Due to the lack of a standard nanosecond high-voltage pulse generator for sensor calibration, a high-stability nanosecond high-voltage pulse test system was developed in terms of circuit analysis, structural design, and performance test. By establishing the equivalent circuit model of the nanosecond pulse generator, the circuit component parameters of the five-stage Marx loop and the one-stage compression steepening unit were simulated. The influence of the action performance of the steepening gap on the characteristics of output nanosecond pulse was analyzed. The nanosecond pulse test system was established through the structural design of the nanosecond pulse-generating circuit, the development of a high-performance corona-stabilized switch, and the measurement of a fast-response resistance divider made of metal oxide thin-film resistors. The nanosecond pulse test system has the capability to output a double exponential nanosecond pulse voltages in the amplitude range of 10–60 kV with a rise time of 2.3 ± 0.5 ns and a half-peak time of 23 ± 5 ns. In addition, the output pulse voltage has a high consistency and stability in the full amplitude range. The maximum relative standard deviation of the peak value is 1.517%, and the relative standard uncertainty is less than 5‰.

This paper presents capacitive sensors based on oxide dielectric substrates that provide a high attenuation factor of up to 30 · 103 with a transient time of ∼38 ps. The sensors made it possible to significantly reduce the number of attenuators and increase the bandwidth of the measuring path. The presented sensors have been used successfully for recording high voltage to MV pulses in the time range from a few nanoseconds to tens of picoseconds. The use of the sensors as the point receiving antennas for recording radio pulses in the GHz frequency range with high electric fields is also discussed, along with the trough directional coupler as a unit for additional attenuation of the voltage of the sensor response. The couplers have a high attenuation factor of 1–5 · 103 with a transient time of ∼38 ps. Using the couplers as attenuators for recording waveforms further improves the parameters (bandwidth, transient time) of the measuring circuit. A discussion of some features of the operational mode of this type of sensor and coupler with a focus on wave processes is also presented. This discussion can be used to analyze the general approaches to the improvement of the sensor and coupler as components of the measuring circuit. In this paper, the authors also propose methods for calibrating and calculating the attenuation factor of the sensors.

In recent years, linearization technology for nonlinear devices has become a hot topic in many fields. In this study, a linear voltage divider based on metal oxide arresters was designed by combining linearization technology and electrical measurement technology to solve the objective problems of online voltage monitoring. These problems include high difficulty in equipment installation, low measurement accuracy, and poor economic benefits. Based on a summary of linearization theory, the sufficient and necessary conditions for the linearization of the voltage divider were deduced in detail. The relevant circuit simulations were conducted, along with voltage divider experiments under power frequency AC voltage, operating overvoltage, and lightning overvoltage. The results revealed that the voltage divider was able to realize linearized measurements and meet the relevant standards of online voltage monitoring. The measurement errors were concentrated in the transition region between the pre-breakdown region (small current region) and the breakdown region (nonlinear region) in the volt–ampere characteristic curve. The main influencing factor of errors was the consistency of the nonlinear characteristics of the high- and low-voltage arms of the voltage divider. The voltage divider designed in this study can be applied in many scenarios, such as power plants, substations, high-voltage electrical equipment manufacturing plants, and high-voltage laboratories.
