Hi Palletjack, Yes, i am thinking about the 30 degree phase shift, we can compensate for 30 phase shift? We placed the measurement after DY11.

Hi RRaghunath, The slip frequency is ok for 0.25Hz, sometimes we can set it 0.3Hz. If slip is 0.05Hz, then it is very difficult to synch in. The 400V breaker tripped due to OC fault after synchronization happened. Yes, it happened at The First time of commissioning.

Hi RRaghunath, Thanks for your advises. All the PTs are connected on HV 6.3 KV side. The setting for synchronization on the controller : - voltage different: 3% - frequency different: -0. 1 - +0. 15 Hz - Phase angle: -5 degree to + 5 degree. We are checking for wiring of PTs, CTs, phase...

Hi Che Kuan Yau and Muthu, Thank you very much both of you for advises and support. Currently, we are doing the final check for the phase sequence, Step-up transformer and PT as well. after final check we will try to do the synchronizing. If still can not, maybe we need to change the step-up...

hi edison, the lv breaker trip due to overcurrent. the phase sequence is ok at hv side, we checked already. the 400v breaker is normally close. then we syn 6.3kv breaker to the bus as you mentioned. the CT's and PT's all are connected from 6.3kv swithgear to the syn controller. i am just...

Hi Guys! we are doing synchronizing 02 gensets. one is 400v, the other one is 6.3kv genset. we use a step up transformer 400/6.3KV/DY11 to step up the voltage to 6.3kv and doing the synchronizng at 6.3kv side. Attached is single line diagram. The synchronizing controller is easygen 2300. when...
