Abstract

Hasdone research Michelson interferometer system along with data acquisition, which is used for measuring strain in the tensile testing machine. Moveable mirror Michelson interferometer system mounted on the specimen clamp tensile testing machine. When the load is given in the test specimen, the specimen having the length and cause of any difference wave length of the laser beam. The wave length differences cause interference, and produce an interference pattern in the form of dark-light pattern (fringe). Interference pattern will be detected phototransistor sensor signal wave form, then recorded and processed by electronic circuits and interface microcontroller circuit, as well as converted and displayed as a displacement/increase in length (strain) of the test specimen. The experimental results obtained by the Michelson interferometer system that measures the movement (displacement) of the best maximum 9 mm. Displacement measurements using aluminium specimens produced a mean standard deviation of 0.023 (0.2%) and 0.074 (0.08%), and use of low carbon steel specimen rods produce a mean deviation of 0.08 (0.72%). appears that the system is very close to the measurement interferometer with ekstensometer. Measurement accuracy at the time of the test specimen is attached to be reduced compared to the measurements on the crosshead without load, due to a growing vibration machine.

Abstract

ABSTRAKDalam pengembangan generator tiga fasa magnet permanen diperlukan pengukuran besaran-besaran untuk melihat karakteristik generator. Besaran yang biasanya diukur adalah tegangan, arus, dan daya, namun bentuk gelombang keluaran tegangan dan arus tiap fasa kurang diperhatikan apakah sinus atau tidak. Maka perlu dirancang sebuah sistem yang bisa menampilkan bentuk gelombang tegangan dan arus sekaligus. Sistem ini diimplementasikan menggunakan sensor tegangan, sensor arus, rangkaian pengondisi sinyal, Arduino Due, dan komputer sebagai penampil menggunakan bahasa Python. Hasil pengujian diperoleh bahwa sistem bisa menampilkan bentuk gelombang keluaran tegangan dan arus, menampilkan nilai maksimum, minimum, rerata, dan rms. Nilai galat rata-rata untuk ketiga pengukuran tegangan adalah 1%, dan untuk pengukuran arus adalah 3,15%.Kata kunci: gelombang tegangan dan arus, Arduino Due, Python, tiga fasa ABSTRACTThe development of three phase permanent magnet generators require the measurement of related quantities to determine the characteristics of generator. The common measured quantities are voltage, current, and power. However the voltage and current output waveforms of each phase are not considered. Therefore a system is designed which is able to display voltage and current waveforms at once. This system is implemented using a voltage sensor, current sensor, signal conditioning circuit, Arduino Due, and a computer as a GUI using the Python programming language. The results of implementation and testing show that the GUI is able to display the voltage and current output waveforms, in addition, performs the maximum, minimum, average, and rms values. The average error value for the three voltage measurements is 1%, and for the three current measurements is 3.15%.Keywords: voltage and current waveforms, Arduino Due, Python, three phases
