“…The standards also recommend that the dynamic behavior of the measurement system can be evaluated by using parameters obtained from the step response, but a more reliable and simplified method prescribed by the standard is based on simultaneous measurements of a high-voltage impulse by an independent reference system and the system under test. As a first step, international comparative measurements were made in four national laboratories and the relative differences among them were reported [22]. Investigations have also been made of the interactions between two systems configured for simultaneous measurements and of methods for minimizing these interactions [9].…”

A facility has been developed for the determination of the ratio of pulse high voltage dividers over the range from 10 kV to 300 kV using comparative techniques with Kerr electro-optic voltage measurement systems and reference resistive voltage dividers. Pulse voltage ratios of test dividers can be determined with relative expanded uncertainties of 0.4 % (coverage factor k = 2 and thus a two standard deviation estimate) or less using the complementary resistive divider/Kerr cell reference systems. This paper describes the facility and specialized procedures used at NIST for the determination of test voltage divider ratios through comparative techniques. The error sources and special considerations in the construction and use of reference voltage dividers to minimize errors are discussed, and estimates of the measurement uncertainties are presented.

“…The first step by CIGRE WG 33.03 to place impulse voltage measurements on the same basis as other measurements investigated the procedure for, and the possible level of agreement that could be obtained from, international comparisons of reference measuring systems under a variety of conditions and waveforms [6]. The work described in this paper concentrated on documenting the best agreement that could be obtained when comparing resistor dividers.…”

“…In 1986, NRC and CERL exchanged transfer reference dividers (duplicates of their reference dividers), as part of a linked series of measurements with NIST (USA) and PTB (Germany) for the first high voltage impulse comparison by designated National Laboratories. These tests were performed under the auspices of CIGRE Working Group (WG) 33-03 and the results were reported to the meeting of WG 33-03 in Beijing [5] and published in the IEEE TRANSACTIONS ON POWER DELIVERY [6]. Manuscript IEC Publication 60 060-2:1994 specifies comparative measurement against a reference measuring system as the preferred method for calibration of approved measuring systems [reference method to be used to resolve disputes (clause 6.2 of [2])].…”

This paper describes high voltage impulse measurements made under the controlled conditions of a calibration or national measurement laboratory to establish the best agreement that could be achieved in comparison measurements on small reference dividers. This comparison to establish mutual international traceability between NRC and National Grid has shown that the peak voltage of a smooth lightning impulse was measured by both laboratories to within 0.2% with an estimated uncertainty of 0 2% at a level of confidence not less than 95%. The authors make recommendations on how calibrations of reference measuring systems should be performed.
