A New Approach to High Voltage Insulation System Testing

Speed is the driving force of successful fault prevention. Early detection of insulation deterioration is key for avoiding asset failure, associated unplanned outages, and physical damage to infrastructure. The traditional testing approaches most teams rely on inhibit quick diagnosis of insulation issues, as they require a wide range of sensing methods and expert data interpretation.
High voltage equipment is especially susceptible to electrical, mechanical, and thermal stresses that can accelerate insulation deterioration and asset failure....
