3. What Is a D25* ?
Multifunction IED for transmission and distribution substations
Bay Level Controller for integrated substation control systems
Full advanced RTU functionality
Designed specifically for substation and distribution automation applications

4. Why the D25* Was Developed
Multiple functionality of devices being incorporated into a single component
Existing devices did not support variety and complexity of communication technologies now available (LAN)
Flexibility of applications
Ease of configuration and maintenance; both hardware and software
Interface to the new family of intelligent devices being deployed in substations (i.e. sensors)
Over 15,000 D25’s installed worldwide.
