Which destructive outcome occurs in power transmission networks given increasing reactive power load?

A)Ferranti effect raises receiving voltage
B)Dielectric current causes cable disintegration
C)Corona discharge causes gradual insulation breakdown
D)Skin effect increases conductor resistance

💡 Explanation

Increased reactive power causes raised voltage stress; the resulting ionization uses `corona discharge` due to strong electric fields, which degrades insulating materials. This causes arcing; therefore, leading to gradual catastrophic failure rather than the Ferranti effect under light load.
