China Manufactured Arrester Monitoring Calibrator
Lightning arrester monitors are widely used in substations throughout China, where their operational status directly impacts power system safety. These monitors track lightning arrester actions and leakage current. However, poor sealing can allow moisture ingress, leading to component rust and inaccurate readings. Annual inspections are mandated by regulations, making this calibrator an essential tool for maintenance.
