...for equipment connected to AC power lines.The role of gas discharge tube (GDT) surge arresters specifically designed for AC power line protection will also be discussed. The first step in providing an effective defense against power line transients is to accurately characterize the transients. One good...

The Gas Discharge Tube (G.D.T.) operates as a voltage dependent switch. When a voltage appears across the device which is greater than its breakdown voltage, known as the Sparkover Voltage, an arc discharge takes place within the tube which creates a low impedance path by which the surge current...

...with repetitive stress and a relatively large slope resistance. Gas-Filled Surge Arresters. Much larger transient currents can be handled by the various gas-discharge suppressor devices. In such suppressors, two or more. electrodes are accurately spaced within a sealed high pressure inert gas environment...

In a gas-tube arrester, the. impedance. commutation voltage spikes, etc.These tran-. low impedance of the arc after sparkover. sients are easy to suppress since...
