6 Methods of ground/ earth resistance measurement/Testing
The earth resistance can be calculated using the following formula: R loop = E / I = Rx + (R1 // R2 // R3…//Rn) + Rearth-wire Where E is the applied voltage, I is the current measured, Rx is the resistance sought, R1, R2, R3…Rn are the resistance of electrodes in
Shunt Resistance
Another important parameter is the cell parasitic series (R s) and shunt (R sh) resistance. Green (1982) showed that the major contribution of R s are, the bulk resistance of the semiconductor and resistance of the collecting metallic contacts. The shunt resistance is caused by leakage across the pn-junction due to crystal defects and impurities within the …
