The National Laboratory for High voltage and High current

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


Measurements are made all over the world, in all sectors. Usually we measure in order to make decisions or to control something. It can be to decide on certain actions, but it can also be automated decisions in industry control- o…

Calibration high voltage &amp; current measuring equipment (National Lab)

The mission for RISE&#039;s High voltage group is to provide state-of-the-art calibrations of measuring equipment used in high voltage and high current testing. Within the high voltage area we have resources for DC and AC line fre…

Testing of high voltage equipment

We perform testing of products, components and materials, such as power cables, pre-fabricated substations and much more.

Energy system analysis

We make analyses of local, regional and national energy systems focused on societal benefits to provide information for investments, policy and business models. The analyses are performed using a systems perspective and often incl…

Calibration of electrical power at The National Laboratory

Power meters, watt meters and converters (transducers) measure the electrical power and are available both as single and multi-phase. Calibration of a power meter or watt meter ensures that the error of the dsiplayed measurement v…


The climate challenge coupled with society’s need for energy demand new, sustainable, competitive and flexible solutions. National goals such as fossil-free electricity generation by 2040, a fossil fuel-independent vehicle fleet b…
