Design Considerations for MOV Block Line Surge Arresters
1
Voltage Rating: Ensure that the MOV arrester you choose has a voltage rating that is equal to or greater than the system voltage.
Testing and Maintenance of MOV Block Line Surge Arresters
Testing and maintenance of MOV line surge arresters is essential in order to ensure they remain effective in protecting against power surges. Testing of the MOV line surge arrester should be done periodically to check for proper operation. This includes visual inspections of the arrester and its components like zinc oxide blocks, as well as testing with a surge testing device. Maintenance of the metal oxide varistor mov should include regular cleaning of the arrester to remove dirt and debris, as well as replacing any components that are worn or damaged. Additionally, the MOV line surge arrester should be checked periodically to ensure it is properly grounded and that the wiring is secure.
