On-Site Inspection Method of Unconventional Mutual Inductor in Intelligent Substation
GU Zheng-zhong · East China Electric Power · 2011
With the construction of intelligent substation,unconventional mutual inductors have been put into opera-tion widely.After running for some time,how to inspect these inductors effectively is arising as a tough problem fa-cing the current inspectors.This paper,combined with operation situation in Shanghai,explored the on-site inspec-tion methods,and proposed that high current impulse be used to inspect unconventional mutual inductor.This new inspection method provides a new way of thinking for the field inspectors.
