The invention is an electrical energy storage type filter which is useful for attenuating harmonic distortion, modulation at high frequencies, line voltage transient sags and surges. The invention structurally consists of a inductance capacitance tank circuit having resistive components and with a resistive element connected in series with the tank circuit. The circuit is tuned to include in its bandwidth the fundamental frequency of the power source and includes in its design consideration of the reactance of the source.
