Product Code : Siprotec 7UT86
Brand Name : Siemens
Product Description

The SIPROTEC 7UT86 transformer differential protection has been designed specifically for the protection of three-winding transformers (3 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 cables or lines). In this process, you are also supported by the modular expandability of the hardware. The device supports all SIPROTEC 5 system characteristics. It enables upgradeable system solutions with high investment security and low operating costs. With its modular structure, flexibility and the powerful DIGSI 5 engineering tool, SIPROTEC 7UT86 offers future-oriented system solutions with high investment security and low operating costs.

Main function:

1 differential protection function (standard) with additional stabilization; up to 3 restricted ground-fault protection functions

For auto transformer applications 2 differential protection functions can be processed in an auto transformer function group.

Useable measuring points:

6 x 3-phase current measuring points, 4 x 1- phase current measuring points, 4 x 3-phase voltage measuring points; expandable to 4 sides

Inputs and outputs:

2 predefined standard variants with 12 current transformers 4 voltage transformers, 11 to
23 binary inputs, 18 to 34 binary outputs

Hardware flexibility:

Flexibly adjustable and expandable I/O quantity structure within the scope of the SIPROTEC 5 modular system.

Width of housing:

1/2 - 19 inches to 2/1 - 19 inches
