HIGH PASS FILTER RESISTORS


Share this product page:   

High-Pass Resistors are provided with all C-High Pass, High Pass, and Double-Tuned Harmonic Filters.

The resistors are of a stamped stainless steel grid design and are connected in parallel (or across the filter reactor terminals) with the filter reactor to provide resonant damping and a low impedance path for high frequency harmonic currents.

The resistor assembly includes a well-ventilated enclosure that is either roof mounted or rear wall mounted. Roof mounted assemblies utilize 409 stainless steel enclosure and are self-cooled. Rear wall mounted enclosures form an integral part of the harmonic filter enclosure and utilize transformer cooling fans.

Resistor watt rating, current rating, voltage rating, and resistance are chosen based on filter bank damping factor requirements and expected harmonics.
