“…Meanwhile, after the high voltage is removed, the charge in the depth also dissipates quickly. Similar charge phenomena are also found in our previous research studies under DC and polarity reversal conditions [25][26][27][28], which found that the charge accumulation also appears at the beginning of the voltage application or state transition. This kind of charge accumulation is mainly due to the rapid migration speed of space charge.…”

The charge phenomena under sine and half-wave sine voltages within the frequency range of 500 Hz are studied here. Based on the pulsed electro-acoustic method, the traditional circuit design under high-frequency voltages is first analysed. It is found that the selection of a 186 pF protection capacitor and a 333 kΩ protection resistor can ensure that the actual voltage applied to the sample is consistent with the expected input. Based on this design, experimental results show that the polarity of the charge accumulated in the depth of the sample is determined by that of the upper electrode. Comparison results under special voltages with different amplitudes and frequencies indicate that the amount of accumulated charge under sine voltages are larger than those under positive and negative half-wave sine and DC conditions, and the samples under lower-frequency conditions show more charge accumulation. The maximum electric field strengths appear at 90 and 270 degrees of the sine voltage with a frequency of 10 Hz, and their values are 68.55 and 81.82 kV/mm, respectively. Therefore, the charge characteristics are easily affected by the voltage's waveform and frequency parameters. The results obtained here can provide guidance for the application of insulating materials under special voltage environments.This is an open access article under the terms of the Creative Commons Attribution-NonCommercial-NoDerivs License, which permits use and distribution in any medium, provided the original work is properly cited, the use is non-commercial and no modifications or adaptations are made.

“…Different insulating materials also show varying trap characteristics [7]- [9]. The existing researches under special electrical stresses within 500 Hz and polarity reversal conditions show that the accumulation of space charge can form instantaneously at the moment of voltage application or state transition [10]- [12]. Thus, a high measurement speed of charge methods is a necessary basis for tracking such fast-migrating charges.…”

The resolution performance of space charge measurement method determines its application environment and measured information, which has put forward higher temporal and spatial resolution requirements for the charge evaluation of electronic equipment insulation. Based on the ellipsometry detection principle and the photoelastic effect of the sensor, a novel optical method for space charge measurement is proposed. The potentials of the method in terms of single measurement with high signal-to-noise ratio, terahertz bandwidth and nanometer spatial resolution are analyzed. By deriving the mathematical relationship of the signal transmission, it is indicated that the light intensity difference measured by the system can linearly present the elastic force generated from space charge. Based on the built ellipsometry detection system, it is found that the detected signal from the sensor can quickly track the imposed elastic waves with different amplitudes and frequencies, which verifies the feasibility of the crucial detection part and the fast measurement speed of the proposed method. Further simulation results indicate that the refractivity performance of the sensor under the effect of elastic waves can present the deformation variation with a spatial resolution of 2 nm. Therefore, the given explorative research can provide the key theoretical basis and experimental verification for the proposed method.
