Phase-shifting transformers (PSTs), often called Quadrature Boosters, are critical for managing active power flow in complex transmission networks. By adjusting the phase angle between input and output, PSTs prevent line overloading and optimize grid utilization.
In cross-border energy trading, PSTs allow grid operators to control "loop flows," ensuring that power travels along contracted paths rather than through parallel, lower-impedance networks that may lack capacity.
Our PST designs mitigate voltage fluctuations and improve transient stability, making them indispensable for integrating volatile renewable energy sources like wind and solar farms into the main grid.
Global EPC contractors and utilities are prioritizing Total Cost of Ownership (TCO) over initial purchase price. This includes evaluating factory testing capabilities, lead time reliability, and after-sales field service support. Henan Pirooz Power addresses these needs with comprehensive FAT (Factory Acceptance Testing) and onsite technical guidance.
Leveraging advanced manufacturing technologies, China has become the global hub for transformer production, offering an unparalleled balance of scale, precision, and cost-efficiency.
Implementing on-load tap-changing transformers to manage heavy load fluctuations in manufacturing zones, ensuring zero downtime for precision machinery.
Using rectifier and step-up transformers for large-scale solar farms and wind parks to efficiently transport energy to the high-voltage national grid.
Deploying compact European and American-style substations in high-density residential areas, providing safe and aesthetically integrated power distribution.
Henan Pirooz Power's core product range includes 10kV–35kV oil-immersed power transformers (S11, S13, S14, and S20 series), dry-type transformers (SCB10, SCB11, SCB13, and SCBH15 series), as well as on-load tap-changing transformers, rectifier transformers, and furnace transformers designed for specialized industrial applications. Our integrated solutions are widely applied in power grid construction, industrial manufacturing, mining, metallurgy, petrochemicals, transportation systems, and renewable energy projects.
A1: PSTs allow for the active control of real power flow through a transmission line. By adjusting the phase angle, operators can redirect power from overloaded lines to underutilized ones, improving overall grid reliability and efficiency.
A2: We implement a rigorous QC protocol using automated testing equipment. Every unit undergoes routine tests including insulation resistance, turn ratio, winding resistance, and dielectric tests. We also provide Type Test reports upon request to ensure compliance with IEC/ANSI standards.
A3: Yes. We specialize in bespoke engineering. Whether you need 60Hz for the American market or specific vector groups (e.g., Dyn11, Yyn0), our R&D team can design a solution that fits your local grid requirements perfectly.
A4: Amorphous alloy cores have much lower magnetic hysteresis loss compared to traditional silicon steel. This results in significantly lower no-load losses, making them ideal for utilities focused on reducing carbon footprints and operational costs.
A5: Thanks to our Factory 4.0 infrastructure and lean manufacturing, we typically offer lead times of 4-8 weeks depending on the complexity and customization level, which is significantly faster than the global average.
Looking ahead, Henan Pirooz Power Co., Ltd. is committed to innovation, energy efficiency, and smart manufacturing development. By continuously improving product performance and system integration capabilities, we aim to become a globally recognized provider of advanced power equipment solutions, supporting the development of modern and sustainable energy infrastructure.
