SIPROTEC 7UT86 Transformer Protection
- Артикул:
- 7UT86
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 protected downstream objects (such as cables or lines). In this regard 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 futureoriented system solutions with high investment security and low operating costs.
