Circulating currents between secondary wye connected neutrals 1

[rockman7892]

What would happen if the neutrals of secondary wye connected trasnformers were both connected to ground through a Neutral Ground Resistor but had their neutrals tied together on the line side of each ground resistor, or esentially at the neutral bushing of each transformer?

Could there be circultating currents that would result between this connection? What would cause these circulating currents?

fwiw, Nick’s comments made sense to me. If you suspect circulating current, what would be the loop path? (80A doesn’t sound like a realistic capacitively coupled current). Are the transformer secondaries somehow interconnected? Are these autotransformers by any chance?

(2B)+(2B)' ?

If you are feeding a wye:wye transformer with an unbalanced load on the secondary you will have primary neutral currents. These currents may return on the ground or may split between the ground and neutral. What is the nature of the load on the transformers?

All of the loads on the transformer secondary are either Delta connections on the primaly of 4.16kV-480V transformers or MV motors connected either Delta or wye.
