Description
Product Overview
ABB 3BHB006716R0217 (SYN5302A-Z V217) is a dual-channel digital synchronizer belonging to ABB SYNCHROTACT 5 generator synchronisation family. It performs high-precision automatic paralleling control for generators, matching voltage magnitude, frequency and phase angle between generator and grid before closing the circuit breaker. It integrates with ABB UNITROL excitation systems, AC800PEC controllers and substation automation platforms. Widely deployed in thermal, hydro and gas turbine power plants, it is a critical spare for generator grid connection retrofit and maintenance.

Installation & Testing Notes
- Mount 3BHB006716R0217 into generator control cabinet rack
- Connect PT voltage signals, breaker control wiring and LON communication cable strictly per single line diagram
- Verify auxiliary power and protective grounding before energizing voltage input circuits
- After power-up, configure generator parameters via front keypad or remote engineering tool
- Perform static synchronisation simulation test to validate phase/voltage/frequency measurement
- This module does NOT support hot swap. Isolate control power and PT secondary circuits before removal
- Complete full on-load synchronisation commissioning after replacement
- Periodically inspect voltage wiring terminals in high vibration power plant cabinets
