Abstract
In distribution networks, the grounding point is often led out from the HV side of zigzag grounding transformer and equipped with arc suppression coil to limit single-phase earth fault current to ensure power reliability and safety. By research on the effect of various grounding modes on ration test of zigzag grounding transformer, the paper analyzes the causes for different test results in different connection modes and proposes the reasonable connection mode and precautions for ration test of zigzag grounding transformer.关键词
