Surge Arrestor - High-voltage Protection Device , Efficient Transient Voltage Suppression And Lightning Surge Mitigation

We are considered as a reputed firm, we are engaged in manufacturing, supplying and exporting a wide range of Surge Arrestor. A surge arrester is a device to protect electrical equipment from over-voltage transients caused by external lightning) or internal (switching) events. Also called a surge protection device (SPD) or transient voltage surge suppressor (TVSS), this class of device is used to protect equipment in power transmission and distribution systems. (For consumer equipment protection, different products called surge protectors are used.)

To protect a unit of equipment from transients occurring on an attached conductor, a surge arrester is connected to the conductor just before it enters the equipment. The surge arrester is also connected to ground and functions by routing energy from an over-voltage transient to ground if one occurs, while isolating the conductor from ground at normal operating voltages. This is usually achieved through use of a varistor, which has substantially different resistances at different voltages.
