Abstract

The component that is often used in practice is the relay. However, in practice, students often have problems when using relay components due to damaged relays. This happens because there is no tool to detect a damaged relay quickly. To overcome these problems, a microcontroller-based relay tester was made that can quickly check the feasibility of the relay. Which aims to detect a damaged relay quickly. Where the measurement process is by connecting the relay to the available socket, then the output on the relay will be processed by Arduino and the results will be displayed on the LCD and LED. The output on the relay is OK if it's still functioning and Error if it's damaged and the LED is for displaying the test light, if one of the lights goes out, it means the relay is an error, and if there's no damage, the lights will all turn on. From the results of testing more than 10 times testing the tool, it was found that the tool functions well and is accurate. Comparison data was also obtained when testing relays using a relay tester that was made, the time when checking only needed 01.18 seconds for every 1 relay. And for the 10x experiment of relay testing using a relay tester, alternating between 5-foot, 8-foot and 11-foot relays only takes 13.2 seconds.

Abstract

Power factor is used to determine the quality of electric power. The factor has a parameter of 0-1 where the number 1 can be said to be close to perfect power factor while close to 0 can be said to be less good. power can also be affected by load. With the improvement of the power factor close to 1, the power energy will work optimally. A 3 phase induction motor is an inductive load that requires reactive power. If reactive power cannot be controlled, it will cause low power factor. The study uses a 3 phase slip ring motor as a load, a capacitor bank panel with Arduino mega 2560 control as a power factor improvement, with a value of step 1 = 5 F, step 2 = 10 F and step 3 = 15 F. The power factor of the slip ring motor at a load of 0 Nm before repair is 0.24 with a reactive power of 1106.15 Var. After the capacitor is activated automatically in Step 5, step 1 and 3, the power factor increases to 0.97 with a reactive power of 259.63 Var. The results of the power experiment at 0 Nm load with a power factor improvement of 0.97, the reactive power and current tend to decrease as the power factor value increases, thus making electrical energy more efficient and optimal.
