- De-energized tap changer (DETC)
- Shielding of frames and tank
- Leads
- Load tap changer, if so equipped
- Bushings
- Preventative auto (reactor)
- Thermal analysis
These analyses will be made using the latest state-of-the-art design programs, including Finite Element Analysis (FEA) and thermal design programs. Also, any upgrades that can be made will be suggested to allow you to bring your Waukesha® or other brand power transformer up to current design standards.
