This research work explores the feasibility of increasing system reliability by applying condition monitoring systems to selected circuit breakers and transformers. Smart grid technology decreases maintenance costs by deploying condition monitoring systems that informs the operator of impending failures or ameliorates those conditions. Since condition monitoring systems can themselves increase operating...
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...
Power transformers are usually very reliable and durable components of the power supply network. Unfortunately, when a fault occurs in a transformer, it can develop catastrophically and failures are usually very expensive, often resulting in the loss of what is the most expensive plant item in a substation [1]. In order to safeguard this valuable asset, various condition monitoring and diagnostic...
