EKL4 Short Circuit and Earth Fault Indicator Tester
Inquire NowDescription
The EKL4 Short Circuit and Earth Fault Indicator Tester is an advanced monitoring device designed for electricity distribution networks, specifically for installation on RMU, cable branch boxes, and substations. This comprehensive unit provides real-time monitoring of short circuits and single-phase ground faults, effectively identifying the fault section in the corresponding cable. When a circuit breakdown occurs, the device promptly alerts staff, enabling rapid fault location and resolution. Its robust design not only enhances operational efficiency but also minimizes blackout duration, optimizing service delivery and economic benefits.
Main Functions:
- Short Circuit Alarm: Measures current, triggering alarms when thresholds are exceeded, and communicates alerts to a central indicator.
- Earth Fault Alarm: Monitors zero sequence current, alerting operators to ground faults.
- Low Voltage Alert: Uses battery power to signal when voltage drops below normal levels.
- Automatic Reset: Resets the device after a designated time unless manually overridden.
- Manual Reset: Operators can acknowledge alerts by pressing a reset button for three seconds.
- Remote Automation: Capable of receiving reset signals and transmitting alarm alerts remotely.
- Self-Test Capability: The device can conduct self-diagnostic tests to ensure functionality.
