Hitachi Molded Transformer with Built-in Protection Circuit TVP Vacuum circuit breakers and gas circuit breakers used in power receiving and transforming equipment have excellent arc-extinguishing performance during switching operations; however, depending on the switching conditions, surges (overvoltages) may occur, posing a risk of damage to the transformer. Current large-scale data centers require very high redundancy, and once downtime occurs, it can lead to enormous losses, making surge protection for transformers a critical issue. The Hitachi Molded Transformer TVP, equipped with a built-in protection circuit, suppresses the switching surges from circuit breakers that flow into the transformer, contributing to the stable operation of large-scale data centers.

Amorphous Transformers for Solar Power Generation Electricity generated by solar panels cannot be sold 100%. It is lost as waste while connected to the grid. Additionally, during non-generating hours (at night), electricity is purchased due to standby power and other factors. Hitachi's solar-specific amorphous transformer, Super Amorphous Zero CE, significantly reduces power loss during electricity sales with ultra-high efficiency. Furthermore, by minimizing the transformer's standby power (no-load loss) to the extreme, it contributes to improving overall business profitability in the power generation sector. Multi-winding Transformers for Solar Power Generation By connecting multiple power conditioners (PCS) to a single transformer, not only does the installation space for the transformer become compact, but the burden of wiring materials and grid-side equipment is also reduced, allowing for a shorter construction period. Hitachi Industrial Systems' transformers for solar power generation can connect up to three PCS. For more details, please contact us.
