Neptune’s Detuned Harmonic Filtration System is engineered for power factor correction in installations with a high density of non-linear loads. Instead of eliminating current harmonics, it shifts the resonance frequency away from dangerous levels, protecting capacitor banks and network devices. Built with 525V capacitors and single-layer wound AL/Cu reactors offering 200% linearity, it’s available in detuning frequencies of 133Hz, 142Hz, 189Hz, or 210Hz, reducing THD voltage by up to 50%, in automatic or fixed, modular-expandable configurations.
