Data Collection Terminal
IFT-LZ01 Intelligent Fusion Terminal
The IFT-LZ01 Intelligent Fusion Terminal integrates a topology-identification system-on-chip to support operation and maintenance of low-voltage distribution transformer service areas.
Using small-signal injection and HPLC dynamic routing, it builds low-voltage topology maps and customer-to-transformer relationship models for line-loss analysis, electricity theft analysis and equipment fault location. Local edge computing works with the HES to provide hourly and segment-level line-loss statistics and abnormality analysis.
The terminal actively reports outages, distinguishes between individual-customer and whole-transformer outages, and connects with maintenance apps to shorten repair times. It combines multiple data sources to monitor transformer voltage, load, three-phase imbalance and power factor, improving low-voltage network maintenance and supply reliability.
