In the intricate dance of energy distribution, transformers play a pivotal role, seamlessly stepping up or down the voltage to ensure a smooth flow of electricity across power grids. However, this critical function exposes transformers to potential faults and anomalies that could jeopardize the entire power system. Enter the Siemens Siprotec 5 7UT87, a technological marvel designed to elevate transformer protection to new heights. This blog explores the intricate details of this advanced solution, delving into how it maximizes reliability by ensuring accurate and swift transformer differential protection.

Siemens Siprotec 5 7UT87: Importance of Transformer Differential Protection

Transformers with up to five windings are specifically protected by the SIPROTEC transformer differential protection 7UT87. Moreover, it should be applied in situations where a large number of measurement points—up to nine 3-phase current measuring points—are needed. Two parallel transformers can be protected simultaneously as an extra quick backup application. 

The primary protection for the transformer is provided by the SIPROTEC Transformer differential protection 7UT87, which also has numerous additional monitoring and protection features. For later protected objects (such as cables or lines), the extra protection features can also be utilized as a fallback. Future-oriented system solutions with high investment security and low running costs are provided by SIPROTEC Transformer differential protection 7UT87, thanks to its modular structure, adaptability, and the potent DIGSI 5 engineering tool.
