An induction motor has an auxiliary coil and a capacitor connected in series in a permanen capacitor motor. The problems that exist in single-phase induction motors the lack of optimization of the performance of induction motor and the importance pf knowing so that they can protect single-phase induction motors from damage and archive optimization and performance of induction motors. The author…
Electrical energy has become the primary need of society for everyday use. By the law of the conservation of energy, electrical energy can be derived from other energy using a device called a transducer. A transducer is a device that can convert force, mechanical transfer or other energy into electrical energy. Piezoelectric is a material that will generate an electric field when pressure or me…
Vegetable oil is needed as an alternative insulating oil to replace mineral oil, because mineral oil can not be renewed and is not environmentally friendly. For this reason, research was carried out by testing the breakdown voltage in a mixture of the two types of vegetable oil in the hope of increasing the breakdown voltage. The test samples used in this study were sunflower oil and canola oil…
Electricity will become increasingly important in people's lives over time. This is because almost all human activities rely on electrical energy, especially in the current modern era where technology is involved in every aspect of life.
