Juan Liu · 2014
Transformer is one of the power system is more important part of its stable operation is directly related to the normal operation of the system. However, due to various factors, often occur after the core issue multi-point grounding transformer into operation, to a certain extent, affected the reliability of transformer operation. Based on this, on the 220 kV transformer core multi-point grounding hazards and their causes are analyzed and presented on the basis of diagnostic methods and treatment measures in order to help repair the transformer.
