Surge arresters are designed to protect electrical equipment from damaging effects of spikes and transients caused by lightning, utility switching, isolation arcing, electrical motor cycling, or any other sudden change in electrical power flow on incoming AC power lines. 

And these devices also provide ideal protection for outdoor lighting and pole lamps, panel boards, workshops, refrigeration systems, electric motors and controls, heat pumps and air conditioning equipment, and many other electrical devices.

The Ceramic gas discharge tube can be used in all places that have over-voltages.We should decide the parameter of the GDTs base on the need of the actual circuit and then select the suitable GDTs,
otherwise,we may get the reverse result.The following is the notice when using  the Ceramic gas discharge tubes:

1)Must avoid affecting the normal operation of circuit when using the Ceramic gas discharge tube.
2)Confirm the maximum peak voltage that the circuit can bear,make sure that the GDT's impulse spark-over voltage must be lower than it
3)Based on the possible impulse current energy to select the necessary impulse discharge current volume of  the Ceramic gas discharge tube
4)When the over-voltage disappears, the GDTs must extinguish rapidly to avoid affecting the normal operation of the circuit.
5)If over-voltage lasts significantly longer, GDT's discharge may continue for an extended period and generate significant thermal energy
6)Select suitable volume of  the Ceramic gas discharge tube according to the applied space.

Gas discharge tube generally uses ceramic as its packing housing. The discharge tube is filled with inert gases with stable electrical characteristics and provided with structure of two or three electrodes .When certain voltage is applied to inter-electrode of discharge tube, nonuniform electric field will be produced. Gases begin to ionize under the effect of electric field. When applied voltage reaches inter-electrode field intensity and exceeds the insulation strength of inert gas, the electric arc will be produced between the electrodes to ionize gas, and the negative resistance characteristic will be produced. 

Thus, the insulation state will be turned into conductive state immediately. i.e. when electric field strength exceeds the puncture strength of gas, the gap discharge will be caused, and inter-electrode voltage will be limited. That is to say, when there is no surge, it will be in the state of open circuit. When surge occurs, the electrode plates in the discharge tube close and connect,allowing harmful current to be discharged via ground wire or circuit loop. 

When surge disappears, the discharge tube restores to the state of high impedance rapidly, and the circuit continues to work properly.

Telephone / fax / modem protection

Telephones, faxes and modems are equipped with sophisticated but sensitive electronics. Typical circuits used to protect them with surge arresters are shown in following Fig.

These arresters protect against common-mode interference voltages, i.e. surge voltages that appear in both lines to ground. In the event of an over voltage, the arrester protects both exchange lines by conducting the surge current away to ground.
