Abstrak

Perkembangan teknologi komputer dewasa ini mengalami kemajuan yang sangat pesat, dalam pengunaannya komputer dapat digunakan sebagai salah satu sarana monitoring pengukuran, seperti monitoring pengukuran tegangan dan arus listrik. Proses monitoring tidak selamanya harus dekat dengan objek pengukuran, dengan mengunakan jaringan nirkabel, proses monitoring dapat dilakukan jauh dari pusat pengolahan hasil pengukuran. Sistem dapat mengukur besarnya tegangan dan arus listrik secara nirkabel, hasil pengukuran tegangan dan arus listrik dapat dimonitoring secara realtime pada perangkat komputer mengunakan perangkat lunak LabVIEW sebagai interface penampil hasil pengukuran tegangan dan arus. Sensor yang digunakan yaitu sensor CT (Current Transformer) Sebagai sensor arus, Trafo tegangan sebagai sensor tegangan, Mikrokontroler Atmega 328p sebagai pemroses data dan KYL200U sebagai modul wireless transciever. Hasil pengukuran tegangan dan arus listrik dibandingkan dengan multitester digital dari hasil pengujian yaitu mempunyai rata – rata persen error sebesar 0.82% untuk pengukuran tegangan, pengukuran arus beban resistif 7.8%, beban induktif 6.4% , dan beban kapasitif 9.34%. Sedangkan untuk hasil pengujian jarak maksimum modul KYL200U saling berkomunikasi dengan pengaturan default (baudrate 9600bps, frekuensi 433MHz) secara tidak line of sight sejauh ±126 meter, dan secara line of sight sejauh ±465 meter. Kata kunci : Tegangan, Arus, KYL200U, Current Transformer, Monitoring, LabVIEW Abstrak Bahasa Inggris Technology of computers development progressed very fast, The function of the computer is to measurement monitoring, like monitoring the measurement of voltage and current electricity. The process of monitoring not always near to the object, with using wireless networks , the process of monitoring can be solve far from the center of processing result. The system can measure the voltage and electrical current wirelessly, The result of measuring voltage and an electric current can show in real time on computers use software interface LABVIEW as a result viewer of measuring voltage and current. The sensor that using was CT sensor (Current Transformers) as a current sensor , voltage transformer as voltage sensors , microcontroller atmega 328p as data processor and KYL200U as a wireless transceiver module. The results of the measurement of voltage and current of electricity compared with digital multimeter has a results of testing which average percent error of 0.82 % to the measurement of voltage, the measurement of the current load resistive 7.8 % , Inductive load 6.4 %, and capacitive load 9.34 %. Then the testing of maximum distance module KYL200U communicate with the default settings (baudrate 9600bps, frequency 433mhz) not in a line of sight as far as ±126 meters, and in line of sight as far as ±465 meters. Key Word: Voltage, Current, KYL200U, Current Transformer, Monitoring, LABVIEW
