Power Transformer Incipient Faults Monitoring

چکیده
Power transformers are important and expensive components in the electric power system. The knowledge of the actual status of the transformer insulation behavior, load tap changer performance, temperature, and load condition is necessary in order to evaluate the service performance concerning reliability, availability and safety. Systems abnormalities, loading, switching and ambient condition normally contribute towards accelerated aging and sudden failure. The paper presents the causes which lead to the internal faults appearance in the power transformer. The production mechanisms of the faults and the on-line monitoring are also analyzed. A monitoring procedure is proposed for the diagnosis and forecasting strategy of the functioning state of the power transformer.

Performance Assessment of Anfis Applied to Fault Diagnosis of Power Transformer
Continuous monitoring of Power transformer is very much essential during its operation. Incipient faults inside the tank and winding insulation needs careful attention. Traditional ratio methods and Duval triangle can be employed to diagnose the incipient faults. Many times correct diagnosis due to the borderline problems and the existence of multiple faults may not be possible. Artificial inte...
متن کاملTransformer Internal Incipient Fault Simulations
Transformer fault detection and diagnosis is becoming more important due to the restructuring of the electric power industry. In this era of deregulation, loading transformers to their optimum capacity is becoming normal practice, which in turn applies high stresses on the insulation of the transformers and increases the probability of occurrence of internal incipient faults. Such faults can le...
متن کاملInter-Turn Fault Detection in Power transformer Using Wavelets
Detection and removal of incipient faults in power transformer winding is essential because minor faults may develop and lead to major faults and finally irretrievable damages occur. This research article presenta a new, simple and incipient fault detection technique, which is based on symmetrical component approach. Using this protection technique, it is possible to detect minor turn-to-turn f...
متن کاملApplication of TLM and Cassie-Mayr Arc model on Transformer Aging and Incipient Faults Simulation
The development of the transformer insulation failure undergoes three stages: insulation aging, incipient faults and a short circuit. This paper presents a complete scheme to simulate single-phase transformers with insulation deterioration and arcing phenomena i.e. in the first two stages. The approach incorporates Transmission Line Methods (TLM), Jiles-Atherton Hysteretic Model, Composite Cass...
