Integrated Software Platform for CVT, CT & IVT Design and Assessment
Wisegrid Energy develops engineering-grade software platforms for the design, optimization, and validation of capacitive voltage transformers (CVTs). In addition, it functions as an IVT design platform. By integrating design methodology, optimization, standard compliance, and EMT-based performance validation into a single unified system, it provides a comprehensive and streamlined solution for transformer design.
Solving Industry Challenges and Enhancing Performance Efficiency
Traditionally, the industry has struggled with fragmented tools, limited model transparency, and insufficient transient performance evaluation. However, this platform effectively addresses these challenges. By offering a unified and transparent workflow, it ensures seamless integration across all design stages. Moreover, it enhances efficiency and usability, reinforcing its value as an IVT design platform. As a result, engineers can perform more reliable and accurate performance analyses while overcoming common barriers in the field.
Modular Architecture for Comprehensive Instrument Transformer Design
Furthermore, the platform has been developed in collaboration with a leading manufacturer, resulting in a modular and adaptable architecture. Because of this flexibility, it can be extended to support the design and performance assessment of a wide range of instrument transformers, including Capacitive Voltage Transformers (CVTs), Inductive Voltage Transformers (IVTs), and Current Transformers (CTs). Additionally, the design methodology can incorporate specific requirements from other manufacturers through ongoing collaboration. Consequently, the platform continues to evolve, ensuring it meets diverse and changing design needs while maintaining its effectiveness as an IVT design platform.
