“…Deterioration or damage to MOVs results in an increase in the resistive leakage current and a decrease in the dielectric strength of MOVs, which affects the performance of surge arresters equipped with noncompliant MOVs. Therefore, it is imperative to develop reliable MOVs for use in electric power systems and in industrial and consumer electronics and to ensure the adequate monitoring of the condition of MOVs and surge arresters for the safe operation of equipment protected against temporary overvoltages and current surges [ 193 ].…”

This article reviews the progress in developing ZnO-V2O5-based metal oxide varistors (MOVs) using powder metallurgy (PM) techniques. The aim is to create new, advanced ceramic materials for MOVs with comparable or superior functional properties to ZnO-Bi2O3 varistors using fewer dopants. The survey emphasizes the importance of a homogeneous microstructure and desirable varistor properties, such as high nonlinearity (α), low leakage current density (JL), high energy absorption capability, reduced power loss, and stability for reliable MOVs. This study investigates the effect of V2O5 and MO additives on the microstructure, electrical and dielectric properties, and aging behavior of ZnO-based varistors. The findings show that MOVs with 0.25–2 mol.% V2O5 and MO additives sintered in air over 800 °C contain a primary phase of ZnO with a hexagonal wurtzite structure and several secondary phases that impact the MOV performance. The MO additives, such as Bi2O3, In2O3, Sb2O3, transition element oxides, and rare earth oxides, act as ZnO grain growth inhibitors and enhance the density, microstructure homogeneity, and nonlinearity. Refinement of the microstructure of MOVs and consolidation under appropriate PM conditions improve their electrical properties (JL ≤ 0.2 mA/cm2, α of 22–153) and stability. The review recommends further developing and investigating large-sized MOVs from the ZnO-V2O5 systems using these techniques.

“…Oleh sebab itu, prediksi dan lokasi kesalahan yang akurat dan cepat di jaringan distribusi sangat penting untuk meningkatkan keandalan, penyaluran energi listrik yang optimal, dan kepuasan pelanggan dengan pelayanan energi listrik oleh PT. PLN (Persero) terutama di daerah yang jauh dari pembangkit atau pusat pelayanan penyaluran energi listrik [1]- [2]. Salah satu gangguan sistem yang umum dan berdampak negatif pada peralatan distribusi energi listrik adalah tegangan lebih.…”

Pada jaringan distribusi tenaga listrik sering mengalami gangguan yang dapat menyebabkan kerugian , salah satu penyebab gangguan yang terjadi pada jaringan distribusi tenaga listrik adalah sambaran petir yang mengakibatkan tegangan lebih dan dapat merusak peralatan jaringan distribusi, seperti yang terjadi pada Penyulang Glagah PT. PLN (Persero) Distribusi Lamongan. Komponen yang digunakan pada saluran udara sebagai proteksi transformator dari tegangan lebih akibat sambaran petir adalah lightning arrester. Pada penelitian ini, metode yang digunakan adalah metode kuantitatif dengan mengumpulkan data pengukuran peralatan serta data gangguan. Software ATP Draw digunakan sebagai aplikasi simulasi sambaran petir. Kinerja lightning arrester dapat dilihat melalui simulasi sambaran petir yaitu pada section 7 dengan besar asus sambaran 10 kA dan waktu sambaran 0,5 ms yang menyebabkan tegangan lebih hingga 742,47 kV pada fasa R, 702,16 kV pada fasa S, dan 682,18 kV pada fasa T, dengan pemotongan oleh arrester pada waktu yang sama, tegangan menjadi sebesar 20,12 kV pada fasa R, 19,65 kV pada fasa S , dan 4,62 kV pada fasa T. Pada section 6 dengan besar arus sambaran 40 kA dan waktu sambaran 0,6 ms menyebabkan tegangan lebih hingga 2768,20 kV pada fasa R, 2566,60 kV pada fasa S, dan 2546,60 kV pada fasa T, dengan pemotongan oleh arrester pada waktu yang sama, tegangan menjadi sebesar 21,29 kV pada fasa R, 19,09 kV pada fasa S , dan 4,87 kV pada fasa T. Sebagai pencegahan gangguan akibat sambaran petir pada jaringan distribusi tenaga listrik, maka lightning arrester yang terpasang harus dalam kondisi baik tanpa kerusakan.

“…As an alternative to the above online methods, one can highlight the methods which use the monitoring of partial discharges. According to [ 17 ], partial discharges can be measured based on electrical variables (such as current pulses measured with a high frequency current transformer [ 18 ]) or as non-electrical variables (such as sound [ 19 ], light [ 20 ] and electromagnetic waves [ 21 ]).…”

This work presents an innovative application of Frequency Response Analysis (FRA) in order to detect early degradation of Metal Oxide Surge Arresters (MOSAs). This technique has been widely used in power transformers, but has never been applied to MOSAs. It consists in comparisons of spectra, measured at different instants of the lifetime of the arrester. Differences between these spectra are an indicator that some electrical properties of the arrester have changed. An incremental deterioration test has been performed on arrester samples (with controlled circulation of leakage current, which increases the energy dissipation over the device), and the FRA spectra correctly identified the progression of damage. Although preliminary, the FRA results seemed promising, and it is expected that this technology could be used as another diagnostic tool for arresters.
