Contactor Option (C)
The Contactor Option includes a single contactor, which allows the VFD user to control the insertion of
this circuit through the use of a relay contact in the VFD. The customer will supply a separate 120v
source to a terminal block which feeds the contactor. It is recommended that the VFD contact be
programmed to open the contactor below 33% motor power. For variable torque (fan) loads this will be
approximately below 70% speed, so the at-speed contact may be used. This reduces the possibility of
leading power factor interacting with other devices on the power system. Contactor logic should also
maintain the contactor closed in cases where the VFD is bypassed and the filter is not bypassed.
Contactor
The HSD is a drive-applied harmonic filter designed and developed by TCI to reduce the harmonic
currents drawn from the power source by VFDs. The published HSD voltage, Power (Hp or kW) and
current ratings apply to matching power (Hp or kW) rated standard VFDs with six-pulse diode bridge
rectifiers. The HSD may also be sized to filter other loads such as SCR six-step drives, SCR Direct
Current (DC) motor drives, thyristor furnaces, battery chargers, electroplating supplies or other types of
non linear loads. In many cases the filter power rating (Hp or kW) will differ from load power rating
(Hp or kW). Please contact TCI Technical Support for additional information and support on sizing HSD
harmonic filters for your non six-pulse diode front end VFD applications.
The HSD harmonic filter is a passive filter connected in series with the input terminals of a VFD or
several VFDs that operate as a group. It is designed to provide a low impedance path for the major
harmonic currents demanded by the VFD. The filter is a stand-alone device that can be furnished in its
own enclosure and mounted adjacent to the VFD.
The HSD Contactor Option consists of the following standard features and components:
•
A KDR tuned series reactor.
• A TCI 3-phase tuning reactor specifically designed for the HSD filter.
• High-endurance, harmonic-rated capacitors.
•
Bleeder resistors to ensure safe capacitor discharge upon filter shutdown, located on
capacitors.
• Contactor
