Multijunction thermal converters as the NBS primary AC-DC transfer standards for AC current and voltage measurements

摘要

A set of multijunction thermal converters (MJTC's) has been established as the NBS primary ac-dc transfer standard for ac current and voltage measurements. This choice is based upon the advantages of the MJTC's, the development of an improved EMF comparator, an extensive series of intercomparisons, and numerous supporting investigations.
