## Smart Grid: Substation Automation Systems & IEC 61850

**[Substation](https://forumelectrical.com/substation-dc-system-testing-and-commissioning/)** Automation Systems (SAS) are widely used in modern power networks to improve power distribution reliability, efficiency and safety.

IEC 61850 is at the core of this digital evolution, an advanced worldwide standard that allows Intelligent Electronic Devices (IEDs) within a substation to communicate seamlessly.
