th, 17 ^th and 19 ^th

Compensator C10D + C20D and C10D + C22D

The C22D Compensator offers an elevated filtering of harmonics 3th, 5th, 7th, 9th, 15th, 17th and 19th, this way solving all common harmonic problems in the electrical installation. The C22D is used in combination with the C20D+C10D, each supplying 50% of the total load to be filtered. It is recommended to install the C20D and C22D always with the Impedance Adapter C10D in order to obtain the most optimised filtering and functionality.

Filtering results:

Reduction of neutral current and neutral - earth voltage                    up to 80 %

Reduction of phase current                                                           up to 40 %

Reduction of voltage and current distortion                                      up to 75 %

Obtain P.F. factor                                                                        up to 0,95

Solution 3 Filtering of harmonics 3 ^th, 9 ^th and 15 ^th, with galvanic isolation

Compensator C25D

The C25D Compensator is totally eliminating the triplen harmonics (3rd, 9th, 15th), avoiding any type of

overload in the neutral as well as a high neutral-earth voltage produced by harmonics.

Thanks to its galvanic isolation, the C25D Compensator represents the ideal solution in case of a high level

of 3rd harmonic voltage. Additional advantages are: reduction of the electromagnetic disturbances coming

from the supply network, optional voltage adaptation and the possibility to use independent earths as the

neutral is isolated from the mains.

Filtering results:

Reduction of neutral current and neutral - earth voltage                    up to 90 %

Reduction of phase current                                                           up to 15 %

Reduction of current distortion                                                       up to 45 %

Reduction of voltage distortion                                                      up to 40 %

Obtain P.F. factor                                                                        up to 0,80
