Abstract

An age data of the same type cables under the same operation condition in a regional transmission system was collected. Use a probability analysis method and the age data to calculate the reliability functions of normal distribution and Weibull distribution, which reflect the reliability level of cables. Effect Analysis system Failed mode (EAFM) is applied to find the characteristic fault parameters, which contribute to the cable failure and can be obtained by the preventive tests. Fuzzy membership function is constructed to estimate the failure probability. Fuzzy analytic hierarchy process (AHP) is employed to define the importance weight of failure mode, and the reliability value of the cable will be gained through the weighted average method. It is estimated by using the reliability function and the cable reliability value that the expected damage cost (EDC) of the transmission system is caused by cable failure. The interest income can be gained by delaying the retirement of the aging cable. Finally, an appropriate time of the cable retirement is found when making an economic comparison between the EDA and the interest income due to the retirement delay.

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

Electricity theft is an activity that is detrimental to the state where PLN as the party that distributes electricity has unknowingly lost its main commodity without any reciprocity in the form of payment. To overcome electricity theft, Execution of Electricity Use (P2TL) is carried out. Implementation of Electric Power Use (P2TL) is an activity to control electricity users who do not comply with installation standards. P2TL activities include planning, inspection, technical and/or legal actions and settlements carried out by PLN on PLN installations and/or Electric Power User installations. P2TL activities carried out in the Koba area from October to December 2023 found 3 violations in the area. The kWh saved as a result of P2TL from October to December was 21,480 kWh. From the kWh savings obtained, the highest loss was in October of 0.47% and the loss obtained without P2TL kWh savings was 0.48%. So that the kWh savings obtained from P2TL can reduce Non-Technical Losses. The more P2TL violations are found, the higher the reduction in losses obtained by PT PLN (Persero) ULP Koba.

Abstract

Power Supply Current Limiter CircuitThe current limiter to be analyzed works to create an overcurrent protection system and is able to work quickly, when overcurrent occurs due to overload or short circuit. The current limiter circuit uses two transistors configured as a differential pair, combined with a fixed current source to limit the current available to the pass transistor of the voltage regulator. From the research results, it was obtained that the measurement results of the current limiter had been successfully made, namely for a 5 VDC load with a limit of 0.30 A and a 12 VDC load with a limit of 0.7 A. In normal condition testing with a resistor value of more than 16 Ω for a 0.30 A current limiter and a resistor value of more than 20 Ω for a current limiter with a limit of 0.7 A, the output current of the current limiter has a value based on the resistor load value (Ω), namely the greater the resistor value, the smaller the current will be for a 0.30 A current limiter and for a 0.7 A current limiter. In overcurrent condition testing with a resistor load value smaller than the resistor load under normal conditions, namely less than 18 Ω for a 5 VDC current limiter with a limit of 0.30 A and less than 20 Ω for a 12 VDC current limiter with a limit of 0.7 A, the output current of the current limiter for a 5 VDC load. The output current of the current limiter is in accordance with the current limit in the circuit according to the ability of the synchronous buck converter and the battery and the devices connected to it to withstand the current. In short circuit condition testing, the current limit value is in accordance with the designed limit, namely 0.22A and 0.45A.
