Understanding Synchronization in Power Systems
Synchronization is the process of aligning the voltage, frequency, and phase angle of a generator with the electrical grid prior to connection. Synchronization ensures that no electrical surges, system instability, or equipment damage occurs.
A synchronization relay such as the Deif HAS-111DG guarantees:
Voltage Matching – The voltage of the generator is matched to the grid voltage.
Frequency Matching – The generator frequency is synchronized with the grid frequency.
Phase Angle Matching – Guarantees the phase angle is accurate prior to closing the breaker.
Safe Circuit Breaker Closing – Regulates breaker timing to prevent power outages.
The 100V AC breaker closing system in the HAS-111DG enables controlled and safe connection of power sources, eliminating electrical faults.
