“…Voltage dividers have played and still play a strategic role in metrology for low and high DC [5][6][7][8][9][10][11][12][13][14], AC [15][16][17][18] and impulse voltages [19][20][21] At INRIM, a test set-up involving a divider with a sinusoidal and a LI generators has been simulated with the LT-spice program. Simulations with single generators (LI and sinusoidal) and with composite voltages have been carried out.…”

In the framework of the European Project 19NRM07 HV-com2 supporting the standardization in high-voltage testing with composite and combined wave shapes, a divider to employ in a test set-up for validation of electrical devices submitted to composite voltages below 1 kV has been developed at the Istituto Nazionale di Ricerca Metrologica (INRIM) and currently is under extensive testing. After a simulation stage, an available divider has been modified to comply with the IEC 60,060 requirements in terms of step response and scale factor. To be suitably fast in replying to step voltages, an adjustment of the components of the low-voltage arm has been made. The divider has been calibrated with traceability to the relevant INRIM National Standards and characterized exploiting its scale factor at different voltages and frequencies. The divider has been then inserted in a set-up with a sinusoidal generator, an impulse generator and coupling–blocking elements to carry out tests at low voltages (below 1 kV) with single voltages. In these tests, the divider showed a satisfactory attitude as converting device and its scale factor is traceable with suitable uncertainty.

“…To extend the frequency range of such RC dividers, it is advisable to include additional damping resistors to the capacitive branch, thus forming a so-called "universal voltage divider" (RCR divider). Due to the frequency independence of such universal voltage dividers over a wide range, these dividers offer the unique advantage of being able to measure AC, DC and impulse voltages (comprehensive discourse by HARADA in [7]). The need to perform tests for the emerging HVDC technology has recently led to a wider application of these dividers.…”

“…Capacitive-resistive combined dividers are more likely to be used in practical applications. The parallel-connected resistive-capacitive voltage divider developed by T. Harada has a step response time of about 10 ns [18]. Sweden developed an HVDC voltage divider based on RC compound connection, which has an uncertainty of 16 × 10 −6 in DC measurement [19].…”

The on-site measurement of transient voltages is of great significance in analyzing the fault cause of power systems and optimizing the insulation coordination of power equipment. Conventional voltage transformers normally have a narrow bandwidth and are unable to accurately measure various transient voltages in power systems. In this paper, a wideband parallel resistive–capacitive voltage divider is developed, which can be used for online monitoring of transient voltages in a 220 kV power grid. The structures of the high-voltage and low-voltage arms were designed. The internal electric field distribution of the high-voltage arm was analyzed. The influence factors and improvement techniques of the upper frequency limit were studied. The parameters of the elements of the divider were determined. The voltage withstand performances and scale factors under lightning impulses and AC and DC voltages, the temperature stabilities of scale factors and the step response and bandwidth of the developed voltage divider were tested. The results show that the deviations of the scale factors under various voltage waveforms and different temperatures ranging from −20 to 40 °C are within 3%. The withstand voltage meets the relevant requirements specified in IEC60071-1-2011. The step response 10~90% rise time is approximately 29 ns, and the 3 dB bandwidth covers the range of DC to 10 MHz.
