The Optimal Solution for Harmonic Mitigation & IEEE-519 Compliance

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.
