产品概述Product description

        Harmonics (above 1kHz) interference in higher frequency bands are specifically manifested as zero-crossing noise, PLC program operation errors, data errors, time errors, crashes, restarts for no reason or even cause permanent damage.

        The IVD-HPD harmonic protector can absorb harmonic interference of 1kHz and higher frequency bands, eliminate harmonics at the source, and automatically eliminate random high-order harmonics and high-frequency noise, pulse spikes, surges and other interference generated by electrical equipment. Therefore, the harmonic protector can purify the power supply, protect the electrical equipment and power factor compensation equipment, and prevent the false tripping of the protection device, thereby protecting the equipment to operate safely, stably, and reliably.

        更高频段的谐波（1kHz以上）干扰，具体表现为过零噪音，PLC程序运行错误、数据错误、时间错误、死机、无故重新启动甚至导致永久性损坏。

        IVD-HPD谐波保护器能吸收1kHz以及更高频段谐波干扰，将谐波消除在发生源，自动消除对用电设备产生的随机高次谐波和高频噪声、脉冲尖峰、电涌等干扰。因此通过谐波保护器能够净化电源、保护用电设备和功率因数补偿设备、防止保护装置的误跳闸，从而保护设备安全、稳定、可靠地运行。
