Hi Guys,
I’d like to know if any of you have a similar experience and kindly give your analysis on this situation: High impedance relay for bus protection (SEL 587Z) trips during switching of load on one particular feeder only.
Details:

Guys,
In a WYE(G) - wye (g) transformer configuration, some utilities simply utilize single-bushing units.
However, the transformers could be subjected to full line voltage once neutral is disconnected from ground and one line opens.
I need your experiences and comments here... Thanks...
All,
Good Day!
I would like to inquire what Transformer Bank Configuration is currently practiced by your utility for three-phase distribution to customers.
For example, we are using Y - delta(center-tapped) but are planning to change it since we are encountering voltage problems during...
