Basler Electric BE1-25A Automatic Synchronizer

The Basler Electric BE1-25A Automatic Synchronizer is a microprocessor-based system designed for precise generator synchronization to a power system. It automatically adjusts the incoming generator’s speed and phase to match the system, ensuring a smooth, transient-free connection by minimizing differences in speed, voltage, and phase angle at the moment of circuit breaker closure. This unit is engineered to reduce stress on equipment and enhance system stability, operating effectively with a wide range of prime movers, from slow-responding hydroturbines to fast-responding gas and diesel engines. The BE1-25A calculates an anticipatory close signal based on the breaker’s closing time and the measured slip frequency, ensuring the breaker contacts close when the phase angle is near zero.
