en.Wedoany.com Reported - Tecnalia is advancing the validation of iTrafos smart distribution transformers through its testing infrastructure. These transformers can dynamically adjust voltage in real time, becoming a key technology for managing decentralized power grids with a high share of renewable energy. Manufacturers can use this facility for prototype evaluation to accelerate time-to-market.
The core innovation of iTrafos lies in the integration of an On-Load Tap Changer (OLTC), which can change the transformer ratio without interrupting power supply. Unlike conventional transformers, this system can adjust the output voltage during operation. This capability enables greater flexibility in grid management, particularly in applications with high penetration of renewable energy sources such as photovoltaics, where voltage fluctuations are frequent.
The main operational advantages of iTrafos include optimizing energy efficiency by reducing losses, enhancing grid stability against voltage fluctuations, and improving power quality for end users. However, the implementation of the on-load tap changer increases mechanical and electrical complexity. The movement of contacts under load generates arcing and thermal stress, which must be precisely managed to avoid serious failures. Therefore, a comprehensive validation and verification process from design to commercial deployment is required to ensure the safety and service life of the equipment under real stress conditions.
In this context of technological development, Tecnalia serves as a reference center for performing critical tests to evaluate the electromechanical behavior and electrical performance of iTrafos. These tests are essential for equipment certification and compliance, providing manufacturers with the foundational data needed to optimize their designs.
