Abstract

Three-phase induction motors are key components in industrial power systems, but their performance is susceptible to internal disturbances such as stator resistance imbalance caused by aging, overheating, or manufacturing defects. This study aims to systematically analyze the impact of stator resistance imbalance on the efficiency and torque characteristics of squirrel cage rotor induction motors using equivalent circuit-based mathematical modeling. Unlike previous studies that used external resistors, this study modifies the stator resistance parameters directly in the model to represent more realistic internal degradation. Simulations were performed on a 3.73 kW, 400 V, 50 Hz motor with resistance imbalance variations from 0% to 20%. The results show that the imbalance causes uneven current distribution and an increase in stator copper losses of up to 5.94% at 20% conditions, although the percentage of current imbalance remains below 1%. As a result, the efficiency decreases linearly from 92.97% to 92.62%, while the mechanical torque experiences a small decrease from 95.88 Nm to 95.28 Nm. This phenomenon also has the potential to increase torque ripple and uneven heating. This study demonstrates that stator resistance imbalance, even small ones, has a significant impact on motor performance and lifespan, and therefore needs to be considered in predictive maintenance strategies and energy efficiency optimization.

Abstract

Rubber Tyred Gantry is one of the heavy equipment used at container ports to carry out container loading and unloading activities. One of the main components of the RTG is the spreader, which functions to lift and lower the container through a twistlock system at all four corners. However, in practice, technical problems often arise such as the failure of the twistlock lock, which has the potential to pose a risk of work accidents and equipment damage. This study discusses the interlock system on the RTG spreader as a safety and control system in the container lifting process. The analysis was carried out through experiments by observing the electro-mechanical working system on the spreader seen directly in the field and simulating the logic of the interlock using Zelio Soft 2. If the twislock does not fit perfectly into the twislock hole, then the landed light does not turn on and the interlock process cannot be carried out. The landed light is on, so the container lock process can be done by the operator by pressing the lock button on the master control in the operator's cabin.And the lock process is complete, then the container is ready to be lifted. The interlock system is effective in preventing twistlock locking if the spreader has not been landed and hoist lifting if the lock process is not complete. The implementation of this interlock increases safety and effectiveness in the loading and unloading process at the Port and also requires regular maintenance of the landed sensor (proximity) as well as the adjustment of the distance of the landed sensor to the twis tlock pin needs to be carefully adjusted to prevent detection failure. By implementing this system, the level of work safety and operational efficiency of RTG can be significantly improved.

Abstract

This study analyzes the pickup and slope settings of differential relays used for the protection of a 60 MVA power transformer at the Namorambe Substation. Differential relays play an important role in detecting internal faults in transformers by comparing the current entering and leaving the protected zone. Improper relay settings may lead to maloperation, reduced system reliability, or failure to isolate faults, which can disrupt power system stability. Therefore, accurate determination of pickup current and slope characteristics is essential to ensure reliable transformer protection performance. The research method used in this study is a quantitative analysis approach based on transformer operational data, current transformer (CT) ratios, nominal transformer capacity, and relay parameter calculations. The pickup setting was determined by calculating the minimum differential current required for relay operation, while the slope setting was analyzed to maintain relay stability during external faults and magnetizing inrush currents. Data analysis was carried out by comparing calculation results with standard relay protection principles and transformer operating conditions. The results show that the selected pickup and slope settings provide effective protection sensitivity while maintaining system stability under normal and fault conditions. The relay is capable of distinguishing internal faults from transient disturbances, thereby minimizing false trips and improving transformer operational reliability. The study concludes that proper differential relay coordination on the 60 MVA transformer at Namorambe Substation significantly enhances protection performance and contributes to the continuity and safety of electrical power distribution systems.

Abstract

Transformer load balancing is a mandatory maintenance activity that is regularly conducted to ensure the optimal performance of distribution systems. This activity serves as an essential effort to minimize neutral current, which contributes to power losses resulting from unbalanced loading conditions in distribution transformers. The load balancing process was carried out at Distribution Substation TP0067, with a capacity of 100 kVA, located within the operational area of ​​PT PLN (Persero) ULP Tanjung Pandan. The procedure commenced with load measurements on each feeder and phase, followed by detailed calculations of the phase load distribution. Based on the analysis results, the phases requiring load transfer to achieve balance were identified. Following the implementation of the load redistribution plan, it is expected that the neutral current will be significantly reduced, thereby reducing power losses and enhancing the overall efficiency and reliability of the distribution system.

Abstract

The reliability of an electrical protection system plays a highly crucial role in maintaining the continuity and stability of power distribution to consumers. One of the main factors determining this reliability is the performance of protection devices, particularly the Overcurrent Relay (OCR) and Ground Fault Relay (GFR). These relays act as the first line of defense in detecting and interrupting fault currents that occur within the electrical power system. Any inaccuracy in function, improper settings, or deviations in relay operating characteristics can lead to serious consequences, such as delays in fault clearing, expansion of the affected area, or even a complete failure of the protection system. This study aims to optimize the reliability of the protection system through functional and characteristic testing of the OCR and GFR installed at the Muara Teweh Substation, which operates under the jurisdiction of UP2D South and Central Kalimantan. The research methodology includes a series of tests on key parameters such as operating time, pickup current, time coordination between relays, and selectivity level in response to short-circuit and ground fault disturbances. The test data were analyzed to evaluate the conformity between actual performance and the predetermined relay settings. The results indicate that the relays at the Muara Teweh Substation are in good working condition and perform according to their expected characteristics. Recommendations for relay setting adjustments were also proposed to further improve protection system effectiveness. Through regular testing and proper calibration, the reliability of the protection system can be consistently maintained.

Abstract

The legal mechanism of bankruptcy relies on the concept of debt, because the absence of debt undermines the fundamental purpose of bankruptcy as a legal institution to liquidate the debtor's assets to satisfy creditors' claims. Debt is the main criterion that must be met in order to be able to apply for bankruptcy, along with additional provisions such as having two or more creditors, as stipulated in Article 2, paragraph (1) of Law Number 37 of 2004 concerning Bankruptcy and Suspension of Debt Payment Obligations (Bankruptcy Law). Notaries who have completed the bankruptcy process and are undergoing rehabilitation to improve their good name cannot re-apply to become Notaries. Here, the Notary will lose his/her right to work to carry out his/her position simply because the Notary has or has been sentenced to bankruptcy by the court. This bankruptcy is simply the notary's inability to pay the debt owed to the creditor, not a criminal act. If associated with the provisions contained in the 1945 Constitution of the Republic of Indonesia, namely Article 28 letter d concerning Human Rights which explains that everyone has the right to work and receive fair and proper compensation and treatment in employment relations, the efforts made in this problem are handled in accordance with the law and will be a substantial obligation for the curator. Based on Article 1 number 5 (Law Number 37 of 2004 concerning Bankruptcy and Suspension of Debt Payment Obligations), it states that a curator is an individual or an estate office appointed by the court to resolve and manage all problems of the bankrupt debtor's assets under the supervision of a supervising judge based on applicable laws. The citation of the law shows the clear jurisdiction of the curator over the debtor's property and assets.
