Characterisation of thermal converters with a Josephson standard

By developing new methods for characterising thermal converters, an independent realisation of the SI units for alternating voltage (V), alternating current (A) and electrical power (W) will be established at RISE. This will lead …

Ac-Realisation of Resistance with Graphene

This project aims to establish a primary realisation of ac resistance at RISE through ac measurements of the quantum Hall effect (QHE) in graphene. This will lead to a significantly reduced measurement uncertainty for ac resistanc…

Programmable graphene resistance standards

The project will develop and test programmable resistance standards of graphene.

Calibration of inductance

The national Laboratory for electrical quantities offer calibration of inductance standards and various types of instruments, such as bridges, LCR-meters and inductive voltage dividers.

Calibration of capacitance

The national Laboratory for electrical quantities offer calibration of capacitance standards (capacitance and dissipation factor) and different kinds of instruments. For example, electrometers, calibrators, and LCR-meters.

Electric voltage

Electric dc voltage is an area of expertise at the National Measurement Laboratory for Electrical Quantities. We realise the unit related to electrical potential difference (voltage), volt, by utilizing the Josephson effect. …

The National Laboratory for Electrical Q

RISE is Sweden's NMI (National Metrology Institute) and is, according to the Swedish constitution, responsible for the fundamental measurement quantities in the International System of Units, SI.

Electrical resistance

Electrical resistance is an area of expertise at the National Measurement Laboratory for Electrical Quantities. At our laboratory the resistance unit is realised  with the highest possible accuracy. In addition…
