This article discusses the outcome of DC voltage ratio comparison CCEM-K8 that was participated by fifteen National Metrology Institutes. The need for a key comparison of DC voltage ratio was recognized by the Comite’ International d’electricite’ et Magnetisme (CCEM) at its 20th meeting in June 1995. Its purpose was to compare the scaling capabilities in DC voltage of the National Metrology Institutes (NMI) up to 1000v. After preliminary studies carried out at IEN [1], a Daltron 4902s voltage divider(s/n20.335) as the traveling standard was adopted to normalize the participants’ results, the calculation of the key comparison reference values and the comparison results were reported for the two mandatory ratios of the comparison, 1000v/10v and 100v/ 10v. More detailed informational and the results for the optional measurement can be found in the comparison final report [3].

Author:West, NJ; Jandrell, IR; Forbes, ADate:Aug 2008The aim of this paper is to compare the electrical performance of an orthogonally with a coaxially laser-triggered spark gap. Each of these two gaps has its own advantages and disadvantages. At the same time, a Rogowski profile spark gap was ...Read more
