Gas arresters are hermetically sealed cells in which argon or a mixture of argon and another noble gas, is captured betwen two isolated electrodes. Under defined conditions (e.g.lightening strike, etc) it can become ionised i.e. capable of conducting an electric current. The gas arrester designed for higher powers that has been developed in our laboratory is connected with other electro-elements in a special device that acts protectively in such a way that it diverts the lightning strike to the earth. The construction of the cell is relatively simple no more than four main pieces are joined in a compact compaund, but the procedures are not simple. To ensure high levels of cleanliness and required constant gas pressure in the cell for a period of years, it is necessary to use methods of vacuum-tight joining that are similar to those used for electron-tube production.
