HIGH VOLTAGE FILTERING AND PROTECTION CIRCUIT ABSTRACT OF THE INVENTION A high voltage filtering and protection circuit that is particularly useful in multilead distribution systems, that include a live, a neutral and a ground line. Transient voltage suppressors are connected from a common node to each of the lines. The suppressors are advantageously silicon diode transient voltage suppressors suitable for high voltage applications, clamping at a rated voltage in one direction and having a forward diode characteristic in the other direc- tion. Each suppressor may be paired with a parallel filter capacitor protected by its diode from surges or transient voltages. The paired suppressors and parallel filter capacitor where polarized capacitors are utilized provides an AC equiva- lent capacitor. In one arrangement, a gas discharge tube is provided in series with the suppressor that is connected from the common node to the ground line. In another arrangement with or without the gas discharge tube, the suppressors are bidirectional devices with a rated clamping voltage equal to less than the peak line voltage and a predetermined amount greater than one-half of the peak line voltage. -1-
