Common Fault Analysis and Systematic Maintenance Solutions for Fault Current Limiters (FCL)

Introduction​The Fault Current Limiter (FCL) is a critical protection device in modern power systems. It is designed to rapidly limit fault currents during system failures such as short circuits, thereby protecting key equipment in the grid from damage and ensuring stable system operation. However, during actual operation, the current limiter itself may also fail due to various reasons. To ensure its reliability, systematic prevention and maintenance strategies must be developed for common faul
