TCI offers a number of solutions that reduce or eliminate harmonic distortion, including line reactors, passive harmonic filters, and active harmonic filters. With proper application, these harmonic filters are used to meet the IEEE-519 specification on harmonics. They also make products that get rid of unwanted high frequency electrical noise products can cause equipment to malfunction. EMI (Electro Magnetic Interference) and RFI (Radio Frequency Interference) are two types of electrical noise. TCI also makes Output Reactor and Filter products that provide motor protection by limiting voltage spikes below 1,000 volts for long lead applications.
