“…Studi menunjukkan bahwa sifat PD tergantung pada tegangan yang diberikan dan frekuensi tetapi tidak terpengaruh oleh tegangan offset yang diterapkan [1]. Analisis PD digunakan untuk menilai berbagai bahan isolasi seperti LDPE, XLPE, nano polimer isolasi bahan dan jenis lain dari polimer [2][3][4][5][6][7][8][9][10].…”

Abstrak-Korelasi antara jumlah pulsa peluahan sebagian (PD) dengan tingkat kerusakan permukaan sampel dikaji dalam makalah ini. Pengkajian dilakukan dengan menguji sampel berbeda dari komposit polietilen berkerapatan rendah (LDPE) dan karet alam (NR) di bawah pengaruh medan listrik tinggi selama 60 menit. Hasil memperlihatkan adanya korelasi yang kuat antara citra permukaan sampel setelah pengujian dengan jumlah pulsa PD yang terhitung. Jumlah pulsa PD yang tinggi berkorelasi dengan luas citra pemukaan sampel rusak yang lebih besar. Kata Kunci : peluahan sebagian, komposit, polietilen, karet alam, citra permukaanAbstract-The correlation between the partial discharge (PD) pulses count and the surface of the related sample was studied and reported in this paper. The assessment was done by testing different samples of the composite low density polyethylene (LDPE) and natural rubber (NR) under a high electric field for 60 minutes. The results showed a strong correlation between the images of the sample surface after testing by the number of PD pulses is counted. The high of PD pulses counted are highly correlated with the larger scale of surface area damaged.

“…The PD pulse shape characterised by the rise and fall times, width and height contain information about the discharge mechanisms as well as the nature of the defect such as dimensions and aging. The PD pulse features have been studied directly [1,3,5,8] or used as inputs into computational intelligence PD classification techniques [9] or analysed in the frequency domain through Fast Fourier Transform (FFT) techniques [10]. PD diagnostic technology uses different test voltage magnitudes and frequencies for various reasons [11][12][13][14].…”

A study on the influence of supply voltage magnitude and frequency on partial discharge (PD) pulse shapes is presented in this paper. Ultrawide band (UWB) timeresolved PD pulse measurements were carried out on artificial PD defects using test voltage frequency range of 10 -400 Hz and voltage range of 2 -11 kV. The manner in which the PD pulse shape responded to changes in the test voltage characteristics depended on the defect type. The observations can be interpreted using the generally agreed theory of PD mechanisms. The knowledge generated in this work is valuable in the interpretation and comparison of PD measurements made at different voltages and frequencies. It also contributes to development of PD defect classification techniques based on the correlation between test voltage frequency and time-resolved PD.Index Terms -Partial discharges, pulse parameters, supply voltage magnitude and frequency.

The majority of PD monitoring is performed on cables operating under AC conditions, however, the increasing use of high voltage DC links, for subsea, or long land-based connections provides motivation for the increased use of PD monitoring on cables operating under HVDC. However, despite the increased intensity of research into PD in HVDC cables, there are significant knowledge gaps, preventing the practical application of PD monitoring techniques to HVDC cables. This paper seeks to partially address these gaps in knowledge, by presenting results obtained from PD measurements on artificial voids created in polymeric cable insulation under both AC and DC conditions. This work was presented at the 21 st IEEE International Pulsed Power Conference.
