In the research, analysis of the over current relay protection settings on the 30 MW generator at the Poso 1 PT PLTA unit. Poso Energy obtained that the maximum load current data on the generator was 2042 A, while the calculation results obtained were 2041.7 A. For the relay (top) operating time in the specification data, the value was 1.4 s, while in the calculation results it was 1.3 s. And for the setting current (Is) in the specification data the value is 4.7 A, whereas in the calculation results it is 4.28 A. Over current relay (OCR) or over current relay is an auxiliary relay from the differential relay, the over current relay is used to secure the generator of the overcurrent in the Poso 1 PLTA is PCS-985GE-EN-H2-110V-5A. In the specification data, the TMS value is 0.15 s, while in the calculation results it is 0.14 s. This means that data in the field is slower to protect components from interference by 0.01 s. However, overall the overcurrent relay settings on the generator at the Poso 1 PLTA are still in good condition.","PeriodicalId":512591,"journal":{"name":"Foristek","volume":"59 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141106100","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the Undergraduate Department of Electrical Engineering, Faculty of Engineering, Tadulako University, the robotics course is a mandatory subject studied by students, especially students who take the weak current concentration (TEN). This research aims to provide students with an understanding of how to control a robot arm. The design of a robot arm system with 4 degrees of freedom is made using several types of control such as control using Arduino IDE software, push buttons and potentiometers. The results of testing the robot arm trainer after controlling it with three types of control were successful. In the first control using the Arduino IDE software control it shows that the direction of rotation of the motor rotates according to the program target given, in the second control using a push button it shows that the speed and acceleration are directly proportional to changes in motor degrees, then in the third control using a potentiometer it shows that the degree mapping on the potentiometer is directly proportional to the degree of the stepper motor. However, in the test there were differences in degree values when the motor rotated which caused the resulting data to be inaccurate. This is due to a mismatch in tooth size between the belt and the stepper motor gear, causing wear on the belt.","PeriodicalId":512591,"journal":{"name":"Foristek","volume":"55 30","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141103016","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The neodymium magnet used in the buoy functions as a trigger to activate the reed switch when the buoy height reaches a certain level. The use of the voltage divider principle is to obtain variations in the sensor output voltage which is then converted into water level readings. The process of monitoring waste liquid levels uses LabVIEW software. \u0000Research has been tested in one of the departments in the metal processing industrial area which obtained the results that the sensor readings correctly provide an output signal to the microcontroller which functions as a relay controller which activates the drain pump motor when it reaches full level.

Along with the rapid demand for electricity in Indonesia. The reliability of the electric power system is key to meeting the community's needs for electrical energy. This is due to the increasing number of human activities that require electrical energy. \u0000This study aims to analyze the reliability of protection coordination, working principles, security, and SBEF relay simulation when a fault occurs at the Maros substation. The method of data collection and direct observation in the field was carried out precisely at the Maros 150 kV Substation, the Maros Transmission and Substation Service Unit (ULTG). \u0000The results of the study, namely the reliability of the SBEF relay protection coordination when a fault occurs at the Maros substation, show that the first relay to work is the OCR GFR on the feeder side because, based on the working current settings and working time, if given a fault current of 3021 A, it will work after 426 ms, followed by the incoming side GFR OCR relay, SBEF stage 1 Fault percentage = 0075% so that it has a reliability percentage of 100%. The working principle and safeguards carried out on the SBEF relay when a fault occurs at the Maros substation and the data recap of the Maros ULTG fault can be seen by comparing the frequency of faults that cause the transformer to go out before and after the implementation of the two-stage SBEF relay function and the frequency of faults that cause the transformer to go out at ULTG Maros in 2019 as many as 1times and in 2020 as many as 0 times.
