ABB SYN5202-0277 3BHB006715R0277 SYNCHROTACT 5 Automatic Dual-Channel Synchronizer

The ABB SYN5202-0277 (3BHB006715R0277) is a dual-channel automatic synchronizer and synchrocheck unit from the SYNCHROTACT 5 series. It performs automatic synchronization of synchronous generators with the grid, paralleling of busbars or lines, and provides synchrocheck functionality for manual operations. The dual-channel design uses differently structured independent processors for enhanced security. It supports up to seven parameter sets for multiple paralleling points and integrates easily with control systems via communication options.

Ideal for power plants, substations, and industrial generation facilities, it ensures breaker closing only under safe synchronous conditions, preventing equipment damage and network disturbances.

• Dual-Channel Architecture: Two independent channels in one casing for high safety against incorrect paralleling.

• Automatic Synchronization: Includes voltage and frequency matching with command generation for precise breaker closing.

• Synchrocheck Functionality: Monitors paralleling conditions for manual or automatic operations, including dead bus (voltage-free lines).

• Multiple Parameter Sets: Up to 7 configurable sets for different paralleling points.

• Flexible Communication: Options for Modbus, Profibus, LON, or IEC 61850.

• User-Friendly Commissioning: Front panel controls or SynView PC software with real-time displays, transient recorder, and event logging.

• High Reliability: Designed for demanding power system environments with robust isolation and EMC compliance.

• Compact Design: Plug-in casing with optional surface mounting.
