iPOWER SPECIAL AND CUSTOMIZED TRANSFORMERS
iPOWER’s special and customized transformers are expertly crafted to meet specific power needs, delivering high performance and flexibility in diverse environments. These transformers are designed with advanced customization options to suit unique applications, ensuring efficient energy distribution across various industries. Built with precision and durability, they offer tailored solutions for complex power challenges.
Converter Transformers
These transformers are used to supply variable speed drives (VSD) for motor control. A VSD typically injects a whole spectrum of harmonics into the supply lines, and the transformer design needs to accommodate these harmonics. A converter transformer is typically rated at 100% capacity, while a distribution transformer is typically rated at 80% capacity. VSD drives are based on power electronics and usually require a neutral line; hence, the most common vector group is DYn11, i.e., a delta primary with a star secondary with the neutral point brought out.
Furnace Transformers
The smelting industry uses AC & DC processes depending on the arc furnace application. DC Electric Arc Furnace (EAF) Transformers are similar in design to rectifier transformers but have many more taps and on-load tap changers. AC (EAF) transformers are subjected to repeat short circuit conditions that require a more conservative design. They too have many taps and on-load tap changers. The AC (EAF) transformers are generally manufactured as single-phase units, which allow the furnace design and process to be optimized.
Rectifiers Transformers
These transformers cover a large range of configurations. The IEC60076 standards list 19 configurations; most of the configurations were developed in the era of Mercury-arc rectifiers and have less relevance since the development of high-current thyristors (silicon-controlled rectifiers) and more advanced devices such as GTOs & IGCTs. The two commonly used rectifiers are the three-phase bridge rectifier and the six-phase double star with inter-phase transformer (IPT), which requires a dual secondary winding transformer design. The normal bridge rectifier uses a normal 3-phase design. We offer extended delta, phase shifted transformers where impedance and voltage matching are critical in a twelve-pulse plant.
