Abstract

A static electrical device is like a power transformer, one of the functions of which is to transfer one power circuit to another circuit, either changing the voltage without having to change the frequency. This paper described a Protection is a system in electricity and has a function as an isolate, breaker and separator if there is a disturbance. The working principle of the differential relay is to compare the vector I1 of the primary side current with I2 of the secondary side current. "The results of the mathematical calculation of the setting current for the differential current obtained are 0.0961865394 A and this is different from the setting current installed in the differential relay on the power transformer of 1 substation, namely 0.3 A."

Abstract

With the development of technology, there are some basic things that must be known and learned about airplanes, one of which is the exterior lighting system where the functions and uses vary. Exterior lighting plays an important role in airplanes on land and in the air and is a basic thing in knowing this exterior lighting system such as the layout, color and function of the lighting. For this reason, research and the creation of exterior lighting indicators on airplanes based on Arduino Atmega 2560 were conducted. In the research and creation of this tool, the main input from this tool is an adapter that produces a voltage of 5 V. Then there are 8 toggle switches that function as switches for each LED. In general, when the toggle switch is in the ON condition, the current and voltage have been sent to the system as a whole. Then the Arduino Atmega 2560 will process the inputted data. Furthermore, the Arduino Atmega 2560 sends the processed data to each LED so that the LED can light up according to its function and use. For the information generated such as each LED is on or not can be seen on the LCD. The results of functional testing show that the design is able to carry out the function of each LED. The design has a flash rate of beacon light of 45 times per minute and a flash rate of strobe light of 60 times per minute. Taxi light, Logo light, Landing light, Navigation light, Takeoff light, Runway light and Wing light do not have a flash rate or are steady. There is a time difference or delay between the wings strobe light and the tail strobe light of 1 second. The indicator can display information if there is damage to the LED.

Abstract

An electric wheelchairs are vital mobility aids for individuals with mobility impairments or special needs. These wheelchairs rely on electric motors powered by batteries to provide the necessary propulsion. The accuracy and reliability of battery power measurement in electric wheelchairs are crucial for maintaining balance, stability, and ensuring a safe and comfortable user experience. One critical component in electric wheelchairs is the load cell, which measures the applied load such as user weight or additional loads. Over time, load cells may experience changes in their characteristics, such as sensitivity alterations or drift, potentially affecting load measurement accuracy. Therefore, calibration of load cell loads in electric wheelchairs becomes essential. Calibration ensures that load measurements remain accurate and consistent over time by comparing the output produced by the load cell with accurately known loads, and then adjusting the scale or resetting load cell parameters to achieve accurate measurements. This research aims to analyze the impact of load cell calibration on the performance of electric wheelchair batteries. The research questions include evaluating the effects of calibration on load measurement accuracy, identifying factors influencing load cell performance, and developing effective calibration methods. The study focuses on assessing how load cell calibration influences the performance of electric wheelchairs, with particular attention to measurement accuracy and stability aspects. The objective of this research is to enhance load measurement accuracy in electric wheelchairs through proper load cell calibration. The benefits include improving safety and comfort for wheelchair users by providing accurate load measurements, ensuring wheelchair balance and stability, and reducing the risk of injury or failure. Additionally, the findings contribute to the development of better electric wheelchair technology and enhance the quality of life for users.

Abstract

Single-mode optical fibers are widely used in modern communication systems due to their high data transmission capacity and low signal attenuation. However, the physical condition of the optical fiber, such as bending caused by mechanical pressure, can affect transmission performance. This research aims to analyze the effect of pressurized bending on single-mode optical fibers and its impact on the attenuation of transmitted light intensity. Experiments were conducted by varying the bending radius and pressure applied to the optical fiber to measure changes in the received light intensity. The results show that as the bending radius decreases and the applied pressure increases, the attenuation of light intensity increases significantly. The reduction in light intensity occurs due to the leakage of light modes from the fiber core as a result of physical deformation in the fiber structure. These findings are important for designing more efficient and resilient optical fiber installations, especially in environments prone to physical pressure and bending.

Abstract

The use of Uninterruptible Power Supply (UPS) plays a crucial role in maintaining power stability, especially in ICONNET network transmission stations, which require a reliable and uninterrupted power supply. UPS functions as a backup power source that prevents sudden power disruptions, reducing the risk of equipment damage and service interruptions in telecommunication networks. This study aims to analysed the impact of UPS usage on power consumption at ICONNET transmission stations. The research methodology includes measuring power consumption before and after UPS implementation, analysing power efficiency, and evaluating the impact of UPS on system reliability. Data were collected through monitoring electrical load, UPS operation duration, and power performance during grid outages. The results indicate that UPS usage can optimize power consumption efficiency by stabilizing voltage and frequency. Additionally, UPS contributes to enhancing the operational reliability of transmission stations by preventing downtime caused by power failures from the main grid. However, UPS efficiency is highly influenced by battery capacity, power conversion efficiency, and the electrical load characteristics of the transmission station. Thus, this study provides insights for network operators in selecting and managing appropriate UPS systems to improve energy efficiency and transmission system reliability.

Abstract

Solar Power Plants (PLTS) are an efficient renewable energy solution for providing electricity, especially in areas not covered by conventional power grids. This study aims to analyze the PLTS system as a power supply for submersible water pumps, focusing on energy efficiency, voltage stability, and system reliability under various operating conditions. The research methodology includes experimental analysis and simulation using a quantitative approach. Data were obtained through direct measurements on a PLTS system consisting of solar panels, a power controller, batteries, and an inverter as the power source for the submersible water pump. The analyzed variables include solar panel output power, battery charging efficiency, and pump performance under different weather conditions and workload scenarios. The results showed that the PLTS system could provide sufficient power to operate the submersible water pump with an average efficiency of XX%. The voltage stability generated by the inverter remained within the appropriate range for pump operation, with minimal fluctuations under maximum load conditions. However, reduced sunlight intensity during cloudy and rainy conditions led to decreased power output, affecting pump performance. To enhance system reliability, it is recommended to use batteries with larger capacity and a smart control system for optimized power distribution. In conclusion, the PLTS system can serve as an effective and environmentally friendly power source for submersible water pumps. However, further optimization is needed to ensure stable performance under various weather conditions.
