The indicator provides reliable detection and analysis of electrical faults in medium-voltage networks. By analysing transient current signals and capacitive voltage inputs, it can identify the direction of earth faults and distinguish them from phase-to-phase faults.It is designed to detect high-impedance phase-to-earth faults up to 3 kΩ, helping network operators identify developing faults quickly and improve the safety and reliability of their distribution systems. Phase-to-phase faults are detected using current magnitude and time-based criteria, while fault status is clearly displayed locally and can also be transmitted to a remote control system.The indicator combines advanced fault detection with comprehensive measurement and communication capabilities, including:

• Directional earth-fault detection based on transient current and voltage analysis
• Detection of high-impedance phase-to-earth faults up to 3 kΩ
• 50 Hz sum-threshold detection and short-circuit detection
• Measurement of current, line voltage, residual voltage and load flow
• Event logging and COMTRADE fault recording
• Remote firmware upgrades
• 16 × 3-character LCD with rotary encoder and push-button interface
• Ethernet and RS485/Modbus communication
• Configurable optical digital outputs

With its powerful analysis functions, flexible communication options and user-friendly interface, the indicator is an effective solution for monitoring, diagnosing and managing faults in modern electrical distribution networks.
