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 . ABB offers a complete range of surge arresters for high and medium voltage applications. The range comprises of AC and DC solutions up to 100kV and arresters for special applications like railways, DC-voltage limiting devices and many other purposes.
ABB has more than years of experience in designing and manufacturing surge arresters. ABB surge arresters are made of metal oxide (MO) resistors without spark gaps directly .
A typical surge arrester has both a ground terminal and a high-voltage terminal. When a powerful electric surge travels from the power system to the surge arrester , the high voltage current is sent directly to the insulation or . Cooper Power Systems surge arrester products are manufactured for reliable service in low voltage, distribution, riser pole, intermediate, and station class applications. We offer the largest selection of surge arresters for overhead and underground applications in the industry. Continue reading “Surge arrester”
