“We’re pleased that Svenska kraftnät has chosen Metrum as its supplier, and we look forward to continuing our collaboration in order to strengthen the Swedish electricity grid and make it possible to take preventive measures to optimise operations,” says Robert Olofsson, CEO, Metrum.
Metrum’s PQR control meters have been installed in all substations (400/130 kV) for continuous metering of both electric-power quality and energy. Svenska kraftnät has also installed Metrum SC instruments to measure the substations’ auxiliary power.
Metrum is already a system supplier to Svenska kraftnät and, in addition to its control meters, the company has also delivered a large number of substation meters to measure auxiliary power, HVDC meters and meters for proactive disturbance analysis and fault detection.
Svenska kraftnät uses Metrum PQ Controller DB, which is Metrum’s comprehensive collection and analysis system for conducting ongoing analyses. Svenska kraftnät has also integrated Metrum’s system into a number of external systems to maximise the utilisation of collected measurement data.
