WebGround referencing electric distribution systems is standard practice in large part to avoid damaging overvoltages, for line‐to‐ground connected loads, which can result from … WebThe voltage to ground that appears at the point of fault. It is the product of ground-fault current and ground-return-path impedance. Ground leakage current (IGL) Current that flows in the system neutral-to-ground connection in an energized un-faulted system. IGL is the result of unbalanced line-to-ground capacitances and unbalanced line-to-ground
