Corona is a serious issue in metal clad switchgear because of its highly destructive nature. It is the cause of most flashovers in medium-voltage metal clad electrical equipment. The fundamental cause of this symptom is an electrical breakdown of air brought on by electrical stress and poor air quality within the switchgear. If not rectified a flashover is imminent, possibly causing enormous damage and injury to personnel.
With today's instruments used for condition monitoring and predictive maintenance, Highvec is able to help combat and verify this problem.
