Varistors can be used for lightning protection of various equipment such as power lines, communication lines, and data lines. Lightning strikes can cause atmospheric overvoltages. Most of them belong to inductive overvoltage. The overvoltage caused by lightning strike on the transmission line is called direct lightning overvoltage, and its voltage value is particularly high, up to 102~104V, causing great harm.
The use of ZnO varistor arresters is very effective in eliminating atmospheric overvoltages. It is generally connected in parallel with electrical equipment. If the electrical equipment requires very low residual voltage, multi-level protection can be used.
