Which risk increases to ceramic insulators when ambient humidity rises?

💡 Explanation

Humid environments increase surface conductivity because water molecules facilitate ionic conduction of mobile ions on the ceramic surface, therefore surface conductivity increases, rather than resisting current because of increased dielectric strength under dry conditions.
