On the Technology and Management of Substation Maintenance

With the development of national economy, China's needs for electricity are growing and the requirements on quality is also becoming stricter on the power system security, stability and economic operation. Diagnosis of the state of equipment is mainly based on statistical analysis of large amounts of data. But with the development of computer technology and artificial intelligence, a diagnostic equipment is formed like an expert system, replacing the past practice by recognizing equipment malfunction by years of data on tests, operations, maintenance and so on. Comparative analysis is done by repeated calls of accident records. It becomes more accurate and reliable to introduce and apply advanced technologies of condition-based maintenance and management into insulation diagnosis of electrical equipment.
