Reactive ground
WebIn reactance grounded system, a reactance is inserted between the neutral and ground to limit the fault current as shown in the figure below. To minimize transient overvoltages, the ground fault current in a reactance grounded system should not be less than 25% of the three phase fault current. WebIn the fall, soils in CRP ground generally have very low levels of stored moisture because the established plants have been extracting water actively from the soil during the growing season. Therefore, if rainfall has been minimal in the fall and limited snowmelt recharge took place before crop establishment, probably very little stored soil ...
