Product Description
Product Description
HGL Drive-Applied Filter
The HGL 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 HGL 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 HGL 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 HGL
harmonic filters for your non six-pulse diode front end VFD applications.
The HGL 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 drive. The filter is a stand-alone device that can be furnished in its own enclosure and
mounted adjacent to the drive. It is also available on an open panel for mounting within an enclosure
with the drive or other equipment.
The HGL filters consist minimally of the following features and components:
•
A KDR tuned series reactor to prevent system interaction and improve filter
performance
•
An L-C-L filter circuit with:
•
A TCI 3-phase tuning reactor specifically designed for the HGL filter
•
High-endurance, harmonic-rated capacitors
• Larger filters may have multiple tuned circuits. Consult fuse tables to determine if the
filter in question has “parallel” branches.
• Bleeder resistors to ensure safe capacitor discharge upon filter shutdown
•
Cooling fans (on select models) to ensure adequate cooling and safe operating
temperatures
•
Compression terminals for ease and integrity of all power and control wiring
•
Fuses, sized to protect the capacitor wiring
