Abstract
Pengembangan sistem grid, membuat peralatan tegangan tinggi menerima medan yang besar, sehingga sinyal harmonik yang dihasilkan akan merusak sistem isolasi. Gangguan frekuensi tinggi ini menyebar ke seluruh kabel dan menyebabkan over voltage, sehingga memunculkan partial discharge(PD). PD dapat menghasilkan gelombang elektromagnetik sehingga dapat dideteksi. Studi ini merupakan pengembangan studi sebelumnya, yaitu mendeteksi single source partial dicharge menggunakan beberapa macam antena. Studi ini dilakukan dengan mendeteksi multi source partial dicharge(MSPD) pada isolasi udara menggunakan antena loop. Elektroda yang digunakan adalah elektroda sharp-plane dan flat-plane dengan variasi jarak 0,7 cm dan 1,4 cm. Pemilihan kedua pasang elektroda tersebut karena ketidakhomogen yang tinggi sehingga memudahkan untuk mendeteksi MSPD. Pengujian juga dilakukan dengan memvariasikan jarak antena terhadap elektroda uji sebesar 10 cm, 20 cm, dan 30 cm untuk mengetahui jarak performansi antena. Proses pengambilan data hanya pada kondisi pre-breakdown dengan menggunakan pembangkitan tegangan tinggi AC. Data yang dideteksi antena loop akan dibandingkan dengan HFCT dan diolah dengan menggunakan metode Phase Resolved Partial Discharge(PRPD). Hasil pengujian menunjukkan bahwa antena loop dapat digunakan untuk mendeteksi MSPD pada isolasi udara, hal ini dibuktikan sinyal MSPD yang dideteksi oleh HFCT dan antena loop terjadi pada phasa yang sama. Hasil pengolahan PRPD menunjukkan bahwa variasi jarak antar elektroda mempengaruhi jumlah titik PRPD, semakin jauh jarak antar elektroda maka jumlah titik PRPD akan semakin banyak. Antena loop bekerja optimal dalam mendeteksi MSPD ketika berjarak dekat dengan 2 sumber PD, yaitu pada jarak antena 10 cm.

The development of a grid system, making high voltage equipment receive a large field so that the resulting harmonic signals will damage the isolation system. This high-frequency disturbance spreads throughout the cable and causes over-voltage, giving rise to partial discharge (PD). PD can produce electromagnetic waves so they can be detected. This study is a development of previous studies, namely detecting a single source partial charged using several types of antennas. This study was conducted by detecting a multi-source partial charge (MSPD) in air isolation using a loop antenna. The electrodes used are electrodes sharp -plane and flat-plane with a distance variation of 0.7 cm and 1.4 cm. The selection of the two electrode pairs was due to high homogeneity making it easier to detect MSPD. Tests are also carried out by varying the antenna distance to the test electrodes of 10 cm, 20 cm, and 30 cm to determine the antenna performance distance. The process of data retrieval is only in the pre-breakdown condition by using an AC high voltage generator. Data detected by the loop antenna will be compared with HFCT and processed using the Phase Resolved Partial Discharge (PRPD) method. The test results show that the loop antenna can be used to detect MSPD in air isolation, this is evidenced by the MSPD signal detected by HFCT and the loop antenna occurring at the same phase. The results of PRPD processing show that the variations in the distance between the electrodes affect the number of PRPD points, the farther the distance between the electrodes the more number of PRPD points. Loop antenna works optimally in detecting MSPD when it is close to 2 PD sources, namely at an antenna distance of 10 cm.
