In order to ensure the normal operation of the lightning arrester, the following work needs to be carried out regularly:

Visual inspection: check whether the lightning arrester bracket, lead wire and grounding wire are intact.
Internal inspection: check the metal zinc oxide element of the lightning arrester for damage or aging.
Cleaning and maintenance: regular cleaning and maintenance to ensure the normal operation of the arrester.
Test: Measure the discharge current and operating voltage of the arrester, and monitor the lightning protection.
When the lightning arrester fails, the following treatment methods can be adopted:

Replacement treatment: when the metal zinc oxide element of the lightning arrester is aged or damaged, the lightning arrester should be replaced with a new one in time.
Maintenance processing: maintenance processing by professional technicians to ensure the safety of the maintenance process.
Upgrade processing: When the technical level of the arrester cannot keep up with the development of the times or needs to meet the new lightning protection requirements, it can be upgraded to improve its performance and reliability.
