ABSTRACT:
An overvoltage protection device for metal-encased, gas-insulated high-voltage lines is disclosed. The device includes a low pass filter which comprises an inductance connected in series with the inner conductor of the high voltage line, and a capacitance connected between the inner conductor and the grounded casing. The inductance and capacitance form the low-pass filter which serves as a trap for high-frequency traveling waves. The invention is especially suited for protection of metal-encased and gas-insulated high-voltage lines and installations in conjunction with a conventional overvoltage arrester.
