The country's "10th five-year" program---large power transformer state detection and diagnostic system industrialization development obtained breakthrough recently. It is reported that this developmental project was set up in order to solve sophisticated procedure and long and out-of-time detection cycle when electric power operational management authorities manage transformers. In the research and development course, the national university science and technology park adopted independently invented sensor information fusion technology and developed the hi-tech product having single machine and unit integrated in the transformer substation online system. When the project is completed, it is expected to realize the annual output of 200 sets and annual output vale of 35 million yuan, enjoying good industrialization prospect.
