Interference with radio and television (RI and TVI) may arise when electrical discharges run on insulators and inject high-frequency currents into associated conductors, which radiate electromagnetic waves. Audible noise (AN) is generated either by electrical discharges or by an entirely different process, resonance in cavities of insulators, excited
