KP Kit Enclosure (9) with Option (0)
The HGP “KP” Option is a harmonic filter component package designed and developed by TCI to
allow qualified customers to build harmonic filters to reduce the harmonic currents drawn from the
power source by variable speed drives. The HGP “KP” Option is available for 200/208, 230/240,
460/480 volt, 575/600 volt systems (60 Hz) and 380 – 415 volt systems (50 Hz). When properly
designed, assembled, and installed, the completed product is intended to be suitable for use with 3
phase diode bridge rectifier loads such as PWM AC drives. I98SCR or thyristor loads such as DC
drives would require a different filter configuration outside the scope of this product offering. Please
contact TCI Technical Support for additional information.
Product Description
HGP KP Kit Option Filter
The HGP KP Kit Option is a package of the primary passive filter components needed to build and
install a harmonic filter on a VFD or VFD system. The filter components are tuned to provide a low
impedance path for the major harmonic currents demanded by the VFD when following the schematic
connections used by TCI in the HGP filter.
The HGP “KP” Option filter component package consists of the following components:
 A KDR input series reactor
 A TCI 3-phase tuning reactor specifically designed for the HGP filter
 KPC panelized, high-endurance, harmonic-rated capacitors
 Bleeder resistors to ensure safe capacitor discharge upon filter shutdown, located on
capacitors
