ABSTRACT Fuse has an important role in protecting electronic devices from overcurrent disturbances. One of electronic device that uses a fuse as a means of protection is the AVR. The AVR on the Koto Gasib 25 MW PLTMG can be damaged due to the failure of the fuse to protect against short circuit fault currents from the feeder. The damage that occurred to the AVR due to the failure of the fuse in…
ABSTRACT In recent time, the use of renewable energy as a resource for electronic devices continues to increase. The process of extracting energy from the environment to produce electricity is called energy harvesting. This energy can be obtained from various sources in the environment, such as heat energy, mechanical energy, and radiant energy. Among the available environmental energy sources…
ABSTRACT Three-phase induction motors can experience an unbalanced stator impedance state in each phase. It is necessary to test the effect of these conditions on the performance, stator current, rotational speed, and efficiency of the induction motor. The research method used is to determine the fixed parameters of voltage (V), frequency (Hz), and power (W). Testing of a three-phase induction…
ABSTRACT An induction machine can be operated as a generator or as a motor so that it can be called an induction generator. In a three-phase induction generator with a single-phase output, the loading that occurs greatly affects the value of the output voltage and efficiency. The characteristics of the generator are largely determined by the parameters in the induction generator. The research …
