Din Rail Mounted Lightning Surge Arrester Customized 3-220kV For Spd Protection

3 Phase Lightning Arrester Din Rail Mounted IEC Standard For Spd Protection

Lightning arrester, surge arrester.
(1) An electrical apparatus used to protect electrical equipment from high transient overvoltage hazards and to limit the duration and often the magnitude of the renewal current. The term includes any external clearance necessary for the normal function of the appliance when installed in operation, regardless of whether it is a component of the whole.
Note 1: Lightning arresters are usually connected between the grid conductors and the ground, however, they are sometimes connected next to the electrical windings or between the conductors.
Note 2: Lightning arresters are sometimes called overvoltage protectors, overvoltage limiters (surge divider)

(2) lightning arrester is another important device often used to prevent lightning damage to communication cables.

Definition
Lightning arrester: An electrical appliance used to protect electrical equipment from high transient overvoltage hazards during lightning strikes and to limit the duration of the renewal current, and often also the renewal current amplitude. Lightning arrester is sometimes also called overvoltage protector, overvoltage limiter. As shown in Figure 1 is a lightning arrester.

Features and Principles 
AC gapless metal oxide lightning arrester has excellent nonlinear volt-ampere characteristics, good response characteristics, no renewal current, large through-current capacity, low residual voltage, strong overvoltage suppression capability, dirt resistance, anti-aging, not subject to altitude constraints, simple structure, no gap, tight sealing, long life, etc.
This arrester in the normal system working voltage, showing high resistance state, only microampere current through. It presents low resistance under the action of over-voltage high current, thus limiting the residual voltage at both ends of the arrester
