[0002] A lightning arrester is an electrical device used to protect electrical equipment from high transient overvoltages and limit the duration and often the amplitude of the follow-on current. This term includes any external clearances necessary for the proper function of the device during operation and installation, regardless of whether it is an integral component. It is used to protect electrical equipment from high transient overvoltages during lightning strikes and limit the duration and often the amplitude of the follow-on current. Lightning arresters are sometimes also called overvoltage protectors or overvoltage limiters. AC gapless metal oxide arresters are used to protect the insulation of AC power transmission and transformation equipment from lightning overvoltages and switching overvoltages. They are suitable for overvoltage protection of transformers, transmission lines, distribution panels, switchgear, power meter boxes, vacuum switches, shunt compensation capacitors, rotating motors, and semiconductor devices. There are many types of lightning arresters, including metal oxide arresters, line-type metal oxide arresters, gapless line-type metal oxide arresters, fully insulated composite-jacketed metal oxide arresters, and removable arresters.
