Abstract

Kondisi ideal transformator tidak mengalami rugirugi,karena perbandingan kumparan merupakan perbandingantegangan dan secara praktek, daya masuk trafo tidak sama dengandaya keluaran, karena terjadi rugi-rugi inti besi dan kumparan.Transformator dapat dimodelkan dengan rangkaian ekivalen, nilaiparameter didapat dengan melakukan uji rangkaian tanpa beban danuji rangkaian hubung singkat. Drop tegangan parameter Rc dan Xmuji rangkaian tanpa beban sebesar 13,8 V.dan 17,2 V, dan uji hubungsingkat, diabaikan, karena tegangan yang terukur merupakantegangan di Zeq. Parameter L meningkat di uji hubung singkat, secarabertahap tegangan primer diturunkan dari 16 V , 14 V, 12 V, dengannilai L berturut-turut sebesar 4,9315 mH, 13,6148 mH dan 53,7771mH. Efesiensi dan regulation trafo turun akibat tegangan primerturun, terjadi perpotongan Efisiensi (4,6 kVA) dan regulation (4,5%)saat tegangan primer 195V. Pengujian tanpa beban, daya Poc dan Pscmenurun, tegangan primer 190V terjadi titik pertemuan dengan nila L= 0,0152 mH dan pengujian hubung singkat pada tegangan 14 Vdengan nilai L = 13,6148 mH

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.
