At present, my country uses a large number of gapless zinc oxide lightning arresters. In high-voltage AC power systems, zinc oxide lightning arresters are usually used in conjunction with lightning arrester online monitors. The monitors are used to monitor leakage current and the number of lightning arrester discharges.
