Description SIPROTEC 7UT82 - Transformer Protection

Transformer protection for two winding transformers up to 2 sides and 2 measurement points

The transformer differential protection SIPROTEC 7UT82 is a universal protection, control and automation device on the basis of the SIPROTEC 5 system. It is especially designed for the protection 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 protected downstream objects (e.g. cables, line). The device supports all SIPROTEC 5 system characteristics. It enables future-oriented system solutions with high investment security and low operating costs.
