Services
De-Energized Tap Changers
Quality Switch engineers precision de-energized tap changers for transformer voltage regulation. Our designs range from 125A to 2500A with BIL ratings up to 1050 kV, compatible with oil, ester fluids, and air environments. Customizable options ensure optimal integration with distribution and power transformers.
High Voltage Testing
Our Horace H. Sewell High Voltage Testing Center offers 1.2 MV impulse testing and 700 kV partial discharge analysis. These capabilities validate switch performance under extreme conditions, ensuring compliance with IEEE standards and customer specifications for critical electrical infrastructure.
Grounding Switches
Patented Type QS-GBN grounding switches meet IEEE C57.12.40-2024 standards for network protection. Designed for distribution transformers, these switches provide safe, reliable disconnection with 230kV/115kV dual-voltage configurations and 900 kV BIL ratings.
Dual Voltage Switches
Quality Switch develops mechanically linear dual-voltage switches for adaptive transformer applications. These solutions enable seamless transitions between voltage levels (e.g., 230kV X 115kV) while maintaining 900 kV BIL insulation standards and 1000A current capacity.
Custom Switch Design
Our engineering team creates tailored switch designs using SolidWorks 3D modeling and ANSYS finite element analysis. From 200A distribution switches to 1050 kV BIL units, we develop specialized solutions for unique transformer configurations and environmental requirements.
