A filter circuit for reducing electromagnetic interference in an ungrounded three phase delta electrical system. The filter circuit includes a low pass filter associated with each power phase having one input and output terminal placing an inductor in series with a phase conductor from a power supply. Input and output capacitors connect to a second input and output terminals respectively. An inductor connects in common between the second input and second output terminals thereby to complete a loop that is isolated from ground. Voltage suppression circuits connect from each phase to ground on the input side of the filter.
