HTS Transformer
Benefits of HTS Transformers:Greater efficiency
Smaller, lighter and quieter
Can run indefinitely above rated power without affecting transformer life.
Do not require cooling oil like conventional transformers, thereby eliminating the possibility of oil fires and related environmental hazards.
Characteristics:
Provide more power per unit volume in existing substations
Applications:
Can be sited safely almost anywhere, e.g.:
- high-density urban areas
- inside buildings
HTS Transformer
Project: 1996-2002 - Design and Construction of 5/10 MVA HTS Transformer Prototype
Waukesha Electric Systems (transformer manufacturer)
SuperPower (HTS wire and coil manufacturer)
Rochester Gas & Electric (utility end user)
Oak Ridge National Laboratory (supporting research)
Rensselaer Polytechnic Institute (supporting research)
In early 1998, Waukesha Electric Systems successfully tested a 1 MVA prototype HTS transformer designed and built by this team.
A larger, 5/10 MVA system-level prototype transformer program was subsequently designed and built. While most of the objectives of the 5/10 MVA program were met, an issue with the dielectric system prevented the device from being operated on the grid. Further development work will focus on the use of 2G HTS wire in the device.
Transformers convert generation-level voltage to transmission-level voltage. This reduces the amount of energy lost in the transmission of power over long distances.
