EM8080 Wireless Three-Phase Current Monitor, also known as a three-phase imbalance analyzer, is used to monitor and record three-phase current data and analyze three-phase imbalances in power lines. It provides accurate data for load redistribution in transformer districts, prevents indiscriminate load shedding, effectively resolves issues of severe load imbalance in transformer districts, and offers a technical solution to ensure the safe and economical operation of equipment.
EM8080 Wireless Three-Phase Current Monitor consists of three current clamps and a cloud-based backend system. It employs a multi-connection communication method, with all three clamps featuring built-in Bluetooth connectivity; Clamp A also includes built-in 4G connectivity. During operation, the three current clamps are attached to the A, B, and C phases of the power transmission line, respectively. The clamps collect real-time data on the three-phase currents of each branch, The system then calculates the average current over a unit of time (15 minutes) and stores this data in the device’s flash memory. At the top of every 15-minute interval, the Phase B and Phase C units transmit their average current values for that period via Bluetooth to the Phase A clamp, which features 4G connectivity. The Phase A current clamp uploads the average current values for each phase over the specified time period to the backend server. Users can access the backend or connect to the Phase A current clamp via Bluetooth on their mobile devices to import the three-phase current data, allowing them to view the three-phase load current data and trends.
