Power Quality

The quality of electrical power is essential for the smooth operation of equipment and networks. The disturbances of the network (from photovoltaic installations to the dimmers) cause disturbances on several levels. Reducing the risk of a power blackout calls for ever closer monitoring of the electricity grid. This is increasingly being carried out by so-called phasor measurement units (PMUs) and Power Quality Analysers which are tested and calibrated traceable by METAS.
