Abstract

The wood processing industry heavily relies on three-phase induction motors to drive high-power equipment such as chipper machines. One of the major challenges in operating these motors is the high inrush current during startup, which can destabilize the power system and accelerate equipment wear. This study aims to analyze the effectiveness of using a soft starter as a starting method for a 400kW induction motor in a chipper application. The research method is an experimental case study involving direct field observation and theoretical calculations of electrical parameters such as nominal current, current limiting, torque, and trip class. The observation results show that the actual starting current of 1,216.15 A remains below the calculated current limiting threshold of 1,575 A, while the trip class value of 2,835 A provides optimal protection. The use of a soft starter proves effective in reducing inrush current, maintaining voltage stability, and enhancing the reliability and efficiency of motor operation. This research supports the application of soft starters as a suitable solution for high-power motor starting in heavy industrial settings.

Abstract

Penggunaan Pembangkit Listrik Tenaga Surya (PLTS) merupakan salah satu pilihan untuk menghasilkan energi bersih. PLTS merupakan pilihan yang sangat baik bagi keberlangsungan lingkungan. Meskipun kita dapat menggunakan panel surya untuk mengubah energi matahari menjadi energi listrik, penggunaan yang paling banyak untuk saat ini adalah penggunaan PLTS rooftop. Namun, penggunaan PLTS perlu ditingkatkan, terutama karena kita sekarang bergantung pada listrik yang bersumber dari PLN. Oleh karena itu, perlu dianalisa penggantian sumber energi listrik menggunakan PLTS rooftop di sistem SD-SMP Swasta Sabilina, yang saat ini masih menggunakan sumber listrik dari PLN dan generator. Berdasarkan analisis yang dilakukan, SD-SMP Swasta Sabilina memiliki potensi menggunakan PLTS 500 wattpeak sebanyak 728 panel surya dimana PLTS tersebut disusun secara seri dan parelel yang terdapat 28 array serta membutuhkan SCC 380 A dan inverter 16 kW, serta 396 unit baterai berkapasitas 12 V 400 Ah dengan sistem PLTS off-grid

Abstract

The reliability of electric power systems depends significantly on the accuracy of electrical energy metering instruments, as measurement errors directly influence consumption records and the fairness of transactions between utilities and customers. This study assesses the accuracy of kilowatt-hour (kWh) meters installed in three-phase Measuring and Limiting Devices (APP), considering both direct measurement configurations at low voltage (LV) and indirect measurement configurations at medium voltage (MV). The methodology includes field measurements of current, voltage, and power, followed by the calculation of kWh meter errors and Current Transformer (CT) errors using the collected data. The findings show that the kWh meter error is 0.27% for direct measurements and −1.78% for indirect measurements, with an average CT error of 1.97%. All measured error values are within the applicable standard tolerance limits; thus, the kWh meters are considered accurate, reliable, and suitable for operational use.
