Chinese power industry developed rapidly recent years, and the problem of safety and reliability of power equipment is increasingly outstanding. The development of new test technology and the introduction of artificial intelligence (AI) are driving the monitoring and diagnosing method on insulation condition forward, and nowadays gradually changing the maintenance strategy from breakdown maintenance...
Power transformer is one of the most important components in the power system. The operating reliability of transformers mainly depends on their insulation status. An integrated system which contains the monitoring of gas-in-oil analysis (DGA), partial discharge (PD), contamination of the bushing surface, the equivalent capacitance and dissipation factor (tandelta) of the bushing is introduced in...
In the past decade, CLP Power Hong Kong Limited (CLPP) has initiated the application of a series of condition monitoring techniques on its power equipment so as to allow progressive change of its equipment maintenance strategies from time-based preventive tasks to more condition-based predictive tasks. The data collected from the HV GIS, cables and overhead lines form useful information in maximizing...
Currently, the evaluation of the aging process of HV assets becomes of high strategic importance, where technical aspects as well as economical and social issues have to be taken into consideration. After a general review of the information strategy applied for reliability-centered maintenance (RCM) the submitted paper deals more in detail with an advanced tool for computer-based PD monitoring of...
