Large power transformers are in the power range above 250 MVA, generator and network intertie transformers with off-load or on-load tap changers, or a combination of both, are recommended. Depending on the on-site requirements, they can be designed as multiwinding transformers or autotransformers, in 3-phase or 1-phase versions. Even with ratings of more than 1,000 MVA and voltages up to 1,200 kV (800 kV), the feasibility limits have not yet been reached. We manufacture these units according to IEC 60076 as well as other international and national standards (e.g., ANSI/IEEE). Generator step-up (GSU) transformers GSU units transform the voltage up from the generator voltage level to the transmission voltage level, which may be as high as 1,200 kV system voltage. Such transformers are usually YNd-connected. In order to make an inquiry regarding a GSU power transformer, the technical data for the items in this section are required. Step-down transformers Step-down transformers transform the voltage down from the transmission voltage level to an appropriate distribution voltage level. The power rating of step-down transformers may range up to the power rating of the transmission line. System interconnecting transformers System interconnecting transformers connect transmission systems with different voltages together so that active as well as reactive power can be exchanged between the systems. Bringing the energy safely to the consumer: A basic requirement applicable to all Power Transformers. However, every single one is unique designed according to individual factors such as voltage, power, climate, system topography, sound level and many more. Tinde Power is your partner, who picks up these requirements converting them into convincing solutions with maximum quality. Power Transformers that render their service reliably at site.

Large power transformers rated above 250 MVA are critical components in power generation and grid infrastructure. These generator step-up (GSU) and network intertie transformers typically operate at voltages ranging from 110kV to 765kV, featuring either off-load or on-load tap changers for voltage regulation. As heavy industrial capital equipment, they are shipped internationally via flat-rack containers or breakbulk vessels, making them a significant category in global electrical equipment trade.
