Abstract
Isolator pada system tenaga listrik sangatlah penting untuk memisahkan dua ata lebih penghantar listrik yang bertegangan. Tujuan dilakukan pemisahan tersebut adalah menghindari lompatan listrik atau percikan. Isolasi udara merupakan salah satu isolasi yang umum digunakan pada peralatan tegangan tinggi. Peralatan dapat rusak saat terjadi kegagalan (breakdown) isolasi karena adanya arc, suhu yang sangat panas dan karbonisasi. Kegagalan akan ditandai dengan adanya fenomena Partial Discharge saat kondisi pre-breakdown. Berdasarkan kondisi tersebut tugas akhir ini membahas metode deteksi Partial Discharge pada isolasi udara dengan menggunakan loop antenna. penelitian ini menganalisa pengaruh variabel jarak dan diameter dari elektroda pengujian. Analisa yang dilakukan menggunakan metode PRPD (Phase-Resolved Partial Discharge). Kondisi yang dianalisa mulai dari ketika normal hingga munculnya arus bocor (leakage current). Hasil analisa menggunakan loop antenna akan dibandingkan dengan metode leakage current. Analisa leakage current menggunakan High Frequency Current Transformer. Tujuan dan manfaat dari tugas akhir ini adalah mengantisipasi adanya kegagalan (breakdown) pada isolasi udara. Melalui pengujian ini diharahapkan dapat diketahui bahwa gelombang elektromagnetik yang dihasilkan ketika PD muncul, akan semakin jelas apabila tegangan dan jarak antar elektroda semakin tinggi. Selain itu dapat diketahui bahwa loop antenna lebih unggul dibandingkan metode leakage current dengan HFCT karena kondisi PD dapat dianalisa lebih mudah dengan sudut PD lebih besar. Tugas akhir ini juga diharapkan dapat diimplementasikan untuk menunjang kebutuhan industri di Indonesia. Selain itu, analisa Tugas akhir ini diharapkan dapat dijadikan referensi untuk penelitian selanjutnya.

Isolator in electrical power system is crucial to separate two or more electrical conductors. Separation of electrical conductors is meant to prevent electrical current jump or sparks. Gas isolation is one of the most used types of isolators that are applicated in high voltage appliances. Harm to equipment may happen in result of failure or breakdown of isolator due to arc which is very high and carbonated air. Failure of isolators may be observed through the phenomenon called Partial Discharge (PD) in pre-breakdown state. Based on this condition, this research will analyze methods of Partial Discharge detection in gas isolator using loop antenna. This research will analyze the leverage of distance variable and diameter of electrode used. Analyzation will be done with the implementation of Phase-Resolved Partial Discharge (PRPD) method. Conditions to be analyzed will start from normal state until the signs of leakage current is evident. The output achieved from the loop antenna will be compared with leakage current method for validation. High Frequency Current Transformer (HFCT) will be implemented to analyze leakage current. The purpose of this research is to anticipate failure or breakdown in gas isolator. Through this research, it is expected that electromagnetic waves could be known when PD starts to show, will become more evident with the increase of voltage and distance from the electrodes. Moreover, validation that loop antenna is more accurate rather than the leakage current method with HFCT could also be proven since the condition of PD could be easier to analyze with higher degree of PD. This research is aimed to be implemented to answer the challenges of industrial needs in Indonesia. Lastly, this research is hoped to be a reference for next corresponding researches.
