Non-linear loads such as variable frequency drives (VFDs) increase motor efficiency but also introduce substantial harmonic voltage and current distortion, THVD and THID respectively. In certain regions, such as the Permian Basin, the voltage distortion can reach dangerously high levels. Under these levels, most standard 480 V passive harmonic filters, AFEs (Active Front End), and 18 pulse drives fail.
CTM GRIDHAWK® series filters are rated to handle up to 22.5% THVD without failure. All GRIDHAWK® series filters are engineered to help meet the IEEE-519 requirements under full load conditions (5% THID). CTM GRIDHAWK® filters utilize poly-film capacitors because of their better current ripple handling capabilities. CTM GRIDHAWK® filters are available in multiple packaging configurations and come with both air and liquid cooled options.
Due to CTM’s confidence in this product line, all CTM GRIDHAWK® filters come with a 5 year capacitor warranty* and a performance guarantee. This is something none of our competitors are willing to do. GRIDHAWK® filters are built to survive. We guarantee it.
