Abstract

This research is motivated by the observation that several industries still use manual control circuits, such as star delta controllers on 3-phase motors. So the author will conduct a study on the effect of using a star delta system with a manual circuit and PLC on a 3-phase electric motor with a capacity of 7.5 kW. The purpose of this study is to determine the stability of the initial current of the electric motor in the starting process, the current between the PLC and manual circuits and also to determine the occurrence of overshoot. PLC makes it easier to operate if the hardware and control room are 20 m apart, namely by using HMI (Human Machine Interface) to monitor the circuit. The data collection method is by observing the star delta PLC and manual circuits on 3-phase electric motors. The results of this study are that the star delta PLC control circuit produces a stable starting current surge of 21.11 - 22.37 A. Meanwhile, the manual star delta system has a starting current surge of 22.01 - 23.53 A. The current value on the star side measurement between the PLC and manual is 4 amperes - 5 amperes, while the star current value is calculated at 4.75 A without load. At the delta value produces a larger current because it uses a line-to-line voltage of 8.24 A without load. In the use of the circuit between PLC and manual there is no overshoot or voltage drop.

Abstract

Covid is currently starting to subside, one of which is with the handling, recommendation for vaccines from dose 1 dose 2 and booster vaccines. Handling and recommendation for vaccines is one form of government policy and is one of the government's responsibility efforts to the community. The use of disinfectants can be one solution for the community to start living a healthy and clean life, but many people are reluctant to bring disinfectants to public places. The existence of a prototype of an automatic disinfectant tool can provide a solution for people who are reluctant to bring disinfectants out of the house, even every community house can make an automatic disinfectant tool for indoor use. Based on the results and discussions above, it can be concluded that the design of the prototype of an automatic disinfectant sprayer with a proximity sensor based on the internet of things (IOT) to support healthy living habits after the pandemic has been successfully carried out. While the results of the efficiency of the proximity sensor detection time against objects were 86.3% with a proximity sensor error value of 2.1%. The prototype of an automatic disinfectant sprayer with a proximity sensor based on the internet of things (IOT) has successfully sent the results of the prototype disinfectant usage counter to the telegram. Although there are still many shortcomings in this study in building a prototype of an automatic disinfectant sprayer with a proximity sensor based on the internet of things (IOT), the overall system that was built can run well..

Abstract

The existence of batteries in the substation functions to maintain the stability and reliability of the DC electrical system, where the protection system on the control panel must not go out. Therefore, routine battery maintenance and testing are needed so that the battery can run properly and optimally. Battery testing is a routine agenda that is carried out every 6 months. For daily maintenance, a visual inspection (vision) can be carried out, while monthly maintenance is carried out in the form of a battery equalizing test which is carried out so that the 110V DC battery remains stable and can supply DC to auxiliary equipment when in an emergency. The test results obtained in this study were that the equalizing test on the 110V DC battery that was carried out obtained the battery results in normal conditions. This is explained, when the battery is connected to the load and the voltage per battery cell is measured in floating charging mode showing an average voltage of 1.34 V DC. When the battery is in equalizing charging mode, the voltage capacity on each battery cell can be said to be normal or stable with a total voltage value of 128.2 V DC and a temperature value of 27 ºC. For the measurement results of each battery cell after equalizing charging, the average voltage value per battery cell is 1.35 V DC with a total voltage of 116 V DC. It can be concluded that the equalizing test on the 110V battery unit 1 of the 150 KV Main Substation is fairly normal and the battery is ready when run in discharge mode

Abstract

Increasing consumers of electrical energy impacts increasing the risk of disruption that distribution systems can expose to consumers. In order not to interfere with the distribution of electrical energy, the protection system installed in the electrical energy distribution network must work optimally. Coordination between protections installed in the distribution network has a significant impact on the quality of distribution. Therefore, the protection components, that is, the reclosing switch, the overcurrent relay (OCR), and the ground fault relay (GFR) must be configured correctly. Proper adjustment is where the protection system works according to its capacity, so the effects of disturbances can be minimized, the disturbances are not widespread and can lead to power outages. The grid protection system from the Lomanis –05 feeder line to ULPSidareja is already good because the components of the protection system are well matched. Since the components do not comply with SPLN 64: 1985 and IEC 60255, that is, 0.35 to 0.4 seconds, we can conclude that the quality of coordination between protection systems is good, but we still evaluate the applied settings. is needed. Not compliant with SPLN 64: 1985, but compliant with IEC60255.

Abstract

Electrical energy is a very essential energy where almost all human needs are related to it. The distribution of electricity in both of transmission and distribution networks are expected to operate optimally and continuously. The constraints in the distribution of electrical energy are usually caused by several factors, including rainfall and load imbalances. The data on the value of rainfall and load imbalance will later be analyzed with the value of electrical power loss. This study aims to determine whether rainfall and load imbalance affect the electrical power loss. By knowing the value of these constraints, it will be analyzed with the value of electrical power loss. The type of research used is quantitative analysis research using multiple linear regression test.. Based on the results of linear regression analysis in the summary model, ANOVA, the coefficient showed a rainfall significance value of less than 0.05, it meant that there was no significant effect on electrical power loss and a load imbalance significance value of more than 0.05, mit showed that there was a significant effect on power loss electricity. Meanwhile, the percentage of influence of the independent variable of rainfall and load imbalance on the dependent variable of power loss was 9,4% and the remaining 90,6% was influenced by other variables not examined.
