Instantaneous Specific Protection Method Against Faulty Synchronizations of Synchronous Machines

open access: yesIEEE Access, 2021
The probability of faulty synchronization of a generator is very small, but not impossible. The main cause of a faulty synchronization is due to wiring errors caused during maintenance or commissioning when voltage transformer and synchronizing equipment
