Abstract

Kabel NA2XSY merupakan kabel dengan isolasi XLPE, namun jointing kabel adalah titik lemah pada kabel NA2XSY. Partial discharge merupakan salah satu fenomena yang biasa terjadi di jointing kabel NA2XSY, PD terjadi karena adanya defect yang terjadi di kabel saat proses jointing kabel seperti semiconductor-tip, metal-tip, ring-cut, dan lain-lain. Penelitian ini akan memodelkan dan menganalisis karakteristik partial discharge akibat defect-defect tersebut menggunakan metode Phase Resolve Partial Discharge (PRPD). Penelitian ini menggunakan kabel NA2XSY dengan nominal tegangan 12/20 kV dan variasi tegangan AC untuk melihat karakteristik partial discharge di jointing kabel yang memiliki defect. Proses dilakukan dengan membuat pemodelan jointing kabel yang di beri defect. Pengujian dilakukan dengan menggunakan seumber tegangan AC serta sensor HFCT untuk menangkap sinyal PD. Data yang didapatkan akan dianalisis menggunakan metode PRPD dan diolah dengan MATLAB untuk menghasilkan pola sinyal PD dari masing-masing defect. Dari penelitian ini akan memberikan hasil pola partial discharge yang konsisten sehingga dapat di temukan karakteristik dari kabel NA2XSY 12/20 kV yang memiliki defect semiconductor-tip, metal-tip, dan ring-cut. Hasil yang diharapkan dari penelitian ini adalah ditemukannya pola sinyal PD yang khas untuk masing-masing jenis defect. Penelitian ini diharapkan dapat memberikan kontribusi nyata dalam meningkatkan keandalan dan keamanan sistem distribusi tenaga listrik melalui identifikasi dini kerusakan pada sistem isolasi kabel.

In The NA2XSY cable is a type of cable insulated with XLPE. However, the cable jointing area is considered the weakest point in this type of cable. Partial discharge (PD) is a common phenomenon that occurs in the jointing area of NA2XSY cables, often caused by defects introduced during the jointing process such as semiconductor-tip, metal-tip, ring-cut, and others. This study aims to model and analyze the characteristics of partial discharge resulting from these defects using the Phase Resolved Partial Discharge (PRPD) method. The research utilizes NA2XSY cable with a rated voltage of 12/20 kV and applies varying levels of AC voltage to observe the partial discharge characteristics in jointed cables with defects. The process involves creating cable joint models with intentional defects. Testing is conducted using an AC voltage source and an HFCT sensor to capture the PD signals. The obtained data are analyzed using the PRPD method and processed with MATLAB to generate PD signal patterns for each defect type. This study is expected to yield consistent partial discharge patterns that enable the identification of specific characteristics of NA2XSY 12/20 kV cables with semiconductor-tip, metal-tip, and ring-cut defects. The anticipated result is the discovery of distinct PD signal patterns for each defect type. Ultimately, this research is expected to provide a significant contribution to improving the reliability and safety of electrical distribution systems through early detection of insulation failures in power cables.
