Mr Njabulo - Term Paper

But considering that SF6 is costly, it would be ideal so strike a compromise and choose the mixture of 80% N2 and 20% SF6, bearing in mind that experimental measurements for the mixture prove that there is synergy in mixing N2 and SF6, therefore the breakdown will be even greater than predicted 575 kV. 3.
