ABSTRACT:
An electrical filter apparatus for an electrostatic precipitator, wherein the filter apparatus is a T-type or pi-type filter electrically connected to a high voltage output of an electrostatic precipitator power supply and an electrostatic precipitator electrode. The T-type filter comprises a first inductor electrically connected to the high voltage output and a capacitor that is also electrically connected to ground. A second inductor is connected to the first inductor and the electrostatic precipitator electrode. In another embodiment, a two-stage inductor assembly is provided having a third inductor member defined by a plurality of turns of a continuous length of wire, and a fourth inductor member defined by a plurality of ferrite beads in end-to-end relationship.
