Abstract

The availability of electrical energy is an important thing needed in everylife. To control if there is a power failure happened from the main supply (PLN) a device is needed, so that the reliability of the transmission system is maintained. This tool is known as the transfer switch the cam switch. When there is a disruption to the PLN electricity then the cam switch will automatically be moved to the generator supply, if the PLN electricity has improved then the cam switch is again moved to the PLN contact, and to move the cam switch is used an electric motor. In this research designed a stepper variable reluctance motor as a cam switch driver. Stepper variable reluctance motors are designed using magnet infolytica software with a combination of 6 stator poles and 4 rotor gears. The reluctance 6/4 stepper variable motor is expected to be able to drive the cam switch with a torque of 0.3 Nm and a 30-degree rotor step length. After being analyzed, it was obtained that the optimal dimension values with outer dimension of the stator 122 mm, inner diameter of the stator 72 mm, outer diameter of the rotor 71 mm and the machine length is 44.5 mm with 800 turns. The results of the analysis of the research obtained a machine torque value of 0.192 Nm. When the length of the machine is enlarged to 70 mm then the machine torque is 0.301 Nm, but the large flux density is 1.41 Tesla to 1.64 Tesla.Keywords : stepper variable reluctance motor, cam switch, software magnet infolytica

Abstract

Pada instalasi listrik, saklar pemindah berfungsi untuk memindahkan pasokan tenaga listrik dari jaringan utilitas (jaringan listrik PLN) ke sumber tenaga listrik cadangan seperti genset ketika pasokan tenaga listrik dari jaringan utilitas terputus. Saklar pemindah akan kembali ke posisi normalnya apabila pasokan tenaga listrik dari jaringan utilitas telah kembali pulih. Artikel ini memaparkan rancang bangun suatu saklar yang digerakkan oleh cam atau cam operatedswitch untuk digunakan sebagai saklar pemindah.Saklar pemindah mempunyai 3 posisi, posisi 0 atau posisi netral digunakan untuk membuka hubungan beban listrik dari jaringan listrik PLN dan dari genset, posisi I digunakan untuk menghubungkan beban listrik ke jaringan listrik PLN dan posisi II digunakan untuk menghubungkan beban listrik ke genset. Sudut kerja cam adalah ±30 derajat. Posisi I dicapai dengan menggerakkan cam 30 derajat berlawanan arah jarum jam dan posisi 0. Posisi II dicapai dengan menggerakkan cam 30 derajat searah jarum jam dari posisi 0. Limit switch digunakan sebagai saklar yang nantinya akan disentuh oleh cam. Apabila limit switch disentuh oleh cam, maka kontak dari limit switch akan menutup dan apabila cam tidak menyentuh limit switch, maka kontak limit switch akan terbuka.Cam nantinya akan digerakkan oleh motor stepping variable reluctance dengan panjang langkah 30 derajat.

Abstract

This paper presents an attempt to design and make a rogowski coil together with its signal conditioning circuit for alternating current measurement. The induced voltage between rogowski coil ends is connected to active integrator circuit to yield voltage signal that is linear corresponding with the measured current. The output of integrator circuit is amplified its level before rectified using precision rectifier circuit. The output of precision rectifier is filtered using capacitor before connected to analog input port of ATMEGA8535 microcontroller. Microcontroller performs data acquisition of the signal, processes it and sends information of the rms value of the measured current to an LCD display. A test with 0.5 class moving-iron type amperemeter as a comparison shows that for measurement of alternating current from 0 to 5 amperes, the maximum value of error measurement is 2.5%.Keywords: rogowski coil, active integrator, precision rectifier, ATMEGA8535 microcontroller
