A Josephson voltage standard is a complex system that uses a superconductive integrated circuit chip operating at a temperature of 4 K to generate stable voltages that depend only on an applied frequency and fundamental constants. It is an intrinsic standard in the sense that it does not depend on any physical artifact.
It is the most accurate method to generate or measure voltage and, by. Check out NIST Solid State DC Voltage Calibrations, A Sub-PPM Automated Volt DC Measuring System by Bruce E. Field, NBS Measurement Services: Standard Cell Calibrations, also by Bruce E.

A DC power supply usually uses a transformer to convert the voltage from the wall outlet to a different, usually lower, voltage. A rectifier is used to convert alternating voltage to a pulsating direct voltage, followed by a filter, comprising one or more capacitors, resistors, and sometimes inductors, to filter out (smooth) most of the pulsation.
Project staff is also working with the Quantum Voltage project team in Boulder in the development of a 10 V programmable Josephson voltage standard (PJVS). Calibration services, while excellent, are currently at risk, especially dc voltage calibrations.
Since DC current doesn't necessarily cross zero, this type of SSR can't switch DC. (2) There are MOSFET solid state relays that work for DC.
(finally) You should carefully read the datasheet to see what's sort of SSR you have got. \$\endgroup\$ – Nick Alexeev ♦ Dec 9 '14 at Submitted for the panel by its Chair, Gregory E.

Abstract. The paper describes a portable and stable source of AC voltage, current and power. It was developed for use with the NRC Transfer Standard to provide on-site calibrations of the watt and voltampere standards maintained by the metering departments of Canadian electrical utilities in order to establish traceability to the national standard of the National Research Council of Canada (NRC).
The calibration and simulation values in this discussion assume solid state replacements for the 5Y3 and 83 as in Figure 2 5Y3 Solid State Replacement and Figure 1 Type 83 Solid State Replacement. If you use tubes or someone else’s solid state replacement, you should still be able to obtain fairly good results, just not quite as good.
As you may know, voltmeters started as a simple galvanometer meter movement which were attached to an indicating needle which would swing in an arc, usually from left to right in front of a pre-printed number scale with about degrees of free m.The A is an ultra-high accuracy AC/DC Thermal Transfer Standard, designed to meet the most demanding ac traceability requirements.
Using the patented Fluke Calibration RMS sensor and thin film range resistors, the A offers an extraordinary transfer accuracy, with total uncertainties of as low as ±10 ppm (±5 ppm from the National.The idea for this project started way back in – I even found some schematics dating to September of that year.
At that time, I was working on a calibration station for one of our new instruments, and we needed a voltage standard for some of our calibrations.
