Hi All

I am looking at transformer protection for upto 70MVA 11/132kV.

Could you help me out with good protection. I know ABB and GEC. Any other in the market place and web address please. I am looking at digital unit all in one complete with software.

Thanks in advance

It seems that you are looking for manufacturers of protective relays.

GE Industrial Systems provides GE Multlin relays

Beckwith Electric Co, Inc.

I recommend the above mentioned web site becasue these provide quite numerous technical documents for protective relays.

In addition the manufacturers listed above, you should look at Schweitzer Engineering Labs,

http://www.selinc.com.

These are very popular in the US.

A checklist of sorts may be IEEE Std C37.91-2000 …Protective Relay Applications to Power Transformers
