LRG - What factors and configurations could go wrong?
LRG - What factors and configurations could go wrong?
(OP)
we have a situation where equipment fed from the secondary of a 132-13.2Y/7.62kV, 40MVA delta-wye(grounded) transformer with secondary LRG (400A) got damaged.
Equipment damaged include
1- A transfomer connceted delta wye(solidly grounded) which was fed from the secondary of the above mentioned transformer.
2- PTS connected in a similar fashion as #2.
I was not involved in the process and don't know much detail. Just wanted to get an idea, since I have a curious nature.
Could anyone explain why?

Probably not without at least some information on what was damaged and the type of damage.
My first guess is that it was struck by a meteor.

I highly respect your opinion and have learned tremendously from your posts, no matter how harsh they are at times :)
My questions is:
Is it ok to connect delta-wye(grounded) transformer on the secondary side of a detla-wye(low resistance grounded) transformer?
Yes or No?
