  • Abstract
    The multigrounded neutral system for power systems above 600 V is a reasonable and safe design. The multigrounded neutral system provides 1) safety, 2) low zero sequence impedance than the single-point grounded neutral system, 3) lightning-arrester sizes can be optimized, 4) freezing and arctic conditions have an adverse impact on the zero sequence impedance, 5) cost of equipment for the multigrounded system is lower.
