The EKL-4 Panel-type Grounding and Short-Circuit Fault Indicator is a panel-mounted (cabinet-mounted) intelligent fault detection device.
It’s used in 6-35kV distribution network systems, to monitor the grounding faults and phase-to-phase short-circuit faults of the lines in real time, and provide local fault location indications for maintenance personnel through distinct indicator lights.
• Panel-mounted installation: Directly integrated into the instrument door of the switch cabinet, without the need to modify the main circuit.
• Dual-fault identification: It can accurately distinguish between short-circuit faults (where current surges) and grounding faults (in small current systems).
• Intelligent anti-interference: Capable of identifying interference such as closing surge current, and avoiding false alarms.
• Multiple reset methods: Support automatic delay reset, manual button reset, and remote reset (optional).
• Intuitive status indication: The fault type and operating status are clearly displayed through red/yellow/green LED lights.
