Product Description
G3LD (Part‑no.1KHW000886R0102) is fiber‑optic Ethernet communication board for ABB/Hitachi Energy NSD570 teleprotection unit. It plugs into internal slot of NSD570 chassis. It is equipped with SFP slot for fiber‑optic link for teleprotection command transmission between substations. Supports IEC 61850‑GOOSE for trip, permissive and blocking protection commands. Built‑in link supervision, channel fault alarm and hardware self‑diagnosis. It can be combined with G7BI binary I/O board, G1LA power‑line‑carrier board and G1LB E1/T1 board for mixed‑media teleprotection schemes. OEM end‑of‑life, supplied as legacy utility maintenance spare part.

Product Application
- Fiber‑optic pilot‑protection channel: Transmit teleprotection commands between two‑end NSD570 units over fiber links for HV transmission‑line protection.
- Smart‑substation GOOSE tele‑trip: IEC 61850‑GOOSE‑based remote trip / permissive / block signal exchange via fiber‑Ethernet.
- Redundant mixed‑media scheme: Deploy together with E1/T1 or power‑line‑carrier boards for communication‑channel redundancy to improve protection reliability.
- Fault‑board replacement: Direct swap‑out for defective fiber‑communication board inside NSD570 to restore fiber‑link protection signal transmission.
- Utility spare‑parts inventory: Standby spare for HV‑line teleprotection systems to minimize protection‑outage duration.
