Gas Discharge Tube Arresters (GDT)

A gas discharge tube or GDT, is a sealed, glass-enclosed device that contains an inert gas mixture trapped between two electrodes. When a voltage greater than the GDT's rating is exceeded, the increased voltage ionizes the gas allowing it to conduct electricity and divert the excess voltage to ground.
