I am new to this forum and I appreciate all comments.
We are a natural gas combined cycle power plant located in Los Angeles, CA. We had a transformer failure and are thinking about replacing our 1988 60 MVA transformer (106,200 pounds) with a new 75 MVA transformer (199,852). The pad in the center of our containment is 11’x7’ and the 75MVA pad requires 13’x 8.5’. We are trying to answer the following questions:
We are a natural gas combined cycle power plant located in Los Angeles, CA. We had a transformer failure and are thinking about replacing our 1988 60 MVA transformer (106,200 pounds) with a new 75 MVA transformer (199,852). The pad in the center of our containment is 11’x7’ and the 75MVA pad requires 13’x 8.5’. We are trying to answer the following questions:
- Are there new codes (seismic/weight) that we must meet if we put in a new pad? If yes, where can I find the statute?
- What triggers the change in code ie if we remove our current transformer from the pad will we be mandated to change vs repair the current transformer on site and don’t have to change the pad vs install the new 75 MVA transformer and increase the size of the pad?
- If the volume of the containment is capable of handling the new 75 MVA oil volume, which it is, is it possible to replace just the pad and not the containment?
- Can anyone suggest engineering and concrete firms in Los Angeles familiar with transformer pads?
