Abstract

The development of the electric power system is quite rapid in Indonesia, where the development of the electric power system will not experience a decline and will continue to increase. To distribute electrical energy to consumers, transformers are the main component in the electrical system. During its operation, transformers often experience faults, making reliable protection and security systems necessary to maintain the smooth operation of the system. Protection systems are designed to interrupt faulty currents and protect equipment from damage caused by these currents. One of the primary protection devices for transformers is the differential relay, which operates quickly without requiring coordination with other relays. Differential relays work based on the vector difference between two or more electrical quantities exceeding a predetermined threshold. In this study, a Siemens 7UT5121 protection relay was used. To facilitate testing and fault analysis in the settings of this protection relay, simulations were conducted using ETAP software. The protection relay settings were configured to safeguard the transformer if there was a current difference between the CT on the primary and secondary sides within the protection zone. Based on calculations, the CT ratio for nominal current (I₁) was found to be 230.94 A, and the nominal current (I₂) was 1905.25 A. The CT secondary currents were calculated as 0.769 A for I₁ and 0.866 A for I₂. In the differential relay, the differential current was recorded at 0.097 A, while the restrain current was 0.817 A. The slope percentage analysis yielded values of 11.18% for slope 1 and 23.74% for slope 2. The differential current setting value obtained was 0.379 A. The relay will not operate if a fault occurs outside the protection zone, ensuring the reliability of the transformer protection system

Abstract

Managing 24-hour electrical energy consumption in healthcare facilities requires efficiency without compromising service quality. This community service initiative, conducted in collaboration with the Dr. Efram Harsana Air Force Hospital (RSAU) at Iswahjudi Air Force Base, aimed to assess energy usage and formulate efficiency recommendations for the Emergency Department (IGD) and the Jupiter and Mars Pavilions. Activities included site observations, interviews, electrical system identification, and the measurement of electrical and environmental parameters—using tools such as power quality analyzers, lux meters, thermohygrometers, clamp meters, and thermal cameras—followed by data processing, Energy Intensity (IKE) calculations, and the presentation of recommendations to the partner. Results indicated installed loads of 10,359.5 W for the IGD, 16,664 W for the Jupiter Pavilion, and 14,713.5 W for the Mars Pavilion. Findings included a power factor of 0.469 for the Jupiter Pavilion, current imbalances of 66.8% (IGD) and 27.1% (Jupiter Pavilion), and a Total Harmonic Distortion of Current (THDI) of 15.62% for the Mars Pavilion. Several rooms failed to meet lighting and thermal comfort standards. Recommendations focused on load balancing, evaluating reactive power compensation, monitoring harmonics, optimizing lighting and air conditioning systems, installing metering instruments, and implementing periodic maintenance to support the partner's energy management.

Abstract

Dadapan Village, specifically Ngrancang Hamlet, is an agricultural area where most farm access roads lack adequate public street lighting. This condition hinders farmers' activities during the night and early morning such as irrigation, fertilization, and crop distribution and poses safety risks. This community service initiative aims to transfer solar-powered street lighting technology to the Ngudi Rahayu Farmer Group to enhance road safety and foster village energy self-sufficiency. The implementation process comprises five stages socialization, training, technology deployment, mentoring and evaluation, and program sustainability carried out collaboratively by lecturers, students, and farmer group members. The technology deployed involves installing two solar-powered street lighting units integrating monocrystalline solar panels, lithium batteries, LED lights, and automatic light sensors along a 300-meter stretch of farm access road. The results indicate that both units are successfully installed and fully functional, automatically illuminating for 10–12 hours without reliance on the national grid (PLN). The installation of these lights enhances safety and convenience for farmers, facilitates crop distribution, and improves the partners' understanding of renewable energy solutions that are self-sufficient, cost-effective, and environmentally friendly.
