I am aware of the effects of negative sequence, and how to calculate the amount of negative sequence available in the circuit. I am trying to understand the amount of current that would be available to operate a negative sequence relay if a pole were to open on the low side of the transformer...
I have a generator connected to the grid using a delta-wye transformer. The generator is a 12MVA machine, and runs at 4.16KV. Recently, while it was operating, the C phase opened, however it took longer than we would have expected for the negative sequence relay to operate. I am familiar with...
