The Impact Of Lightning Arresters On Power Systems And Selection Suggestions

66 kv lightning arrester Impact on power system
Surge tolerance: The higher the Imax, the greater the lightning impulse energy that the 66kv surge arrester module can handle, and it is suitable for areas with high lightning risk. The 69 kv lightning arrester with low Imax may be broken down or fail when facing strong lightning, resulting in 9kv 5ka lightning arrester direct exposure to lightning surges and serious damage 9kv lightning arrester.
Enterprise safety assurance: For power-intensive enterprises, such as data centers and manufacturing plants, choosing high Imax lighting arrester 11kv modules can ensure that key equipment and production lines can still operate safely in thunderstorms, avoiding economic losses caused by production stagnation and equipment damage.
lighting arrester 33kv Selection suggestions
Thunderstorm-prone areas or outdoor electrical equipment should choose lightning arrester 20 kv modules with Imax40kA to 100kA or above to ensure that lightning arrester 22kv can continue to function under multiple lightning strikes.
Enterprise power system protection: Imax should not be less than 20kA to cope with common inductive lightning and operating surges.
