Abstract

Electricity is a fundamental source of energy that supports daily human activities across residential, commercial, and industrial sectors. As urban development and population growth continue in cities like Binjai, the demand for electricity is steadily increasing. Efficient management of electrical energy usage is crucial to ensure sustainability, reduce environmental impact, and maintain cost-effective energy supply systems. This study aims to analyze the level of electric power usage and the total duration of electricity consumption across various consumer categories in Binjai City. A descriptive quantitative approach is applied by collecting data from utility consumption records, calculating average power usage (kW), total energy consumed (kWh), and determining usage intensity based on national standards. The results indicate that household consumption accounts for the highest usage time, while industrial consumers exhibit the highest average power demand. Several households fall into the high Energy Consumption Intensity (ECI) category, suggesting potential energy inefficiencies. The study emphasizes the importance of awareness, consumption monitoring, and load management strategies to promote energy savings. The findings of this research can be used by local authorities and energy providers to improve electricity distribution planning, encourage responsible usage behavior, and support the development of sustainable urban energy systems.

Abstract

Disruptions in the electricity distribution network are one of the main problems that can reduce the reliability of electricity supply to customers. PT PLN ULP Balige as a customer service unit has the responsibility to ensure the continuity and quality of electricity distribution services in its operational area. This study aims to analyze the main causes of electricity distribution network disruptions using the Fault Tree Analysis (FTA) method. This method is used to identify the root causes of disruptions with a deductive approach arranged in the form of a fault tree. The data used in this study were obtained from disruption reports over the past year that occurred in the medium and low voltage distribution network at PT PLN ULP Balige. The results of the analysis indicate that several dominant factors causing disruptions include equipment component damage (such as transformers and cables), weather disturbances, and other external factors. With FTA modeling, logical relationships between causes can be systematically mapped, thereby facilitating the evaluation process and technical decision-making. This study is expected to be a basis for PT PLN ULP Balige in formulating prevention strategies and improving the reliability of the electricity distribution system through a more structured analytical approach.

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

This study aims to optimize the performance of the distribution substation in maintaining the stability of the electricity network, especially in reducing the effects of voltage drops in the Kuta-cane Customer Service Unit (ULP). Significant voltage drops can affect the quality of electricity supply and cause instability that impacts the performance of customers' electrical equipment. This study includes data collection on distribution substations and network conditions, voltage drop measurements at critical points in the network, and voltage distribution simulations using electrical analysis software. Based on the results of the analysis, optimization of the distribution substation was carried out by adjusting the transformer capacity, installing load balancing devices, and rearranging the load distribution to reduce voltage drops. The optimization results showed an increase in voltage stability in the Kuta-cane ULP electricity network, as indicated by a decrease in voltage drops in previously problematic areas. This optimization has proven effective in maintaining distribution stability and improving the quality of electricity supply to customers. This study produces technical recommendations that can be implemented by the Kutacane ULP in maintaining the performance of distribution substations sustainably, so as to improve the reliability of the electricity network in the region.
