Abstract

The power factor cos phi measures the efficiency of using electrical power in a system. A low power factor indicates the presence of high reactive power consumption, which can lead to increased energy losses and operational costs. To overcome this problem, an effective power factor regulation system is required. This research designed and developed the Cos Phi Trainer, which operates in two modes, manual and automatic, to improve the power factor at an electrical load. The system is designed to give users a practical understanding of measuring and improving power factors by setting up compensation capacitors. In manual mode, the user directly sets the value of the capacitor used to fix the power factor. While in automatic mode, the system uses current and voltage sensors to measure the power factor value in real-time and automatically adjusts the capacitor to achieve the optimal power factor. The trainer has an easy-to-use interface and a measurement panel that displays important parameters such as current, voltage, active power, reactive power, and power factor. The test results show that the system can significantly increase the power factor in manual and automatic modes. Thus, this Cos Phi Trainer is an effective tool for training in the laboratory of Indorama Engineering Polytechnic and teaching about electrical power management and energy loss reduction in the electrical system.   Keywords: Power factor, manual, active power, reactive power, trainer

Abstract

Transportation is the most important need in the mobility of fulfilling people's needs. The increasing number of transportation has an impact on environmental degradation, especially air pollution. Based on the Ministry of Environment and Forestry (KLHK), transportation contributes more than 20% of the total Carbon Dioxide (CO2) emissions in Indonesia. This is caused by conventional transportation or vehicles that use oil fuel (BBM). In addition to polluting the air, the use of conventional vehicles also triggers respiratory diseases that will worsen the quality of human life. Electric cars are one solution to overcome this problem because electric cars do not emit carbon emissions. Electric cars continue to be developed through industrial technology research including fast charging circuit architecture topology, power flow, and protection. Fast charging or fast charging of electric car batteries is needed to increase comfort, efficiency, and speed up time. Electric cars that have been designed by the Electrical Technology of the Indorama Engineering Polytechnic require a compatible fast charging circuit. The study aims to analyze the effect of Integrated Circuit (IC) 7805 and IC 7812 on fast charging of electric battery cars. The results of the study showed that the best performance criteria were obtained in the fast charging circuit using the IC 7805. A more stable voltage profile compared to circuits without IC, with an average of 12V. The current flowing is also high, which is 4 amperes, compared to other circuits, so that the charging time is faster, which is 8.75 hours compared to the circuit without IC, which takes 9.64 hours to charge the battery. Therefore, the addition of IC 7805 is proven to be compatible in the fast charging circuit of electric car batteries.

Abstract

Electronic equipment created today is synonymous with the use of electricity as an energy source. This will lead to an increase in the use and demand for electric energy for the use of electrical equipment every day. In addition, the availability of electrical energy is currently limited. These conditions require to economize on the use of electricity. Savings can be made when someone knows how much energy is used every day. To overcome this problem, a measuring instrument was designed in the form of a Wattmeter which has a real-time measurement system that can monitor the use of electric power every day through this tool and measurement data can also be accessed via a smartphone. This wattmeter uses an all in one sensor, namely the Hlw 8012 energy meter to measure RMS current, RMS voltage, and VA RMS equipped with Clock and PWM. From the results of these data will be uploaded to a cloud and then monitored through the blink application which has been designed to display data in the form of numbers and graphics according to the results on the tool. The results of measurement and monitoring of the tool that has been made using the Hlw 8012 sensor by obtaining 2 sensor data values ​​(current and voltage) are obtained for very good voltage values ​​between 0 - 2%, while for current values ​​reaching 5-10%. Error error in the current value due to the pulse output from the HLW8012 IC, thus causing an error in the power value, as well as the tolerance value of the HLW8012 IC of ± 5%.

Abstract

Penelitian ini membahas simulasi dan rancang rangkaian power supply variabel berbasis TIP41C (NPN) dengan pendekatan analisis teoritis, simulasi menggunakan MATLAB dan desain menggunakan Proteus, serta pengujian hasil aktual. Tujuan utama dari penelitian ini adalah untuk membandingkan hasil tegangan keluaran dari ketiga metode tersebut guna menilai tingkat akurasi dan kinerja rangkaian yang dirancang. Proses perancangan meliputi penentuan komponen utama seperti transformator, penyearah, kapasitor filter, serta resistor dan potensiometer sebagai pengatur tegangan keluaran. tahap awal dilakukan menggunakan proteus untuk desain dan memverifikasi fungsi rangkaian secara keseluruhan, sedangkan simulasi MATLAB digunakan untuk melakukan analisis numerik dan validasi model matematis terhadap karakteristik keluaran power supply. Berdasarkan hasil perbandingan antara tegangan output teoritis, hasil simulasi MATLAB, dan hasil pengukuran aktual, diperoleh bahwa simulasi MATLAB memiliki tingkat akurasi tinggi dengan error relatif kecil, berkisar antara 0,40% hingga 0,90% dengan rata-rata 0,67%. Sementara hasil pengukuran nyata menunjukkan error sedikit lebih besar, yaitu antara 0,00% hingga 3,83% dengan rata-rata 1,25%. Selisih tersebut disebabkan oleh toleransi komponen, rugi daya internal regulator LM317, penurunan tegangan pada sambungan kabel dan jalur PCB, serta pengaruh suhu dan ketelitian alat ukur. Secara keseluruhan, hasil penelitian menunjukkan bahwa rangkaian power supply variabel berbasis TIP41C (NPN) yang dirancang memiliki kinerja yang baik, stabil, dan mampu menghasilkan tegangan keluaran yang dapat diatur sesuai kebutuhan

Abstract

Motor induksi tiga fasa merupakan salah satu penggerak utama dalam sistem industri karena memiliki konstruksi yang sederhana, keandalan tinggi, dan efisiensi yang baik. Namun, metode pengoperasian konvensional seperti Direct On Line (DOL) menyebabkan arus awal yang besar serta kurang efisien dalam pengaturan kecepatan motor. Penelitian ini bertujuan untuk menganalisis pengaruh pengendalian kecepatan motor induksi tiga fasa menggunakan Variable Frequency Drive (VFD) terhadap perubahan arus kumparan stator dan kecepatan putaran motor. Metode penelitian dilakukan melalui pengujian eksperimental pada motor induksi tiga fasa dengan variasi frekuensi 5 Hz, 25 Hz, 30 Hz, 40 Hz, dan 50 Hz menggunakan VFD dengan pengaturan potensiometer eksternal. Parameter yang diamati meliputi kecepatan putaran motor (RPM) dan arus kumparan stator (A). Berdasarkan hasil pengukuran Pengujian Tanpa Beban diperoleh bahwa pada frekuensi 25 Hz motor berputar sebesar ±565 rpm dengan arus sekitar 0,43A, pada 30 Hz sebesar ±1000 rpm dengan arus 0,43 A, pada 40 Hz sebesar ±1280 rpm dengan arus 0,43 A, dan pada 50 Hz mencapai ±1450 rpm dengan arus sekitar 0,43 A. Hasil pengujian menunjukkan bahwa peningkatan frekuensi pada VFD menyebabkan kenaikan kecepatan putaran motor secara proporsional terhadap frekuensi yang diberikan. Selain itu, arus kumparan stator tidak meningkat dengan kenaikan frekuens karena motor beroperasi tanpa beban, sehingga arus yang dominan adalah arus magnetisasi yang cenderung stabil  sehingga perubahan frekuensi, namun tetap berada dalam batas operasi yang aman. Dibandingkan dengan metode starting langsung (DOL), penggunaan VFD mampu menekan arus awal motor secara signifikan sehingga meningkatkan efisiensi operasi dan keandalan sistem penggerak motor induksi tiga fasa.
