Abstract

The electric power system must be able to provide a continuous supply of electrical energy with a standard amount of voltage and frequency in accordance with applicable regulations and the system must immediately return to normal conditions if the system experiences a disturbance. This tool is used to detect faults and the location of the fuse cut out (FCO). PZEM-004T sensor to read the voltage of each phase. Neo-6M GPS to get the coordinates of the location which is accessed via Google Map, then the Telegram bot sends a message to the feeder status information, the location connected to the Google Map, the transformer address and the voltage value after the disturbance. The average difference between the actual location distance to the location recorded by GPS NEO-6M is 4.10 meters and recorded by GPS Coordinates is 6.90 meters. The average percentage error of voltage values for each phase in the measuring instrument and in the sensor is in the R = 0.62 % phase, S = 8.94 % and T = 8.57 %. The Telegram bot sends a message when the FCO in the S phase is decided, namely the S Phase status is Lost, because the voltage in the S phase decreases from 221.9 V AC to 117.7 V AC, with the average duration of sending Telegram bot messages is 41.3 seconds.

Abstract

Electrical energy is one of the most important human needs and cannot be separated from daily needs. Lack of electrical energy can interfere with human activities as well. Therefore, the availability of electrical energy must be maintained. In Indonesia, the need for electrical energy is increasing because it is seen from population growth and advances in information and technology. The use of electric power is usually more widely used in the study rooms at the Bengkalis State Polytechnic, especially the Electrical Engineering Department consisting of classrooms, and laboratories and electrical workshops. In this study room, the electrical installation system is still conventional to turn on the lights, air conditioning and laboratory equipment centered on the panels in each room. Problems arise when room users do not turn off electrical equipment after the lecture is over and leave the room. The wasted use of electrical energy in the study room can be minimized by updating the conventional control system to semi-automatic. The system applied is smart door and smart class is an access to the electrical system by attaching the RFID card of lecturers who enter the class to the RFID access control. The test results show thatRFID access control detects RFID cards up to a distance of 6 cm. The exit button uses a low activation system where when pressed the output voltage is 1.10 volts and when released the output voltage is 17.41 volts. The electric bolt lock terminal voltage when active is 0 volts and when not active is 14.18 volts. The activation time of the RFID reader switch is 1.08 seconds and the deactivation time is 29.51 seconds. The system can work with a 100% success rate and an average execution time of 2.27 seconds.
