Component Package Option (CP)
“CP” Option Models
The HG7 “CP” 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 HG7 “CP” 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. SCR 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
HG7 CP Option Harmonic Filter
The HG7 “CP” Option filter components is a package of the primary passive filter components needed
to build a harmonic filter and installed on the input terminals of a variable speed drive or drive system.
The filter components are tuned to provide a low impedance path for the major harmonic currents
demanded by the drive when following the schematic connections used by TCI in the HG7
HarmonicGuard filter.
The HG7 “CP” Option filter component package consists of the following components.
♦ A KDR input series reactor.
♦ A TCI 3-phase tuning reactor specifically designed for the HG7 filter.
♦ High-endurance, harmonic-rated capacitors.
♦ Bleeder resistors to ensure safe capacitor discharge upon filter shutdown, located on
capacitors.
♦ Capacitor mounting brackets that allow for a neat and orderly mounting and connection
of the cylindrical power capacitors.
