Condition assessment of power transformers status based on moisture level using fuzzy logic techniques

Abstract: Power transformers are one of the most expensive components; therefore the focus on their status and its continuous operation is the primary task. In the power systems, condition assessment of performance and reliability is based on the state of components, measurements, testing, and maintenance as well as their diagnosis. Hence, condition assessment of power transformer parameters is important regarding their status and finding incipient failures. Among many factors, the most factors that affect the safe oper… Show more

“…A linguistic variable might be considered a value variable, a fuzzy number, or a variable. The fuzzy logic of fuzzy set theory serves as a foundation for mathematical modeling and language, allowing for the accurate expression of highly advanced algorithms [25]. Fuzzy means blurred or unclear.…”

“…In recent years, researchers have used intelligent techniques such as fuzzy theory (Rexhepi and Nakov, 2018), clustering (Eke et al, 2019), and neural networks (Islam et al, 2017) to fully combine and utilize the condition quantities of transformers, which can eventually assess the current health of transformers more accurately and thus avoid large-scale power accidents due to sudden failures. Many researchers have combined these intelligent techniques and their improved methods with the dissolved gas approach (DGA) for assessing the health of oil-immersed transformers.…”

“…Such smart structure devices help to recognize the operation of transformer equipment and, among other things, affect the safety and diagnosis of its operating parameters. It should be noted that the assessment of the state of electrical, thermal, and mechanical parameters is one of the main elements for defining possible defects in transformers [7].…”
