“…As mentioned previously in this section, the best fit output stage capacitance must be arrived at by trial-and-error. For this reason, the easiest approach to insert this compensation is to couple it in parallel with the divider's output, in a separate box, in a similar fashion to that has been done by RISE [10]. This way, capacitors can be freely added or removed with no fear of altering any other parameters.…”

A high-precision voltage buffer and a 10:1 resistive voltage divider have been constructed for use in ac voltage and electrical power metrology. Long-term stability of the buffer's dc response has been demonstrated by two dc sweeps performed 20 days apart, with best-fit linearized gain varying less than 1 μV/V. The absolute ac gain has been measured using a high-precision digital multimeter for 10 Hz and 1 kHz with results consistent with dc within 5 μV/V. This value agrees with the characterization of ac–dc difference using thermal converters from different producers with a variety of resistance for various voltages from 1 V to 5 V. The ac–dc difference was further characterized better than 40 μV/V for the same voltages up to 100 kHz and better than 100 μV/V for 3 V at 1 MHz. Absolute ac gain and ac–dc difference has also been measured for the voltage divider and buffer combination from 10 V to 50 V, with similar agreement up to 1 kHz. The ac–dc difference from 10 Hz to 100 kHz of this combination shows an agreement well within 30 μV/V in this entire voltage span with a total response not exceeding 125 μV/V. This make the voltage divider and buffer combination suitable for sampling electrical powers for a wide range of voltages.

“…Another buffer has been constructed together with a 120:4 resistive voltage divider by Lei et al [8], where they have characterized it using a Fluke 5790A. An array of resistive voltage dividers have also been made at the Swedish metrology institute (RISE, earlier SP) [9,10].…”

We present the design and electrical characteristics of an active low-pass filter. It will be used in a reference waveform source based on a programmable Josephson voltage standard with multilevel delta-sigma modulation to generate accurate and spectrally pure arbitrary waveforms. The filter has a fifth-order Butterworth characteristic with high input impedance, low distortion, high stopband attenuation, and stable passband performance, including dc.

“…Disadvantage is slower settling for high voltages. On the other hand, they can be operated even above 100 kHz if properly compensated and/or equipped by buffers [6].…”

The paper describes design of a new multirange AC resistive voltage divider (RVD) for input voltage up to 1 kV for measurement of LF power and power quality parameters. Two prototypes were constructed and characterised in terms of temperature dependence, power dependence of gain and phase errors and AC transfer. The new RVD reached phase change below 0.5 μrad and gain change below 8 μV/V at 53 Hz for voltage step from 100 V to 1 kV with time constant below 2.5 minutes. Voltage dependence and DC ratio stability are under evaluation.
