A quality harmonic filter panel is custom-built for the project needs with incremental costs and complexities. In its basic specification, it provides a low impedance parallel path which enables current harmonics from its source at downstream loads to flow into it and allows a tolerable level of current harmonics, within IEEE-519 norm, to flow into the upstream utility grid. However, basic harmonic filters can't control high harmonic levels. Whereas, a top-end harmonic filter mitigates both current and voltage harmonic distortion from any higher level to within limits. When super tuned, the electrical harmonic filter turns a multitasker that eliminates harmonics, maintains power system stability by mitigating power surge, voltage fluctuation, and resonance. A super tuned harmonic filter is an engineering tool that prevents power plant blackout by stabilizing power system parameters for a successful grid de-synchronization, and islanding power generators on utility power failure. Besides, it relives station generators from momentary voltage fluctuations and power surges over a grid or internal power disturbance which helps in eliminating premature winding insulation failure of the generator.
