Utilities install and maintain power system protection with the intent to maintain or increase power system reliability. Therefore, protection engineers and technicians should align their testing strategy with this goal. Yet with limited testing time and resources, we have to invest our efforts where we can actually prevent misoperations.Which raises the question: what is causing […]
