GridHawk® Passive Harmonic Filters (60 Hz)
CTM Magnetics GridHawk passive harmonic filters are a size and cost optimized solution that solves harmonic distortion and guarantees IEEE-519 compliance. The GridHawk filter is specifically designed to handle extreme levels of background voltage distortion of up to 15% THVD without requiring a filter derate. With a built in cooling system, sealed contactors, and a robust capacitor safety circuit, GridHawk filters provide year round peace of mind.

The Optimal Solution for Grid Protection
Grid Protection:
Harmful harmonics are filtered from the inverter input, protecting the grid from VFD produced harmonic distortion.
IEEE-519 Compliance:
CTM Magnetics GridHawk® passive harmonic filters are engineered to meet stringent IEEE-519 requirements for mitigating harmonic distortion. GridHawk® passive harmonic filters are designed for extreme levels of grid voltage distortion ≤ 23% without requiring a derate. Guaranteed performance in even the most demanding environments.
Environmentally Sealed Contactors:
Every contactor used in a GridHawk® passive harmonic filter is installed in an environmentally sealed enclosure. If capacitor contactors are not environmentally sealed, dust & debris have a high likelihood of causing contactor failure. When contactors fail, the capacitors are removed from the filter electrical circuit. This significantly reduces the performance of the harmonic filter, preventing IEEE-519 compliance.
Extended System Life and Reliability:
All GridHawk® passive harmonic filters come with thermal protection for both the capacitors and inductors. CTM Magnetics patented inductor technology and highly efficient film capacitors combined with environmentally sealed contactors, and a robust thermal protection circuit, provide best in class performance and reliability.
TALON™ Protection:
Unlike competitors, our integrated power quality solutions prevent unnoticed filter failures, mitigate harmonic distortion, meet IEEE-519 standards, and aid in avoiding citations from grid enforcement. TALON™; paired with CTM GridHawk Harmonic Filters, deliver comprehensive information and safety measures, guaranteeing optimal efficiency in your power quality operations.
