Accurate assessment of oil and fault diagnostics electrical power transformer insulation for lifelong endurance are the key issues addressed in this research. The durability of a transformer is significantly determined by the quality of its insulation oil, which deteriorates over time due to temperature fluctuations and moisture content. Protecting...

1 Introduction The Photovoltaic system is the most known of solar energy kinds. Solar energy is exploited by utilizing solar electric systems; the word photovoltaic is originated from the photo (light) and voltaic (voltage). The PV cell straightway converts the sunlight into electrical energy by the PV effect. Since a standard PV cell produces abou...

In standalone photovoltaic (PV) inverter a total cost and harmonic content are most two problems that should be satisfied. In general, the main problems of square and modified sine wave inverters are a higher harmonic content and present the low frequency (LF) or higher frequency (HF) transformer in its configuration. For this reason, this paper pr...

The urgency and problems of instrumental studies of the density and composition of the upper atmosphere (ionosphere) are shown, which consist in the absence of instrumental means of direct measurements of the composition electron-ion trap combined density sensor of the atmosphere at altitudes from 150 to 500 km. In this article describes the possib...

The Internet of Things (IoT) is used in our daily lives, thus this type of technology greatly affects various environments such as smart home, smart cities, and industrial systems. Through IoT, daily objects will be able to interact and interconnect to gather information and automate specific tasks. An IoT framework is a group of guiding rules, pro...

An HVDC transmission system has a converter transformer as one of its main components. The failure of the converter transformer is one of the major concerns for electric power utilities all over the world. Invariably, the top portions of the secondary windings of the converter transformers fail whereas the primaries are left unaffected. In this wor...

Abstract. Accurate faults diagnostics and oil insulation evaluation of electrical power transformers for life-long endurance are the key issue. The durability of transformer function is significantly decided by the quality of insulation oil, which deteriorates over time due to temperature fluctuations and moisture contents. Precise determination of...

Abstract: A physical protection system (PPS) integrates people, procedures, and equipment for the protection of assets or facilities against theft, sabotage, or other malevolent human attacks. The design of an effective PPS requires a methodical approach in which the designer weighs the objectives of the PPS against available resources, and then ev...

Abstract— Accurate diagnoses of faults in power transformers for life-long maintenance is ever-demanding. Transformers insulation excellence is known to deteriorate over time because of temperature fluctuations and moisture contents, which significantly affects its durability and functionality. Developing an intelligent program for precise and effi...

The search for determining accurate faults and assessing the oil quality of high voltage electrical power transformers for life-long maintenance is ever-demanding. The durability of transformers function is significantly decided by the excellence of its insulation which deteriorates over time due to temperature fluctuations and moisture contents. T...

Dissolved gas analysis is a common method for diagnosing faults in electrical transformers and determining the type of faults early on, depending on the specific standards used. Applying dissolved gas analysis methods can be used in diagnosis and in the evaluation process. There are many methods used in the diagnosis of faults in power transformers...
