Howdy everyone,
I have a question or two. I currently have a project where I am out for tender for a couple of 20mva (CSA C-88) 55C ONAN 69kv delta - 13.8kv wye step-down transformers. I have asked for pricing for both a sealed-tank design and a conservator-tank type design. The pricing that I have received in real close for both design types (like within 2%).
BTW These transformers will be installed in a wet marine type of environment.
I did a quick search for the ENG-TIPS forums and found out that to my surprise that most of the transformers installed in this class of power transformer were in fact of the sealed-tank design. This surprised me in that I had incorrectly assumed that most of the installed base would be of the conservator-tank design type.
What is the experience that you all have had with this class of transformer? What are the pros & cons of the two design types?
Thanx much,
GG
