GE’s D25 is a flexible, modular, and upgradable automation controller, suitable for both large and small substation automation projects in either new or retrofit situations. The D25 provides the tools and flexibility necessary to create customized automation and control applications including; communications & data concentrator, automation controller, metering & sequence of events fault recording, and transformer monitoring & control. The D25 controller replaces multiple devices with a single unit. Unified design reduces wiring and maintenance costs. The D25 controller retrieves data from legacy and third-party devices such as relays, transfers it to a host or enterprise system, monitors and runs diagnostics of primary equipment and expands to meet future physical and functional station requirements. D25 has the option of being equipped with two different built-in screens. First option is a Data Display Panel to show status of different points (digital or analog) to the operator. The second option is a Graphical Display Panel (GDP) which is a touch screen monochrome LCD allowing users to configure dynamic displays with one-line diagrams and alarm screens. Local control is also supported with the GDP option making the GDP a fully-fledged local HMI. The D25 measures and records total harmonic distortion, harmonic spectrum (DC to 21st harmonic), RMS trending, RMS profiling, voltage sags, swells and interruptions, allowing operators and analysts to examine the consistency of power going through the system and pinpoint problem area. Fault records can be transferred automatically via a LAN to the substation computer or directly to a remote PC via email.
