Abstract: A method for preventing an electrical grid from failure in case of a temporary overvoltage includes providing an electrical grid line, a surge arrester and a disconnector device with a disconnector unit. The method further includes connecting the surge arrester at one terminal to the electrical grid line, connecting the surge arrester at its other terminal to a first terminal of the disconnector device, and connecting a second terminal of the disconnector device to ground potential. The method further includes interrupting the electrical connection in between the electrical grid line and the ground potential in response to a temporary overvoltage. The method further includes protecting the surge arrester from failure due to a thermal overload caused by the temporary overvoltage by operating the disconnector device before the surge arrester fails due to a thermal overload of the surge arrester.

Abstract: The disclosed protector comprises a three electrode gas tube overvoltage protector serially connected with a heating element, the combination being connected in shunt across the load to be protected. Between that protecting shunt path and the source, a normally closed switch is provided which is responsive to the heating element and opens in the event of a sustained overvoltage condition. Accordingly, a prolonged surge which might otherwise destroy the gas tube and/or the protected load is isolated from both the shunt protection branch and from the load thus preventing damage to both.

Abstract: An arrester bypass device can include a switch having an normal state and an operated state. The arrester bypass device can also include a first electrode mechanically coupled to the switch, where the first electrode is held when the switch is in the normal state and released when the switch is in the operated state. The arrester bypass device can also include a second electrode positioned in line with the first electrode, wherein the first electrode contacts the second electrode when the switch is in the operated state. The arrester bypass device can further include a ground strap having a first end and a second end, where the first end is mechanically coupled to the plunger, and where the second end is mechanically coupled to an electrical ground.
