The IORA 3000 Active Harmonic Filter measures the level of current harmonics in the supply line and eliminates it by generating counter harmonics in real time, using state of the art technology. It is available in ratings up to 600 Amps, the highest in the world. The modular construction is a unique design based on a floating point 32-bit DSP. It offers selective harmonic elimination. CT can be connected to the load or the source. A higher attenuation of up to 96% of individual harmonics is possible. It employs high speed IGBTs in the power circuit and offers PF compensation, both leading and lagging. It helps in complying with power quality regulations like IEEE 519
