The results of this study are expected to be useful as basic electrical resistivity data for predicting the ground conditions and evaluation of the ground behavior that is containing sandy fillings in the rock joint for tunnels. WebApr 13, 2024 · So a 100m anode segment with this rating would have an expected life of 127.5 Amp-years. If this anode were operated at 5.1 amps (full rated capacity) it would be expected to operate for 25 years. IF it were operated at 2.55 amps (50% of rated capacity) it should last 50 years. The anode life is generally linear.
