WebCurrent limiting fuses operate in two modes, depending on the magnitude of the fault current. The first is operation in the overload mode where the fault current is below the threshold current for the fuse. In this mode, the fuse does not operate during the first major half cycle, and does not limit the magnitude of the fault current. WebWhen a grounding bank or a grounding reactor is used to meet the impedance guideline in the previous section, XGB = 0.6pu, the steady state zero sequence current is 0.04/0.6 = 0.067pu. Therefore, the expected phase current generated by the grid voltage imbalance will be about 6.7% of the PV plant rated current. For 480V,
