Deskripsi
Overview
The GE D25 is a multifunctional Intelligent Electronic Device (IED) and substation automation controller. It consolidates multiple roles—including PLC, RTU, data concentrator, bay controller, and power quality monitor—into a single, modular unit. Designed for both new installations and retrofit projects, the D25 enables streamlined substation monitoring, control, and automation with a single platform. Its rugged design ensures reliable operation under harsh electrical environments.
Applications
-
Substation automation and control for utilities and industrial power systems.
-
Monitoring and management of legacy relays and third-party devices.
-
Data acquisition, fault recording, power quality analysis, and local HMI operation.
-
Software-based automation schemes via LogicLinx® soft logic.

Considerations / FAQ
Q: Is the D25 still in production?
A: Manufacturing for the D25 has been discontinued. Alternative models include:
-
For bay control: C30 or C60
-
For gateway applications: G100
-
For RTU: G100 combined with D20.IO or C30/C60
Q: Can the D25 function as a protective relay?
A: The D25 is designed for automation, monitoring, and control, not for direct protective relay functions.
Q: How does the local HMI function?
A: The GDP option allows touch screen operation, dynamic display of alarms, and full local control, while the Data Display Panel provides basic status readouts.
Q: How is power quality monitored?
A: The D25 records harmonics (DC–21st), RMS trends, sags, swells, and interruptions, providing detailed data for diagnostics and energy quality analysis.
Q: Can it replace multiple devices?
A: Yes, it consolidates PLC, RTU, bay controller, gateway, metering, and monitoring into one unit, reducing wiring, footprint, and maintenance costs.
