Composite Insulator Performance in Aggressive Environments: Comparison vs. Coated Glass
by Samuel Arturo Asto Soto

Coastal Peru is characterized by high salt pollution, high humidity and scarce rainfall and it is critical to find the most effective and reliable insulation to allow power system reliability and security. This presentation details experience with different insulator technologies in such an environment and compares performance of RTV coated glass and composite insulators so as to determine proper maintenance needs and best replacement strategy.
