Power quality measurements improve security of supply

In early June, Fingrid provided its customers with a new extranet service for quality information, thus giving the company’s customers an even more detailed and descriptive picture of electricity quality at their connection points. This makes it easier to monitor the state of the electricity grid and further improve the security of electricity supply.
