Abstract
Pada studi ini dilakukan implementasi dari tegangan tinggi Tesla berbasis solid state coil untuk pengujian isolasi. Pengujian isolasi dilakukan dengan memvariasikan jarak elektroda, jenis elektroda dan frekuensi tegangan uji. Jenis elektroda yang digunakan adalah elektroda runcing, elektroda bola dan elektroda datar. Variasi jarak elektroda pada pengujian isolasi adalah sebesar 0,7cm dan 1,4cm. Variasi frekuensi yang diuji sebesar 4,4kHz, 8,8kHz, dan 13,2kHz. Pengujian isolator keramik pada variasi elektroda datar, bola dan runcing berturut-turut mengalami penurunan tegangan tembus sebesar 11,6%, 14,9% dan 18,6% dari tegangan tembusnya pada frekuensi 4,4kHz yaitu sebesar 2,86 kV, 2,07 kV, dan 1,94 kV. Penurunan tegangan tembus yang terjadi pada kedua isolator tersebut terjadi seiring kenaikan frekuensi sebesar 4,4kHz, 8,8kHz dan 13,2kHz. Nilai frekuensi akan berpengaruh pada nilai reaktansi kapasitif isolator yang diuji, di mana semakin besar frekuensi akan menyebabkan tegangan tembus yang semakin kecil. Nilai tegangan tembus pengujian isolator menggunakan transformator tesla dibandingkan dengan nilai tegangan tembus menggunakan trafo uji. Nilai perbandingan rata-rata pengujian tegangan tembus menggunakan trafo uji dan transformator tesla frekuensi 4,4kHz, 8,8kHz dan 13,2kHz berturut-turut didapatkan sebesar 7,6, 8,2 dan 8,6. Perbandingan yang besar tersebut terjadi diakibatkan beda frekuensi yang sangat besar antara kedua pengujian tersebut. Berdasarkan pengujian yang dilakukan dapat disimpulkan pengujian menggunakan Transformator Tesla dapat dijadikan salah satu alternatif untuk pengujian isolator.

In this study, a high-voltage Tesla based on a solid-state coil was implemented for insulation testing. Insulation testing is carried out by varying the electrode spacing, the type of electrode, and the test voltage frequency. The types of electrodes used are pointed, ball, and flat. The variation of the electrode distance in the isolation test was 0.7cm and 1.4cm. The frequency variations tested were 4.4kHz, 8.8kHz and 13.2kHz. Testing of ceramic insulators on variations of flat, ball and pointed electrodes, respectively, decreased the breakdown voltage by 11.6%, 14.9% and 18.6% of the breakdown voltage at a frequency of 4.4kHz. The breakdown voltage in the two isolators decreased as the frequency increased by 4.4kHz, 8.8kHz and 13.2kHz. The frequency value will affect the capacitive reactance value of the tested insulator, where the more significant the frequency, the lower the breakdown voltage. The breakdown voltage value of the insulator test using the Tesla transformer is compared to the breakdown voltage value using the test transformer. The average comparison value of testing using a test transformer and a tesla transformer with a frequency of 4.4kHz, 8.8kHz and 13.2kHz was obtained at 7.6, 8.2 and 8.6, respectively. This significant comparison occurs due to the large frequency difference between the two tests. Based on the tests carried out, it can be concluded that testing using a Tesla Transformer can be used as an alternative for insulator testing.
