Product Introduction

The ABB SYNPOL D CMA 131 B is a dedicated synchronizing module used in ABB generator control and marine Power Management Systems (PMS). It automatically compares the voltage, frequency, and phase angle of an incoming diesel generator with the live busbar before permitting circuit breaker closing.

This module plays a vital role in ensuring safe parallel operation of multiple generators onboard ships, offshore platforms, and industrial power plants. Incorrect synchronization can cause severe generator damage, breaker failure, or complete power blackout, making the CMA 131 B an essential protection and control component.

SM MARINE SERVICE™ supplies tested ABB CMA 131 B modules, complete ABB SYNPOL D systems, spare parts, repair, calibration, and worldwide technical support.

What is the ABB CMA 131 B?

The CMA 131 B continuously monitors:

• Generator voltage
• Busbar voltage
• Generator frequency
• Bus frequency
• Phase angle
• Synchronizing window
• Breaker closing conditions
• Time delay settings

When all synchronizing parameters are within the allowable limits, the module issues the breaker closing command, enabling safe generator connection to the electrical network.
