I. PRODUCT COMPOSITION & APPLICATIONS
The ETCR EM8080 Wireless Three-Phase Current Monitor employs wireless multi-connection communication technology for online monitoring and recording of three-phase current and phase imbalance. It provides users with three-phase current load trend graphs. Multiple monitors can be deployed to assess transformer zones and branch circuit loads, offering technical support for load transfer operations. Users can view real-time data via Bluetooth on-site or remotely through 4G connectivity. The system includes three detectors, a charging dock, charger, Bluetooth app, and cloud-based management platform.

II. MULTI-CONNECTION COMMUNICATION TECHNOLOGY
The ETCR EM8080 features integrated Bluetooth communication across all three detectors, with the Phase-A unit incorporating 4G connectivity. When clamped onto A/B/C phases, the detectors collect real-time current data, which is aggregated via Bluetooth to the 4G-enabled Phase-A unit. This unit uploads averaged current values to the cloud server for analysis. Users can access data locally via Bluetooth pairing or remotely through the 4G-enabled platform.

III. KEY FEATURES

Multi-connection technology enables communication between devices, mobile apps, and cloud servers.

Records three-phase current averages, peaks, valleys, imbalance rates, and generates time-based trend graphs.

Configure device IDs, sampling intervals, and monitor battery levels via Bluetooth or remote 4G settings.

Ultra-low power consumption ensures extended continuous operation.

Clamp-on design allows non-intrusive installation without circuit interruption.

IP65-rated waterproof/dustproof housing for outdoor durability.

Anti-theft electronic lock controlled via Bluetooth app for secure deployment.

High-capacity lithium battery with extended runtime.

Charging dock supports simultaneous charging for three units.

IV. TRANSFORMER ZONE & BRANCH LOAD MONITORING
In low-voltage power distribution systems, seasonal load fluctuations often cause uneven transformer utilization. Traditional load transfer methods lack data-driven precision, risking overloads or underutilization.

The ETCR EM8080 (Smart Zone Load Transfer Analyzer) enables predictive load management:

Deploy multiple units to monitor candidate circuits pre-transfer

Analyze historical load patterns to optimize redistribution

Visualize phase imbalance and load trends via cloud platform

Prevent overload risks while maintaining optimal 70% transformer utilization

This solution applies to urban grid networks, significantly improving operational safety and energy efficiency.
