Dear Friends
GTG failed to synchronize with grid on automatic selection, machine RPM keep moving between (48-50 HZ) 2880-3000 RPM.
Ideally RPM stabilize near 3000 and minor change in the RPM in order to synchronize but this time machine RPM reach 2995 and start decreasing again and reach lower limit 2880 and start increasing again finally manual option was used to synchronize with the system. it was also observed that Bus frequency was bit higher than the machine.
Synchronizing system indicates voltage matched and frequency matched but phase matched was not appearing.
i will appreciate your input and expert opinion will help me to conclude.
thanks & regards.
