Distribution Automation Terminals
FTU Feeder Automation Terminal
The feeder automation terminal (FTU) provides fault diagnosis, fault isolation, power restoration, circuit-breaker control, measurement and monitoring for distribution network lines at 13.8kV and below.
It collects, processes and analyzes real-time measurements and remote-signaling data from the distribution network, enabling the dispatch center to monitor network conditions and make operating decisions. Remote control enables equipment operation from the control center, shortening fault-clearing time and reducing labor intensity.

Isolation and Shielding
- Multi-stage isolation and effective shielding are incorporated throughout the enclosure, PCB design and component selection to resist interference.
Standardized Manufacturing
- Mature surface-mount technology and manufacturing processes following ISO9000:2000 procedures support electromagnetic compatibility and reliable field operation.
Built-in Backup Power
- Includes a built-in backup power supply.
High-precision Measurement and Energy Metering
- Provides Class 0.5 energy metering.
Comprehensive Event Records
- Stores up to 2048 events covering protection operation, alarms and status changes, plus 1024 operation records.
Multiple Setting Groups
- Supports four setting groups (groups 0-3) for different operating modes.
Remote Settings and Software Protection Control
- Supports remote setting adjustment and software-based protection enable/disable control.
Auxiliary Software Tools
- Auxiliary software enables waveform data reading and analysis, online software upgrades and remote setting adjustment.
Configurable Protection
- Protection modules can be enabled or disabled through the configuration menu. Software protection controls and settings for disabled modules are hidden.
