“…Intensitas tinggi dari medan listrik yang dihasilkan dapat menyebabkan gangguan udara dan terjadi fenomena petir. Salah satu masalah utama yang dihadapi jaringan listrik adalah tegangan lebih yang disebabkan oleh petir [8]- [9].Terdapat dua kategori utama sambaran petir yaitu langsung dan tidak langsung. Tegangan lebih yang dihasilkan dari sambaran tidak langsung lebih rendah daripada sambaran langsung, yang lebih besar parah dan menyebabkan kerusakan yang lebih serius untuk isolator.…”

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.

“…The conductivity of the metal oxide arrester (MOA) valve plate varies with the impulse voltage value, and the setting of the parameter value directly affects the accuracy of the simulation results [22][23][24]. In order to obtain the nonlinear resistance characteristic, the relation curve between conductivity and voltage has been studied by a relevant experiment.…”

In order to analyze the explosion accidents of the CRH5 EMU roof arrester in recent years, an internal temperature measuring platform based on fluorescence fiber was established, and the temperature distribution characteristics under the continuous operating voltage and high-current impulse were analyzed. The test results show that passing section overvoltage and steep impulse overvoltage have higher amplitudes, while high-harmonic overvoltage has a lower amplitude but a longer duration. The maximum temperature rise of the arrester was 5.2 °C under 34 kV for 3 h. The surface temperature of the valve plate column was high in the middle and low on both sides; the maximum temperature difference at different positions was only 2.2 °C. The maximum temperature of the valve plate column rose to 97.6 °C under 105 times of the high-current impulse, and the maximum temperature difference at different positions reached 33.8 °C. Then, the actual overvoltage of the arrester in operation was measured and analyzed statistically, and the arrester simulation model was established. The temperature characteristics of the normal arrester and the arrester with the electric tree were studied under the actual typical overvoltage, and the influence of air velocity on the internal temperature rise was analyzed. The simulation results show that, due to the low amplitude and small current of high-harmonic overvoltage, the internal temperature rise of the normal and defective arresters was very small. Under the effects of passing section overvoltage and steep impulse overvoltage, the internal temperature of the normal arrester can reach 36.57 °C and 241 °C, and the arrester with the electric tree defect can reach 44.75 °C and 536 °C, respectively. The air velocity has little effect on the internal temperature rise of the arrester. Passing section overvoltage and steep impulse overvoltage occur frequently and have an obvious influence on the internal temperature rise of the arrester, so the roof overvoltage of the EMU is an important reason for the arrester burst.

“…Simulation analysis is critical for large-scale high-voltage electrical equipment since the test analysis is time-consuming, some destructive tests are costly, and the test conditions are strict. In terms of simulation calculations, the electric field distribution [20,21] and temperature field distribution [22][23][24] of arresters are mainly studied. However, there are few achievements in the distribution of magnetic fields.…”

The status of zinc oxide (ZnO) arresters is directly related to the safety of power grids. However, as the service life of ZnO arresters increases, their insulation performance may decrease due to factors such as operating voltage and humidity, which can be identified through the measurement of leakage current. Tunnel magnetoresistance (TMR) sensors with high sensitivity, good temperature stability, and small size are excellent for measuring leakage current. This paper constructs a simulation model of the arrester and investigates the deployment of the TMR current sensor and the size of the magnetic concentrating ring. The arrester’s leakage current magnetic field distribution under different operating conditions is simulated. The simulation model can aid in optimizing the detection of leakage current in arresters using TMR current sensors, and the findings serve as a basis for monitoring the condition of arresters and improving the installation of current sensors. The TMR current sensor design offers potential advantages such as high accuracy, miniaturization, and ease of distributed application measurement, making it suitable for large-scale use. Finally, the validity of the simulations and conclusions is verified through experiments.
