  • THE NEXT GENERATION OF VACUUM INTERRUPTERS;

    2018-9-10At the beginning of vacuum interrupter technology in the 1960’s 1970’s Vacuum interrupters were deve-loped in a basically empirical manner, with prototype interrupters being built and tested in circuit breakers [3]. Although effective this did not lead to an optimised design, and was expensive particularly in the cost ofCited by: 3
