    The SIPROTEC 7UT82 transformer differential protection has been designed specifically for the protection of two-winding transformers. It is the main protection for the transformer and contains many other protection and monitoring functions. The additional protection functions can also be used as backup protection for subsequent protected objects (such as cables or lines). In this process, you are also supported by the modular expandability of the hardware. With its modular structure, flexi- bility and the powerful DIGSI 5 engineering tool, SIPROTEC 7UT82 offers future-oriented system solutions with high invest- ment security and low operating costs.
