Abstract

We are implementing a new standard for 60 Hz mains power based on precision sinusoidal reference voltages from two independent Programmable Josephson Voltage Standards (PJVS) (one for voltage and one for current). Our NIST PJVS systems are based on superconductor - normal metal - superconductor (SNS) junctions. Using step-wise approximation synthesis, the PJVS systems produce sinewaves with precisely calculable rms-value and spectral content. The uncertainty contributions from the Josephson references are expected to be a few parts in 107, which will enable the development of an ac power standard with overall uncertainties at the level of a few parts in 106.
