Abstract

The decline in power performance in generators can be caused by various factors, one of which is the degradation of the stator conductor windings due to age, excessive temperature, or unstable operational conditions. This study aims to analyze and improve the power performance of a 20 kVA generator through the rewinding process of the stator windings with new conductors that meet technical standards. In this study, the methods used include initial analysis of the condition of the old windings, planning the winding redesign, the rewinding process, and testing the results through measuring voltage, current, efficiency, and power factor. The test results show a significant improvement in generator performance parameters after the rewinding process. The output voltage becomes more stable, power losses decrease, and efficiency increases from 0% to 80%. In addition, the power factor has improved from 0 to 0.92. This improvement proves that the rewinding process with the right material and technical specifications can restore and even significantly improve generator performance. This study makes a real contribution to the maintenance and reconditioning of electrical equipment, especially in small-to-medium scale power generation systems.

Abstract

Indonesia has the potential for new and renewable energy (EBT), including solar energy as a source of power generation. Energy efficiency can be defined as the ratio between the electrical power generated and the input power received. Low efficiency impacts the electrical power output of solar modules. This underlies the use of Solar Power Plants (PLTS) as a new and renewable electrical energy source to replace fossil fuels that have limited quantities and pollute the environment. Solar cells as PLTS units have the constraint of insufficient output power and are highly dependent on natural conditions. One method of optimizing solar cells is by using sunlight-reflecting glass (reflectors). Sunlight is a renewable energy source that can be utilized as a new power generator. However, in the process, certain additions are required to the solar cell module to optimize the output voltage produced. Efforts to optimize electrical output in solar modules by maximizing the intensity of light falling on the surface of the solar module by using direct sunlight. The results obtained are in the form of a comparison.

Abstract

The development of electric vehicle technology continues to experience rapid progress, especially in terms of energy efficiency and power storage systems. One of the main components in an electric vehicle is the battery, which plays a crucial role in determining the vehicle's range, performance, and energy efficiency. This study aims to analyze the battery life of a BLDC (Brushless DC) motor used in a mini electric car prototype. Testing was conducted at the Electrical Engineering Laboratory of Panca Budi Development University with various load scenarios and operating times to evaluate battery life performance. The research method was carried out through an experimental approach by directly measuring voltage, current, temperature, and operating duration using a digital measuring instrument and periodically recording the data. The test results showed that the battery has optimal performance within a certain current range, but experienced a decrease in capacity as the load and operating temperature increased. From the test results, it was concluded that battery life is greatly influenced by operational conditions and charging system management. This study provides an initial overview for the development of a battery management system (BMS) and energy efficiency design in a laboratory-scale mini electric vehicle. Development recommendations are directed at temperature control and load power regulation so that the battery can be used more optimally and sustainably.

Abstract

Low grounding resistance is an important factor in ensuring the safety and reliability of electric power systems, especially on High Voltage Overhead Lines (SUTT). This study aims to analyze and improve the grounding resistance values on 150 kV SUTT towers on the Glang–Namorambe line using the three-point measurement method. Measurements were conducted to determine the actual condition of the grounding system and evaluate the effectiveness of the improvements made. Initial measurements showed that several towers had resistance values exceeding the maximum PLN standard limit of 10 ohms. To address this, improvements were made by installing additional electrodes, adding conductors, and using ground enhancement materials. After the improvements, remeasurements were conducted for each tower. The analysis results showed that the applied improvement method succeeded in reducing the grounding resistance value significantly, with an average reduction of 40–60%. The final resistance values of all towers were below the specified threshold, so that the grounding system can function properly in protecting equipment and personnel safety from overvoltage disturbances caused by lightning and ground faults.

Abstract

Distribution transformers are crucial components in power distribution systems that require real-time monitoring to prevent disruptions and ensure efficient operation. Internet of Things (IoT)-based monitoring systems offer innovative solutions with the ability to detect disruptions early and provide real-time information to operators. This study proposes an optimized early-detection monitoring system for distribution transformers by utilizing IoT devices, including temperature, pressure, and humidity sensors installed on the transformers to monitor their operational conditions. Data collected through the sensors is then processed using a cloud platform for further analysis, with machine learning algorithms used to detect anomalous patterns indicating potential disruptions. Furthermore, the system is designed to send automatic notifications to operators via a mobile application or web dashboard when a disruption is detected, enabling faster response and prevention of further damage. Test results show that the system is capable of detecting disruptions with high accuracy and can improve maintenance efficiency and reduce transformer operational downtime. The implementation of IoT in distribution transformer monitoring also opens up opportunities for optimizing condition-based maintenance management that is more economical and proactive.

Abstract

This research analyzes the efficiency comparison between the Auxiliary Power Unit (APU) and Ground Power Unit (GPU) on the Airbus A320 aircraft's electrical system during ground operations. Aircraft operations require a stable power supply, provided by either an internal APU or an external GPU. Although the APU offers flexibility, its high fuel consumption and significant environmental impact are considerable concerns. Conversely, the GPU is deemed more efficient and environmentally friendly. The study aims to calculate energy consumption, analyze efficiency, and recommend the most efficient and environmentally sound electrical power source. The method employed is a quasi-experimental field observation, involving direct data collection from a Houchin LTD model C690 GPU unit. Data collection was conducted over 7 days, from June 1 to June 7, 2025. Data analysis includes mathematical calculations for energy efficiency and operational economic analysis. Research findings indicate that the GPU significantly outperforms the APU. The diesel GPU exhibits an energy efficiency of approximately 31.30%, considerably higher than the APU's around 1.54% (based on 7 days of data). The GPU also presents superior electrical power quality, characterized by a higher Power Factor and lower Total Harmonic Distortion (THD). It is recommended that airlines prioritize GPU usage, and airport authorities expand Fixed Electrical Ground Power (FEGP) infrastructure to enhance energy efficiency and reduce operational costs.

Abstract

Switched Reluctance Generators (SRGs) have attracted attention due to their robust construction, low cost, and high fault tolerance, suitable for extreme environments. However, SRGs suffer from torque ripple and acoustic noise due to the non-linear torque-excitation current relationship. Although SRG component optimization has been investigated, a gap exists in the analysis of the effect of stator excitation current on the drive torque in a single-phase "6/6" SRG design with external amplification. This study analyzes the impact of varying stator excitation current on the drive torque of a single-phase 6/6 SRG. The methodology includes design, finite element analysis (FEA), and testing of an initial drive torque prototype. Results show that increasing the stator coil supply voltage results in a greater magnetic force, which counteracts the mechanical torque on the rotor shaft. This understanding is crucial for optimizing torque performance, mitigating ripple, and improving SRG efficiency for future applications.

Abstract

Penelitian ini menganalisis instalasi sistem kelistrikan pada perencanaan pembangunan gedung industri PT. Growth Asia berfokus pada kesenjangan antara prosedur formal dan praktik lapangan. Pasokan listrik yang tidak stabil dan instalasi sementara berisiko tinggi menyebabkan downtime, penurunan produktivitas, dan kecelakaan kerja. Menggunakan metode deskriptif kuantitatif dengan pendekatan studi kasus, penelitian dilaksanakan selama tiga bulan (Juli–September 2025) di Kota Medan. Data dikumpulkan melalui observasi terstruktur, kuesioner, dokumentasi proyek, serta catatan gangguan listrik, dan dianalisis menggunakan statistik deskriptif, uji korelasi Pearson, serta paired sample t-test. Hasil menunjukkan bahwa terdapat kesenjangan antara pemahaman teknisi di lapangan dengan standar teknis isolasi (PUIL/IEC), yang mendorong praktik normalisasi deviasi seperti penyambungan tanpa prosedur standar. Korelasi negatif sedang ditemukan antara kualitas isolasi kabel dan kestabilan sistem listrik (r = -0,574), sementara uji t menunjukkan peningkatan kualitas isolasi secara signifikan menurunkan gangguan kelistrikan (p = 0,00026). Penelitian ini merekomendasikan penguatan pengawasan lapangan dan pelatihan teknis sebagai upaya peningkatan keselamatan kerja dan efisiensi sistem kelistrikan proyek konstruksi.
