Abstract

Saat energi listrik disalurkan, tidak seluruhnya dapat mencapai pelanggan. Fenomena ini dikenal sebagai susut energi listrik. Susut energi ini terbagi menjadi dua kategori, yaitu susut teknis dan susut non-teknis. Faktor Teknis adalah Ketidaksesuaian material yang digunakan dan kurangnya pemeliharaan rutin. Susut non-teknis yang berkontribusi terhadap kerugian tersebut meliputi penyalahgunaan energi listrik serta kesalahan dalam pengukuran, yang sering ditemukan pada kWh meter. Dari hasil perhitungan susut di PLN (Persero) ULP Talang Padang pada bulan Juni 2024 sebesar 6,79%, kemudian mengalami kenaikan pada bulan Juli 2024 menjadi 7,84%. Bulan Agustus mengalami penurunan dari bulan sebelumnya menjadi 7,48%. Dan empat bulan berikutnya mengalami kenaikan terus menerus yaitu September 2024 sebesar 7,92% Oktober 2024 sebesar 8,04%, November 2024 sebesar 11,09% dan Desember 2024 sebesar 11,31%. Dari hasil perhitungan susut dapat mempermudah PT PLN (Persero) ULP Talang Padang untuk mengevaluasi pekerjaan yang dilakukan untuk lebih mengupayakan penurunan susut pada sistem distribusi sehingga penyaluran energi yang akan mendatang lebih efisien.

Abstract

A three-phase induction motor is extensively employed in the industrial sector due to its robustness and cost-effectiveness. An enhancement of this motor is underway to optimize its performance. Enhancing motor performance is intricately linked to escalating motor production expenses. Consequently, an innovative strategy is essential to enhance motor performance without incurring substantial extra expenses. This study aimed to introduce a novel approach for designing 3-phase induction motor coils to enhance motor performance without significant additional expenses. This study concentrated on the design of a 3-phase induction motor coil, rated at 1 HP, 380 V, 2 A, 4 poles, and 24 slots, and arranged in a Y-connection. We fabricated the coil using a dual-layer approach, creating magnetic pole pairs on each layer. The study's results demonstrated an improvement in output power, efficiency, load torque, and rotor speed of the new motor design, specifically by 19.32%, 16.26%, 18.48%, and 0.72%, respectively. Despite a 3.05% rise in motor coil current during peak load conditions, the motor's overall performance significantly improves, enhancing its capabilities without considerable additional expenses. This study claims that the suggested way can make other 3-phase induction motors work better without costing a lot more.

Abstract

This study focuses on analyzing the impact of load imbalance on the MF0001 distribution transformer at PT PLN (Persero) ULP Kersik Tuo, particularly focusing on power losses caused by neutral current and temperature rise. Load imbalance occurs when the current distributed across the three phases is not equal, resulting in the flow of neutral current. This neutral current contributes to significant power losses and causes an increase in temperature at critical connection points, which may lead to accelerated damage to distribution equipment. Measurement data showed that the current in phases R, S, and T were 226 A, 156 A, and 135 A respectively, while the neutral current reached 104 A. The hotspot temperature on phase R was recorded at 105°C, which exceeds the standard operational temperature limit for transformers. To address this issue, load balancing was carried out by shifting loads from overloaded phases to underloaded ones. After balancing, there was a significant decrease in both neutral current and temperature. The power losses were reduced from 11% to below the threshold set by the SPLN 1997 standard, which is 2%. The results of this study demonstrate that load balancing is an effective technical solution to improve energy efficiency, reduce overheating risks, and minimize power losses in low-voltage distribution systems.
