China Manufactured Arrester Monitoring Calibrator
Lightning arrester monitors are widely used in substations across China, where their operational status directly impacts power system safety. These monitors track lightning arrester actions and leakage current. However, factors like moisture ingress due to poor sealing can cause component rusting, leading to counter malfunctions or inaccurate current readings. Annual inspections are mandated by regulations, making this instrument an essential tool for maintenance.
