Abstract: A fault of transformer ironcore multipoint grounding was introduced. The fault was be confirmed by three ratios method. Due to that the transformer can not outage, the treatment method of adding currentlimiting resistor was adopted. Then, not only the growth of the grounding fault was be inhibited, but also a nonplanned shutdown accident was be avoided.
Key words: transformer, iron-core, multipoint grounding, three ratios method
