The Clamp-on Earth Leakage Monitor & Logger (Model: YJLZ-A) is an intelligent, multi-functional device designed for proactive electrical safety management and maintenance. It integrates high-precision leakage current detection, AC current measurement, and non-contact phase identification into one portable, user-friendly tool. With built-in GPRS/USB communication and extensive data logging capabilities, it enables real-time remote monitoring and historical analysis of electrical system health, helping to prevent accidents, ensure personnel safety, and improve operational reliability.1.Functions: Leakage Current Detection, AC Current Measurement, Non-contact Phase IdentificationReal-time Leakage Alarm: Users can set custom alarm thresholds. The device triggers audible and visual alarms locally and pushes instant notification to the mobile App when leakage exceeds the set limit.
Continuous Data Logging: Automatically records leakage current values with timestamps to the internal memory. Historical data can be reviewed directly on the device, via the App, or exported to a PC for in-depth analysis.
Centralized Remote Management & Monitoring: A single mobile App can centrally manage dozens to thousands of devices. Remotely configure alarm settings, view live/data, and receive alerts, enabling large-scale electrical safety oversight.
Safe, Non-contact Phase Identification: Utilizes transformer coupling technology to identify live wires without physical contact, ensuring operator safety during diagnostics.
Professional PC Analysis Software: Companion software allows users to download logged data and generate intuitive Leakage Current vs. Time graphs, providing clear visualization of trends and pinpointing intermittent faults.
High Reliability & Anti-interference: Equipped with a built-in high-precision zero-sequence current transformer and magnetic shielding technology, ensuring accurate measurements even in electrically noisy environments.
