Desc

The GoWatron GWPR300‑ABT‑B Automatic Bus Transfer and Bus-Tie Protection Relay is designed for automatic source transfer applications in 132 kV, 66 kV, 33 kV and 11 kV power systems. It provides automatic transfer control for incoming circuit breakers and bus-section/bus-tie circuit breakers, together with integrated protection, measurement, monitoring and local/remote control functions.

The relay is equipped with dual Ethernet ports supporting IEC 60870‑5‑103 over Ethernet and IEC 60870‑5‑104. IEC 61850 communication is available as an optional feature.
An RS‑485 serial interface supporting Modbus RTU is also provided.
Supported time-synchronization methods include IRIG‑B, SNTP and protocol-based

GWPR350-HSBT High-Speed Busbar Transfer Device

Desc

The GWPR350‑HSBT High‑Speed Busbar Transfer Device is compatible with 3‑132 kV medium‑ and high‑voltage dual‑power systems; standard 100 V PT secondary input, 5 A / 1 A CT secondary input; supports DC110 V / DC220 V operating power supply.
Primary single‑line configuration: Suitable for single‑busbar and single‑busbar‑sectionalised topologies. Fully supports mutual transfer between incoming feeders and bidirectional transfer logic between incoming feeder and bus‑section breaker.
Applicable loads: Developed for continuous‑process busbars with large‑capacity asynchronous motors. GWPR350‑HSBT replaces conventional time‑delayed automatic bus transfer equipment and mitigates motor shutdown and process interruption caused by grid voltage sags.
Environmental & communication specifications: Operating temperature: -25 ℃ ~ 60 ℃. Standard interfaces include RS485 and Ethernet. Supported protocols: IEC 60870‑5‑103, Modbus; IEC 61850 digital protocol is optional. It supports IRIG‑B code and pulse‑per‑second hardware time‑synchronisation, with station‑wide synchronisation error ≤ 1 ms.
