Description

The SIPROTEC 7UT85 transformer differential protection device is designed specifically for the protection of two-winding transformers (2 sides). 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 short cables lines, reactance coil (shunt reactors)). With its modular structure, flexibility, and the high-performance DIGSI 5 engineering tool, SIPROTEC 7UT85 offers future-oriented solutions for protection, control, automation, monitoring, and Power Quality - Basic.

Functions

With the Disconnection of measuring points function, you can disconnect the 1-3ph measuring point from a protection function group. If the measuring point has been disconnected, you can perform any work without influencing the work of the protection functions that have been assigned to the measuring point. After disconnection of the measuring point, the differential protection, for example, stops taking the measured values of this measuring point into account for calculating the differential current. DIGSI 5 permits all functions to be configured and combined as required.
