Power Transformer with Drawn Leads Bushings
Power Transformer with Drawn Leads Bushings
(OP)
For a 60 MVA transformer, 1300 kV BIL, operating at 365 kV continuous:
1) What are the pros and cons of using the drawn Leads bushings versus the fix connection?
2) Are any reliability concerns with this type of bushings particularly with oversize rated BIL but with higher than usual power frequency voltage above 362 kV?

RE: Power Transformer with Drawn Leads Bushings
2) No reliability concerns with good quality draw lead designs which are there for many years.Probably at the BIL mentioned, there are only draw lead or draw rod designs available.
