Extra High Voltage substation grounding|grounding calculation|Touch voltage|Step Voltage|GPR

Extra high voltage substation grounding calculation is one of the most critical calculation in electrical engineering. Generally neutral of EHV system i.e. voltage of and above 66 kV are solidly earthed. It causes huge amount of earth fault current. This earth fault current when returns to the substation ground grid causes huge Ground potential rise which appears at the earthed structures also. But the surface remains at lower potential due to the field effect of the charged conductor. This potential difference becomes fatal for human, so let's see how we can eliminate this hazards. #ElectricalTechnologyAndIndustrialPractice, #EHV_Grounding, #Grounding Grounding EHV substation grounding extra high voltage system grounding grounding of power plant grounding of EHV substation ground potential rise GPR how ground potential rises what is GPR what is ground potential rise touch voltage touch potential step voltage step potential what is touch voltage what is step voltage Please Like, share, comment and subscribe to our channel.
