Abstract

Distribution transformers play a critical role in delivering electrical energy from medium-voltage networks to low-voltage consumers. At ULP Medan Kota, several distribution transformers have been operating with loads exceeding 80% of their nominal capacity, posing risks of overloading, efficiency reduction, and equipment failure. This study aims to analyze the performance of distribution transformers based on actual load data and evaluate mitigation strategies through the implementation of additional parallel transformers (trafo sisip). The methodology includes data collection, load and current calculation, and simulation of load distribution after transformer insertion. The results show that the installation of trafo sisip reduces the load on the main transformer by approximately 50% and significantly lowers the current to safer levels. Moreover, placing the trafo sisip at an optimal position minimizes voltage drop to as low as 0.0745 Volts. Therefore, the addition of trafo sisip is proven to enhance the reliability, efficiency, and operational life of the power distribution system at ULP Medan Kota.

Abstract

availability of sustainable electrical energy is an essential requirement in the campus environment, particularly to support academic activities of students and academic staff in the use of electronic devices such as mobile phones and laptops. Currently, charge station facilities generally rely on conventional electrical energy supplied by the national grid, which has limitations and causes environmental impacts. Therefore, the utilization of renewable energy is an alternative solution that needs to be developed. This study aims to analyze the planning of a Solar Power Plant (Photovoltaic System) as a source of electrical energy for charge stations at Branda Cafe, Universitas Pembangunan Panca Budi. The research method employed is a quantitative descriptive approach, which includes analysis of daily electrical energy demand, charge station design planning, calculation of the number and capacity of solar panels, battery capacity planning, and selection of supporting PLTS components such as solar charge controllers and inverters. The results show that the total daily electrical energy demand of the charge station is 3,600 Wh. To meet this demand, the PLTS system is designed using nine 100 Wp solar panels, three 12 V 100 Ah batteries, one MPPT-type solar charge controller, and a 5,000 W inverter. The designed PLTS system is capable of providing a reliable, independent, and environmentally friendly electricity supply. Thus, the implementation of PLTS-based charge stations on campus can serve as an alternative solution to support sustainable renewable energy.

Abstract

The reliability of medium-voltage (MV) distribution networks is strongly influenced by the performance of protection systems, particularly Fuse Cut Outs (FCO) installed at feeder branches. TPN06 feeder at PT PLN (Persero) ULP Rantau, with a total network length of 15 km and 23 distribution transformers, experienced a high disturbance frequency during August–September 2024, with 8 recorded Auto Reclose Ground Fault (AR GF) incidents. Initial evaluation revealed that most installed FCO ratings were not aligned with the actual branch load currents. Several FCOs were found to be overrated, including Pulau Kutil (4 A adjusted to 2 A), Balai Pesona (4 A to 2 A), Sei Impat (4 A to 2 A), PR Binderang (4 A to 2 A), Jati Makmur (5 A to 2 A), Budi Mulya (5 A to 3 A), and Lokpaikat (25 A to 12 A), while only Bitahan (3 A) and PR Permata (2 A) were appropriately rated. This study aims to evaluate the effectiveness of FCO rating adjustments based on actual load current measurements and three-phase apparent power calculations at 20 kV. The methodology includes disturbance data analysis, peak load current measurement using an ampere clamp, and branch current calculation. The results indicate that adjusting FCO ratings improved protection selectivity and coordination, enabling better fault localization at branch levels. Following the adjustment at the end of September 2024, the disturbance frequency significantly decreased during October–November 2024, reaching zero incidents.
