Thank you all, and before I close this matter, like to share a different case of switching on a much larger transformer rated 20 MVA, 22 kV primary voltage with secondary open circuited, as follows:-
Afrer demagnetize the 20 MVA transformer,the inrush current was in the range less than 350%...
Thank you all for replies, and insight provided.
I do not have the budget for CSD, and also this is LV switching unlike HV and MV with more budget. I will adopt an economical yet difficult method as I am switching on LV Breakers which do not have CSD functionality found in HV and MV.
What I...
Hi Participants out there,
I have an interesting problem to solve , as you all know that switching on an unloaded txf can see 5 to 10 time its rated current, depending on any remnant magnetism , and point of voltage at instant of turning on.
I intend to use soft starter, and ramp the voltage up...
