Abstract

Photovoltaic as a renewable source of electrical energy is utilized at University of Bangka Belitung (UBB) as a source of additional electrical energy. With a capacity of 280 Wp per unit, the photovoltaic performance needs to be maintained so that their performance is getting better. After cleaning with cleaning fluid, the photovoltaic voltage output has increased from 13.7 - 16.8 volt to 17.4 - 22.6 volt. After cleaning the photovoltaic, the current output also increased from 0.33 - 1.8 A to 1.5 - 7.6 A. The real power generated also increased from 4.5 - 29.7 Watt to 26 - 164 Watt

Abstract

In the regulation of the general energy plan for the Bangka Belitung region, it is targeted that the total use of new and renewable energy will reach 17.21% in 2025 and 30.97% in 2050. This, of course, requires a measurable implementation to achieve this. In this regard, a photovoltaic design was carried out as a source of electrical energy in one of the government offices in Pangkalpinang. This office's daily demand for electrical energy is 78.79 kWh, with an average solar irradiance of 487.51 W/m2 and a measured ambient temperature of 26o – 33.3o C. The modeling is carried out using three types of photovoltaic panels, a namely polycrystalline, monocrystalline and thin film with a supply power is combined with a source from PLN and 100% photovoltaic

Abstract

Loading between phases must always be considered in order to reduce the imbalance, which results in an increase in neutral current and loss of conductor power. Non-linear loads can cause harmonics that affect the increase in copper losses in the transformer. Harmonics can cause distortion of the voltage and current waveforms, so attention must be paid to the specified limits so as not to interfere with the performance of electrical equipment. In addition, these parameters can affect the main electrical parameters, so they must be considered at the specified limits. This study aims to analyze the condition of load imbalance, harmonic content, and the effect on power loss in distribution transformers at Universitas Bangka Belitung. Parameters were measured using a Meterel Power Meter Analyzer type MI 2592 Power Q4 for ten days with the comparative method as a data analysis method. The average current unbalanced percentage is 9.91%, with the highest value at 24.31%. Energy due to power loss in the neutral conductor is 0.46 kWh/10 days, and the total conductor loss is 18.122 kWh/10 days.

Abstract

Bangka Belitung Island Province, which consists of 7 regencies/cities, has the potential for new renewable energy, both solar, wind, marine and biomass. Energy management policies in the regions have been outlined in regional regulations concerning the 2019-2050 regional general energy plan. It is targeted that in 2025, the energy mix will reach 17.21% and 30.97% in 2050. This article aims to highlight the potential and challenges on development and managing the renewable energy in Bangka Belitung Island Province.

Abstract

This study evaluates the performance of 20 kV circuit breakers by analyzing insulation resistance, contact resistance, contact synchronization, leakage current, and power loss. The insulation resistance analysis indicated that phases R and S did not show significant improvement after maintenance, with significance values of 0.065 and 0.166, respectively, while phase T exhibited a significant improvement with a significance value of 0.048. Contact resistance measurements revealed no statistically significant reductions after maintenance, with significance values of 0.209, 0.243, and 0.155 for phases R, S, and T, respectively. Additionally, contact synchronization in the open condition did not experience significant variations, whereas in the closed condition, all phases showed significant declines in synchronization after maintenance, with significance values of 0.003, 0.013, and 0.007. Leakage current analysis at a 20 kV phase-to-ground voltage showed that the highest recorded leakage current was 0.297 mA in the Eks Sumberejo feeder, significantly below the 20 mA threshold. Power loss calculations identified the highest power dissipation in the Depati Hamzah feeder at 69.87 W, with the lowest in the Eks Transmart feeder at 0.376 W. Energy loss assessment further showed the Depati Hamzah feeder experiencing the highest loss at 48.317 kWh, while the Eks Transmart feeder had the lowest at 0.278 kWh. These findings underscore the importance of routine monitoring and targeted maintenance to enhance circuit breaker reliability, optimize operational efficiency, and minimize energy losses in high-voltage electrical networks.
