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 CONVERTER/INVERTERS IN TYPE 3 AND 4 TURBINES PRODUCE CURRENT AND VOLTAGE HARMONICS
- 5-LEGGED AND WOUND CORE DESIGN S MOST SUSEPTABLE 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 - 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 ONE WINDING TO ANOTHER)
The Solution:
- 30 YEARS 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
A 25 YEAR LIFE Protected by Patents
