We sent this to them and ask for clarification, why this happens. But same grid arrangement with same soil model we run calculation in our software, grid design became unsafe.
EARTHING CALCULATION SOFTWARE SOFTWARE
Owner’s engineer did this project with one of the other software mentioned in your article and they got safe result. Unfortunately, we were not able to achieved this with one of the software mentioned in your article. I involved in a power plant project where the above said scenario took place and EPC consultant approved remedies proposed but owner’s engineer not approved and they need a safe design as software output. Luckily no accidents reported in my knowledge. Some clients neglect the remedies proposed.

Some times GPR may high beyond plant boundary. and balances in designing an earthing system due to the complexities of calculation. If it is a thermal power plant this generally happen in water ash disposal or water intake or any remote parts of the plant (of course depends on plant layout). Comprehensive Earthing Grid Designing with CDEGS Design Software. If we do Earthing calculation in FEM method in Etap for irregular shape grid, the Touch voltage exceeds in corner which is farthest from geometric center of earthing grid where as step voltage is within limit. LinkedIn User Drawback of Etap – No soil modelling module IEEE 80 – ‘Guide for Safety in AC Substation Grounding’ and Finite Element Method, the optimum substation earthing design shall be achieved iteratively based on most rational Soil Resistivity Model, fault current calculation and factors.ĭesign Flow specified in IEEE 80 is cited in below diagram. In such scenarios, manually designed earth grid designs as per BS 7430 shall be validated with proven software applications and expertise of experienced consultants.Īpart from MV/LV installations, Electrical Substations are more vital in terms of Step & Touch potentials as the perimeter is prone to higher fault currents.

When we encounter requirements for bonding of electrical installation with Lightning Protection Systems, lower values of Earth Electrode Resistances are mandatory in order to limit potential rises triggered by Lightning activities. When it comes to industrial and commercial installations, the earth systems are substantial with regard to Medium Voltage, Low Voltage Systems and earth termination of Lightning Protection Systems. Ground Grid designs are crucial for any electrical infrastructure in order to ensure safe return path for fault currents and thereby prompting isolation with coordinated detection.
