Iron cored reactors have the advantage of economy and compactness over air cored reactors. If designed with care linearity characteristics of iron cored reactors can comfortably meet the demand on their performance characteristics for use in resonating and harmonic filters.
The added advantage in iron cored construction is the ease of mounting in panels without the fear of eddy and cross flux paths. They can be made in three phase construction also adding to economy.
PPT makes iron cored reactors up to LI² rating of 1400.
