APPLICATION OF ACTIVE COMPENSATED FOUR-COAXIAL CABLES TO AC RESISTANCE STANDARDS COMPARISON

• Abstract:

  The general features of active connection structures based on four-coaxial cables are summarised and their application to four-port resistance standards to allow them to be compared by means of a conventional transformer bridge is shown. As a test of the measurement method, a comparison between the easurements performed at IEN and at the CTU on a well characterised resistance standard with nominal value equal to the quantised Hall resistance at the i = 2 plateau (12 906,4 W) has been carried out. Some details about the eference resistor, the calculable resistors and the measuring systems are reported together with the results of the comparison.
