An electrical arrester is a protective device that safeguards power systems and sensitive equipment from transient overvoltages caused by lightning or switching impulses. It functions by instantly diverting harmful high-voltage surges to the ground, and then returns to its normal non-conductive state once the surge passes.Arresters operate on a straightforward principle and come in a few common configurations:How They Work: During normal operation, an arrester acts as an insulator. When a severe voltage spike hits the power line, the arrester's internal resistance drops dramatically, providing a low-impedance path to harmlessly discharge the current into the earth.Metal Oxide Varistors (MOVs): Most modern surge and lightning arresters use metal oxide blocks. These materials act as non-linear resistors, instantly changing their resistance.
