SURGE PROTECTOR & ARRESTOR
|
 |
Varistors are voltage-dependent, nonlinear device, which have an electrical behavior similar to back-to-back zener diodes. They are used for absorption of transient voltage, suppression of pulse noise and circuit voltage stabilization. The varistor's stand-by state has a higher impedance (several mega-ohms) compare to the component to be protected and does not affect the characteristics of the electric circuit. In the presence of transient voltage (over the breakdown voltage of varistor), the varistor then has low impedance (a few ohms) and short circuit, thus the assembly device is protected. GDT (Gas Discharge Tube) components operate when a surge exceeds the rated-working-voltage of GDT. As the arc with high current (because of low impedance of GDT) is ignited, GDT can prevent a further rise of surge voltage. It is commonly used as a protector for data communication and fire alarm circuit. |
