Power filters of higher harmonics

Power Filters of Higher Harmonics presenting in-series resonant contours “capacitance-inductance” connected to the busbars of 6-10 kV allow reducing the distortions entered into a curve of supply voltage by valve converters. Whereby capacitors of filters are the sources of reactive power at a frequency 50 Hz, what is of great importance accounting low power factor of valve converters.

Application:

to reduce curve distortions of supply voltage and current of frequency 50 Hz, as well as for reactive power compensation of grid.

* Approved upon delivery.
In filter designation: first number – number of harmonic;
second number – rated voltage in kV;
third – rated power in kVAr.
Power filters are completed with KEPF capacitors.
Filters have a protection degree IP21 – for input cells and protection,
IP00 – for other parts of filter (enclosing is made by the customer at the place).
If filters with other characteristics are required, we are ready for constructive consideration of the customer’s requirements.
