Isolation Transformer
Isolation Transformer
(OP)
We have an isolation transformer that steps down voltage (27kv to 2080v) to power an LCI. It's used to start a gas turbine.
How is an Isolation transformer different?

RE: Isolation Transformer
An "isolation" transformer is usually a 1:1 transformer that is put in either to
1. provide a separately derived system with an isolated ground
2. provide a degree of protection against line transients
However, any two-winding transformer is an isolation transformer because of (1) above, as opposed to an autotransformer.
The only ones I know who ever pushed me to install isolation transformers were a couple of mechanical engineer project managers who had to get a line started up, but the VFD's kept tripping on overvoltage. They had "heard of isolation transformers being used before". I resisted the "temptation" and had the utility take down the secondary taps. I have not heard of any problems, and that was 15 years ago.
