about transformer ....please help
(OP)
Hi all
This is jaser, I just graduated and I'm working in radio station(mid-voltage 11kv ). most equipments feed by 11kv and our load reach 4Mw
so we have two supply for our station:
1- from Public electricity (33kv) and we switch it to 11kv by transformer 33kv/11kv.
2- from our generators give 11kv.
now public electricity company wants to change the line from 33kv to 13.8kv
so our options is:
1- change all equipments from 11kv to 13.8kv and take the power directly from the electricity, no need transformer.
(this option seems impossible, it will cost alot).
2- change our transformer from 33kv/11kv to 13.8kv/11kv to match new feeder (13.8kv).
( it seems reasonable)
My question To experts
What would you like to Recommend
I'm worried if we change the transformer.
will the transformer work fine or we will face troubles with heating and efficiency and we need to change the transformer time to time.
please help.

RE: about transformer ....please help
the most simple solution is to change the existing 33kV/11kV transformer with a new 13.8/11 kV one. If the neutral grounding is not a concern you could use an autotransformer, being the co-ratio extremely favorable.
New autotransformer losses will probably be very lower if compared to the existing transformer.
