Abstract

Short circuit fault analysis is needed to determine the amount of short circuit current flowing in a system. This study discusses the single-phase short-circuit current to the ground at the point where the disturbance occurs from the base of the network to the end of the Malewang feeder network. The purpose of this study was to determine the amount of short circuit fault current in the Electric Power Distribution System at PT PLN (Persero) UP3 South Makassar ULP Kalebajeng. This study used the ETAP program and manual calculations. The results of the study found that the contribution of the largest single-phase short-circuit fault current to the ground in the Malewang feeder occurred on Buses located at the base of the network close to the Substation, namely Bus 1 (Exim-Rec Kalaserena) of 0.311 kA, while thesmallest Buscontribution occurred on Buses located at the end of the network far from the Substation, namely Buses 14 (Bilonga) of 0.292 kA. From the results of the study, it can be concluded that the farther the interference bus is from the Substation, the greater the channel impedance. The greater the impedance, the smaller the short-circuit current.

Abstract

This study aims to design, implement, and evaluate a real-time electrical energy consumption monitoring system in the Haji Rani Building using the Arduino Uno microcontroller and the Blynk platform. The system integrates the PZEM-004T sensor for measuring voltage, current, power, and electrical energy, while the Wemos D1 Mini facilitates wireless data transmission via a Wi-Fi network. The research follows a Research and Development (R&D) methodology with a prototype development model. Data collection techniques include observation, documentation, and direct testing. The test results indicate that the developed system has a good level of accuracy, with an average deviation of 4.21% compared to standard measuring instruments. Despite minor deviations, the system successfully provides real-time monitoring with a fast response through the Blynk application, enabling remote access. Functionality evaluation using the Guttman scale, conducted by two content experts, confirms that the system meets the expected standards in terms of reliability, accuracy, and usability. However, the system's reliance on a stable Wi-Fi connection may affect monitoring reliability in areas with poor network coverage. Additionally, the accuracy of the PZEM-004T sensor, while acceptable for general monitoring, could be improved with more precise sensors. Future research should focus on integrating more accurate sensors, implementing machine learning algorithms for energy consumption analysis, and developing an automated IoT-based energy management system. By addressing these aspects, the proposed system can be further enhanced to improve energy efficiency and sustainability.
