Application Range:
The leakage monitor & phase wire identified device (model: YJLZ-A) performs leakage current measurement, data recording, alarming, GPRS communication, and phase wire identification. Equipped with a built-in high-accuracy zero sequence CT utilizing magnetic shielding technology, this device ensures high precision and powerful anti-interference capabilities. It is ideally applied in electricity management, communication sectors, and industrial/mining enterprises.
🔔 Leakage Alarm
Users can set alarm thresholds. The device provides sound and light warnings and proactively uploads alarm information to the APP client when detected leakage current exceeds the threshold.
📁 Leakage Data Log
When enabled, the device saves measured leakage current and timestamps into a built-in SD card. Historical data can be viewed via the APP or a computer after importing.
📱 APP Remote Monitoring
A single APP client can manage hundreds of devices. Users can set thresholds, view historical data, and receive real-time leakage alerts remotely.
🛡️ Non-contact Phase Identification
Identifies phase wires using the CT coupling method. This eliminates the need for direct contact with power lines, ensuring personal security.
