Abstract
Kegagalan peralatan pengaman arus listrik mendeteksi gangguan pada instalasi listrik tegangan rendah menjadi penyebab utama kebakaran akibat gangguan listrik. Gangguan listrik yang gagal dideteksi oleh peralatan pengaman adalah busur api listrik yang muncul saat terjadi hubung singkat. Besar arus yang cukup untuk membuat bunga api dan cepatnya durasi gangguan menjadi penyebab kebakaran dan kegagalan deteksi dari peralatan pengaman. Pada penelitian kali ini akan dilakukan pendeteksian arcing berbasis smart-phone pada tegangan rendah dan Analisa impedansi jaringan terhadap kinerja peralatan deteksi. Metode pendeteksian dilakukan dengan mikrokontroler yang berfungsi sebagai sensor dan pengirim data. Mikrokontroler mendeteksi adanya gangguan dengan cara mengambil sampling arus dan di transformasikan dengan menggunakan metode wavelete transform diskrit yang akan memberikan keluaran sinyal high frequency dan digunakan untuk menganalisa sinyal gangguan. Metode pengambilan data dibedakan menjadi 3 kondisi agar alat pendeteksi dapat membedakan gangguan, yaitu kondisi normal, switching, dan arcing. Serta membandingkan tiga karakteristik kondisi tersebut dengan perbedaan daya beban dan panjang imp edansi saluran. Pada penelitian ini didapatkan hasil yaitu peralatan yang mampu mendeteksi arcing berbasis smart-phone dan tidak berpengaruhnya variasi impedansi saluran terhadap kinerja pendeteksian alat.============= The failure of current protection equipment to detecting electrical fault at low voltage installation became the main cause of fire disaster. Electrical fault that failed to be detected by the protection equipment was an electric arc that appears when a short circuit fault occured. The magnitude of current that sufficient to make sparks and the rapid duration of the fault caused the fire and the failure of the protection equipment to detecting the fault. In this research, smart phone would be used to detecting arcing in low voltage equipment and analysi s the influence of impedance against the performance of protection equipment. Microcontroller would be used as detection method that functionate as sensor and data sender. Microcontroller detected electrical fault by taking sampling of current and transformed by using discrete wavelete transform method which would given high frequency signal output and would be used to analyzing the signal of electrical fault. The methods of data retrieval was divided into three conditions in order to distinguishing electrical fault by the detection equipment. The three of them were normal condition, switching condition, and arcing condition, and then compared the three characteristics of the condition by the difference of load power and the length of impedance. In this research, the result that obtained was the equipment based on smart phone was able to detecting arc fault and impedance variation was not influence the performance of the detection equipment.
