Abstract
Fault gas seals to prevent the ejection of a surge arrester from a loadbreak bushing due to the generation of such gas in response to the failure of arrester devices in such surge arrester. A metal O-ring support is bonded to the conductive insert of the arrester housing or added as a retrofit to such housing. Annular grooves in the loadbreak probe are fitted with O-rings which are compressed against the support to provide a gas-tight passage along the probe surface. An additional annular groove can be used to receive a fastener to hold the retrofit in position.
