Abstract
Peningkatan kebutuhan beban yang bersifat induktif pada pelanggan TR (Tegangan Rendah) di atas 2,2kVA, maka dapat menyebabkan nilai faktor daya yang buruk dan hal ini akan membuat PT. PLN (Persero) mengalami kerugian akibat penggunaan daya nyata pada pelanggan TR berkurang. Dengan adanya permasalahan ini, maka perlu perhatian khusus agar nilai faktor daya yang terukur pada pelanggan TR sesuai dengan standart yang telah diterapkan oleh PLN.
Dalam tugas tugas akhir ini dibuat sebuah alat untuk mengukur nilai faktor daya dengan menggunakan 3 Voltmeter. Arus dan tegangan 3 Voltmeter diukur kemudian ditampilkan ke LCD 20x4 dan dikirim melalui media wifi untuk dilakukan monitoring secara jarak jauh. Perangkat ini juga dilengkapi media penyimpanan untuk menyimpan data hasil pengukuran guna mengaudit hasil kualitas listrik.
Alat pada Tugas Akhir ini dapat mengukur faktor daya dari beban yang diukur dengan metode 3 Voltmeter. Hasil dari alat ini mampu mengukur tegangan pada 3 Voltmeter dengan nilai kesalahan kurang dari 0,5% dan pengukuran arus mempunyai kesalahan kurang dari 1%. Hasil monitoring faktor daya juga diuji dengan menggunakan beberapa beban induktif dan resistif dengan faktor daya antara 0,83 sampai 0,98.
=====================================================================================================
Increasing inductive load requirements for TR (Low Voltage) customers below 2.2kVA,then it can cause a bad power factor value and this will make PT. PLN (Persero)suffered losses due to the use of real power in TR customers reduced. Given this problem, it necessary to pay special attention to the value of measured power factor on TR customers in accordance with the standard that has been applied by PLN.
In this final project will be made a tool measurement power factor by 3 Voltsmeter method. The measured 3 Voltmeter current and voltage are then displayed to the LCD 20x4 and transmitted over the wifi medium for remote monitoring. The device also features storage media for audit the results of power quality.
This tools in Final Project can measure the power factor of the load measured by 3 Voltsmeter method. The result of this prototype is capable of measuring voltage at 3 Voltmeter with error value less than 0.5% and current measurement has error less than 1%. Power factor monitoring results were also tested using some inductive loads resistive load with a power factor of between 0.83 and 0.98.
