Different 15kv lightning arrester lightning protection levels correspond to different voltage protection levels (Up). T1-level lightning arrester in transformer has a higher Up (generally 2.5kV to 4kV), T2-level high voltage lightning arrester has a lower Up (1.5kV to 2.5kV), and T3-level 33kv lightning arrester has the lowest Up (1kV to 1.2kV). These 10 kv lightning arrester types reduce surge voltage in a layered manner, ensuring that terminal equipment always operates within a safe voltage range.
