GSU Pad Mount Transformers
Reliable Transformers for Renewable Energy
IT’S IN THE DESIGN – IT’S WHAT’S INSIDE THAT COUNTS
About the Problem:
- Solid state converteriInverters in Type 3 and 4 turbines produce current and harmonics.
- 5-legged and wound core design is most susceptible to harmonics and gassing.
- These harmonics cause localized heating in the core and coil - leading to gassing and accelerated insulation aging.
– GASSING ------------------ LOSS OF LIFE
– DEGASSING --------------- LOSS OF REVENUE
- Design construction of 3-legged core, rectifier type design mitigates heating, gassing, and partial discharge.
- Core flux density designs minimize harmonics and hot spots.
- Electrostatic shields prevent capacitively (coupled transfer of high frequency harmonics from on winding to another).
The Solution:
- 30 years of experience in rectifier transformer design.
- Rectifier duty design mitigates harmonic heating and gassing.
- 3-legged design overcomes gassing.
- Electrostatic shields prevent coupled transfer of harmonics in winding.
- 3-year warranty, including gassing.
