The choice of Power system neutral grounding is not simply what kind of
grounding issue, which relates to the system over-voltage level, the safe
operation of equipment and systems, protection methods and reliability.
Especially for a higher degree of network cable, because less affected by
external environmental factors, the probability of transient fault is lower. If the
ground fault occurred more than a permanent failure, not self-recovery, and
ground fault occurs after the white could easily lead to insulation breakdown,
resulting in the expansion of the accident. Therefore, the provisions of the
statutes in the country does not allow the cable lines run with a single-phase
ground fault. So that different power system must be based on the specific
circumstances of its power, its existing network and make comprehensive
consideration of future development, with local operating experience to select
a different grounding. Neutral grounding resistance can be effective in limiting intermittent arcing ground over-voltage, over-voltage reduction system, the
system can eliminate resonance over-voltage, easy to configure a single-phase
ground fault protection, can be selectively removed in a short time ground fault
circuit , thereby reducing system equipment insulation level, extend the life of
system equipment, safety and reliability of the system operation is improved. |
