Title: Leak testing for over voltage arresters - uses sulphur hexafluoride to penetrate leaky housing and cause detectable breakdown voltage rise
Inventor: SCHULTE AXEL DIPL ING
IPC: G01R31/50
Filed: 1974-04-24
Abstract: The leak testing for over voltage arresters and other sealed and gas filled electrical components is carried out by an apparatus, consisting of a sealed chamber into which the overvoltage arrester is placed. A gas which has a higher breakdown voltage than that of the insulating gas inside the arrester, is then pumped into the arrester housing, the arrester not being evacuated. The gas may be sulphur hexa-fluoride, or a suitable mixture of a gas and air. A test voltage is then applied to the overvoltage arrester. If the arrester housing leaks the sulphur hexafluoride plus air enters the housing (containing e.g. nitrogen) and the arrester breakdown voltage rises. This rise is monitored by a voltmeter across its terminals.
