Question

Consider a hemispherical grounding electrode of radius 0.5 [meter] is embedded into a two sector earth. The left lower half-space has conductivity σ1-4.0 × 10-3 [Siemens/meter) and right lower half. space has conductivity σ2 = 80 x 10-3 [Siemens meter], The current intensity of the electrode is 1- 100.0 [Amperes]. Determine (a) The grounding resistance of the electrode い↓SSfe5dr ん (b) The power of Joules losses in each of the earth sectors.
