Feeder Terminal Unit (FTU)
Model:
Overview:
The Feeder Terminal Unit is a product specifically designed to monitor and protect pole-mounted switches in a 10KV distribution network. It possesses fault detection, protection control, and communication (once a communication module is configured). It is suitable for use with switches installed at the responsibility demarcation point of the user's incoming line on 10kV overhead distribution lines and eligible branch lines. The terminal, along with the pole-mounted switch and voltage transformer, constitutes a complete set of equipment. After being matched, it can automatically remove the single-phase ground fault of the controlled branch line and automatically isolate the interphase short-circuit fault of the controlled branch line.

· Rapid Fault Isolation: Capable of quickly isolating in-zone faults;

· Advanced System Architecture: Employs a 32-bit microprocessor platform with a reserved Ethernet communication interface to meet power system digitalization requirements;

· Integrated Prepayment Control: Combines protection and monitoring functions and uses GPRS for communication with the control center to implement a prepayment control function with compatible energy meters;

· Enhanced Anti-Theft Capability: Expandable feature to enforce a power trip (forced disconnection) upon unauthorized opening of the metering cabinet door, providing an anti-theft function;

· Flexible Ground Protection: Ground protection can be selected as either directional or non-directional, and binary (switch) signals are software-invertible;

· Dual Fault Management: The controller is designed to handle the two main 10kV fault types phase-to-phase short circuits and single-phase ground faults separately;

· Four-Shot Auto-Reclosing: Features a four-shot automatic recloser with a configurable accelerated closing after reclose function.
