Description

Following calculations are done as per IEEE 80 or CBIP (India) standards : 1. Calculation of Earth conductor size, 2. Calculation for tolerable Step and Touch potential, 3. Calculation for calculated Step and Touch potential, 4. Calculation of Earth resistance of the earth grid, 5. Calculation of Ground Potential Rise (GPR), 6. Calculation for length of Earth conductor and Earth electrodes. Calculations are performed by MS Excel for uniform soils or by using software for double / multilayer soils. We are performing such calculations on regular basis for substations, transmission lines, generating stations and industrial units of large scale.
