Concentrator & Edge Intelligence

Data Concentrator Unit (DCU)

HPLCRS-485Edge AnalyticsTopology

Local data collection for transformer-area operations. The DCU aggregates meter and switch data at the transformer area, applies edge analytics, and forwards clean, structured data to the head-end — reducing transmission load and cloud-storage pressure.

Transformer-area network topology visualization and phase identification
Line-loss analysis, power-quality monitoring and fault-event reporting
Seamless access to measuring switches, DIN-rail meters and IoT meter boxes
Edge computing reduces transmission delay, bandwidth load and cloud-storage pressure
