Estimating Insulator Contamination from Site Meteorological Parameters (Video)
Knowledge of insulator contamination is critical for correct insulation coordination but its estimation is not easy since it depends on insulator type and the environment where it is installed. Shape, material, orientation also play a role in deposition of contamination and efficacy of natural washing. Read More >
Application Strategies for Offline Measurement of PD in Power Cables (Video)
PD testing is to identify presence of latent, localized electrical discharges in a cable circuit which occur either within the insulation material, at the interface between a metallic and dielectric surface or at the interface between two dielectric surfaces. These are caused by decomposition of air in voids leading to degradation of the dielectric. Read More >
