    Product Overview

    Meta-Power Solutions’ substation transformers are critical components in power networks. Their durability and availability have a significant impact on grid reliability and performance. MPS does not compromise on quality. Each unit we deliver undergoes rigorous full-acceptance testing.

    MPS offers a comprehensive line of substation transformers and associated components. Our entire range results from our unique research, development, and manufacturing, making us exceptional in the industry. As a result, we have gained extensive experience in every aspect of power transformer technology. Customers can count on our products’ quality and reliability.

    MPS substation transformers provide high levels of customization and can be used in a variety of applications. With voltage up to 138 kV and rated power up to 200 MVA, they are appropriate for a variety of harsh environments. Furthermore, the entire range complies with the latest global and regional eco-efficiency standards.

    Applications

    Liquid-filled substation transformers are used in a wide range of industrial and commercial applications. Each unit is manufactured in compliance with IEEE, ANSI, and NEMA standards. The transformers are available with three different fluids: mineral oil, silicone transformer oil, or less flammable seed oil. In general, substation transformers are equipped with either on-load or off-load tap-changers.

    Transformer Features

    This three-phase substation transformer comes with a power rating of 76 MVA and a voltage rating of 115 KV (Wye) / 35 KV (Delta). This unit’s cores are made from Grain Oriented Silicon Steel using state-of-the-art technology.

    This three-phase transformer is highly energy efficient with lower heat emissions, resulting in fewer cooling requirements. The unit also features mineral oil as an insulating fluid with a 65°C temperature rise.
