Transformer differential protection
SIPROTEC 7UT82, SIPROTEC 7UT85, SIPROTEC 7UT86 and SIPROTEC 7UT87
The SIPROTEC 7UT82/85/86/87 transformer differential protection have been designed specifically for the protection of two and multi-winding (up to 5 sides). transformers. They are the main protection for the transformer and contain 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). The modular expandability of the hardware supports you in this process. With their modular structure, flexibility, and the high-performance DIGSI 5 engineering tool, SIPROTEC 5 devices offer future-oriented system solutions with high investment security and low operating costs.
