One of the most serious possible faults in power systems is transformer limited fault (TLF), in which transient recovery voltage (TRV) characteristics is determined by the closest transformer to the circuit breaker and due to the immense variety of t

Methanol concentration as an aging indicator can assess cellulose aging and estimate cellulose degree of polymerization (DP). Despite the advantages of methanol (MeOH), its major disadvantage is that its concentration in the oil decreases after some

Power transformers aging is investigated by a chemical aging model and an electrical-thermal aging model. In the chemical aging model, oil and cellulose chemical status are considered, but transformer load is not considered, while in the electrical-t

Power transformer insulation is degraded and decomposed over time. Due to the importance of cellulose, indicators such as 2-Furfural, CO, CO2, and CO2/CO ratio are used to investigate cellulose aging status because these are cellulose degradation pro

In 1936, Ekenstam derived an equation for cellulose ageing kinetic that linked DP to life and reaction rate. Later, Arrhenius obtained an equation that linked reaction rate to temperature, activation energy and coefficient A. Then, using these equati

Since power transformers are valuable components of power networks, reliable determination of the remaining lifetime of a transformer is very important for power utilities. Power transformers consist of oil, a core, wire, and paper (cellulose), and t
