The Grid Reliability Risk Hiding on High-Voltage Insulation
by Contributed Content from POWER Magazine on (#78RFB)
A high-voltage insulator can look unchanged for years while its operating environment steadily alters the conditions on its surface. Salt carried inland from a coast, industrial residue, road dust, moisture, ultraviolet radiation, and repeated weather cycles create an exposure history that can influence electrical performance and maintenance demands long before an asset reaches a predetermined [...]
