Air Temperature Control System In Silent Generator Box: Sistem Pengontrol Suhu Udara Pada Box Genset Silent
Full text linkFor the community, generators are an alternative if there is a power outage or if there is a large enough electricity demand. According to workers in the field of generator rental in Trenggalek, namely "db Genset" which has the address Ds. Gondang, Kec. Tugu, Kab. Trenggalek, there are 2 types of generators, namely open generators and silent generators, and most people choose silent generators because silent generators are specially designed to muffle engine noise so they don't cause noise, very suitable for use in active environments, but silent generators often experience temperature problems rise (Overheating) which is due to a closed engine and less smooth air circulation. Thus the cooling system on the generator set is needed to support the safety of the temperature on the silent generator so that it remains normal below 70°C which is important to minimize overheating problems in the silent generator, so that it can improve the performance of the generator to work for a long time without any problems. overheating. The design of the Temperature Control System in this Silent Genset Box uses Arduino Uno as a system controller and uses the Ds18b20 sensor, the engine temperature cooling process previously relied on radiator water and radiator fans, so the idea arose to add blower fans on both sides of the silent generator box, marked with a green temperature light indicator. being below 70°C indicates the temperature inside the box is normal, the blue light indicator indicates the temperature inside the box is in the 70°C to 95°C temperature range, fan 1 is on, the red light indicator indicates the temperature in the box is in the 95°C to 120°C temperature range, fans 1 and 2 are on, and the red light indicator indicates the temperature in the box is in the temperature range of 95°C to 120°C if the temperature reaches 120°C the generator engine will turn off indicating the temperature in the box maxsimal fan 1 and 2 remain on until the temperature decreases to 40°C, and every change in temperature will send a notification via SMS to the generator operato

Detection of Stator Winding Short Circuit Faults Through Magnetic Fields In Induction Motors: Deteksi Gangguan Hubung Singkat Belitan Stator Melalui Medan Magnet Di Motor Induksi
Full text linkIn applications in the industrial world, the use of induction motors has been widely used in operation because induction motors have many advantages, although they have many advantages, induction motors themselves also have disadvantages, namely having high starting currents. In many cases the damage to the induction motor, the damage to the stator due to a short circuit, is a frequent failure, this damage can cause considerable losses because the motor can stop operation So this research will discuss about the detection of short circuit faults in the stator winding through leaky flux using a flux sensor that is placed outside the motor and placed radially and using the Fast Fourier Transform (FFT) method. Damage to the short circuit is done by reconstructing the stator winding of the induction motor. There are two variations of short circuit damage, namely short circuit winding 1 to winding 3 and short circuit winding 2 to winding 10 on an induction motor. The short circuit data is then processed using the Fast Fourier Transform method which produces data in the form of voltage to frequency. The results of the percentage of success of short circuit fault detection seen from the loaders have an average percentage of 50%, at no load conditions can detect short circuit faults by 100%. In conditions of short circuit interruption 1-3 has a success percentage of 30% and short circuit fault 2-10 by 70%. The existence of this system is expected to be able to anticipate any damage that can cause considerable and fatal losses
