Analysis Of The Application Scenarios Of Surge Arresters In Different Electrical Systems

Low-voltage systems commonly employ 22 kv lightning arrester models suitable for branch circuits or terminal points, designed to work with distribution panels to withstand overvoltage surges from external interconnected lines or internal switching operations. Models like 220 kv lightning arrester are suitable for environments surrounding commercial buildings, control cabinets, and external terminal equipment.

High-energy power facilities typically employ 33 kv lighting arrester units with higher rated voltages and enhanced discharge capabilities. These 33 kv lightning arrester units are frequently installed near main power entry points or primary transformer installations to withstand high-amplitude overvoltages from direct or nearby lightning strikes, adhering to standard high-voltage application design principles.
