ABB SYNCHROTACT 5 – 3BHB006713R0217 Automatic Generator Synchronizing & Synch-Check Module

The ABB SYNCHROTACT 5 (model 3BHB006713R0217) is designed for fast, reliable generator-to-bus and bus-to-bus synchronization. From my experience, it’s the type of hardware you specify when you want clean close commands and less operator intervention during parallel or reclose operations. It continuously measures generator and busbar voltages, matches frequency/voltage/phase angle within set limits, and compensates for breaker closing time so you land the close at the right angle—typically the first time.

Key Features

• Automatic synchronizing – Matches frequency, voltage, and phase angle between generator and busbar, then issues a close command when conditions are within set windows.
• Synch-check function – Provides an independent permissive to ensure the breaker only closes under safe synchronization limits.
• Dead-bus detection – Detects loss of bus voltage and allows controlled energization when configured.
• Breaker close time compensation – Offsets the command to account for breaker operating time so the contacts close at the target angle.
• Raise/Lower control outputs – Hardwired pulses for governor and AVR trim (speed/voltage), typically simplifying retrofit into existing control loops.
• Flexible operating modes – Auto, semi-auto, and manual assist modes are commonly used for commissioning and plant procedures.
• Robust measurement inputs – Two independent VT inputs (generator and bus) at standard PT secondary levels (commonly 100–120 V AC).
• Status indication – Clear LED and relay status feedback for permissive, closing, and alarm states.
• Industrial-grade design – Built on ABB’s protection platform, typically compliant with IEC 60255 practices for EMI, surge, and temperature.

Technical Specifications

Application Fields

You’ll typically find SYNCHROTACT units in power plants, CHP facilities, industrial utility rooms, data centers, and marine or offshore genset rooms. They’re commonly used for:

• Automatic synchronization of generator breakers to plant busbars or the public grid
• Bus-to-bus transfers during sectionalizing or tie-breaker operations
• Dead-bus energization with controlled close sequence
• Retrofits replacing legacy synchronizers while keeping existing governors/AVRs

“We swapped an aging synchronizer with a SYNCHROTACT 5 and immediately saw more consistent close angles. Startup time dropped because operators weren’t riding the controls.” — Plant Electrical Supervisor (CHP, 20 MW)

Advantages & Value

• Operational reliability – Proven ABB platform; less nuisance trip risk and stable synchronization windows in most cases.
• Compatibility – Works with standard PT/VT secondaries and hardwired raise/lower loops; typically a clean fit in retrofits.
• Reduced commissioning time – Clear parameters for slip, angle, and voltage limits; easier to dial in and repeat.
• Lifecycle support – ABB documentation and spare strategy; straightforward to maintain with basic tools.
• Procurement clarity – Stable lead time, 365-day warranty, and flexible shipment options so projects stay on schedule.

Installation & Maintenance

• Environment – Mount in a clean, ventilated control cabinet; avoid excessive vibration and heat sources. Keep wiring separated from high-EMI runs.
• Wiring – Use correct PT ratios (commonly 100–120 V AC secondary) to GEN and BUS inputs; route shielded pairs where practical. Verify breaker trip/close circuits and interlocks.
• Parameterization – Set slip frequency limits, voltage tolerance, and target phase angle. Enter breaker closing time so compensation is accurate.
• Safety – Lock-out/tag-out before wiring changes. Confirm synch-check permissives in both automatic and manual modes.
• Routine checks – Periodically verify close-angle accuracy, clean terminals, and test binary I/O. Update settings after governor/AVR tuning changes.
• Spare strategy – Keeping one spare unit on-site is common practice for critical generation buses.
