In the power system, zinc oxide surge arresters play a crucial role as the "guardian" of the grid, effectively preventing damage to equipment caused by lightning or operational overvoltage. To ensure that this' guardian angel 'is always in good working condition, we need to rely on some professional' physical examination tools', among which the 'zinc oxide lightning arrester tester' is an indispensable tool.
What is a zinc oxide lightning arrester tester?
Simply put, a zinc oxide lightning arrester tester is an instrument specifically designed to test the performance of zinc oxide lightning arresters. It evaluates the insulation condition, aging degree, and whether it can still provide effective overvoltage protection by measuring various key electrical parameters of the lightning arrester. Just like conducting annual inspections on cars, lightning arresters also need to undergo regular "health checks" in order to detect potential problems in a timely manner and avoid "running with problems".
What are the "hidden killers" that affect the performance of lightning arresters?
Environmental factors: Long term exposure to humid, polluted, or high-temperature environments can accelerate the aging of lightning arresters and affect their insulation performance.
Running time: Any device has a service life, and over time, the zinc oxide sheet inside the lightning arrester will gradually age, leading to an increase in leakage current.
Operating overvoltage: Frequent operation of overvoltage surges can accelerate the loss of lightning arresters and reduce their protective capabilities.
Manufacturing process: The manufacturing quality of the lightning arrester itself will also directly affect its long-term stability.
