Passive shunt harmonic filters for low and medium voltage: a cost comparison study

This paper presents the cost of 480 V and 13.8 kV passive shunt harmonic filters tuned at 300, 420, 660 and 780 Hz. The cost is presented in function of the kVA of the load served by the filters, the 60 Hz reactive power produced by the filter end the total non60 Hz apparent power of the load. The main conclusion of this work is that for nonlinear loads in excess of 1 MVA it is more economical to use filter centers connected on the 13.8 kV side.
