Assessing Condition of Substation Surge Arresters
Explosive failure involving porcelain-housed arresters presents an unacceptable risk not only for maintenance staff but also for nearby apparatus. In addition, ageing arresters mean reduced overvoltage protection, especially for older equipment, and this can result in accelerated degradation of their insulation systems. Read More >
Frequency Dependent Temporary Overvoltage EMT Model for Gapless Metal-Oxide Surge Arresters
As power systems evolve with increased cable deployment and renewable integration, harmonic resonances during switching operations create complex overvoltage stresses that traditional power-frequency models cannot adequately assess. Read More >
