Functional Description
IS200EACFG1BAA is an Exciter AC Feedback Board developed by GE. It is a part of the EX2100 control system. The Exciter Ac Feedback board (EACF) serves the crucial function of measuring the exciter PPT ac supply voltage and current. Positioned within the exciter auxiliary cabinet, this terminal board is integral to ensuring optimal excitation control system performance.
Features
- Board Components and Features: The terminal board comprises transformers designed for three-phase voltage measurement and accommodates terminals for two Flux/Air core coils. These components facilitate accurate and reliable measurement of exciter parameters critical for system operation.
- Output Configuration: The outputs from the voltage and current circuits are distributed across three DB9 connectors, enabling convenient cable connections to controllers M1, M2, and C. This layout facilitates efficient communication and data transmission between the board and the corresponding control units.
- Cabling Considerations: To ensure seamless integration, the cable between the board and the EBKP backplane board can extend up to 90 meters in length. This generous allowance accommodates varying installation configurations and system setups.
- Board Variants: The board is available in two versions: EACFG1 for inputs up to 480 V rms and EACFG2 for inputs up to 1000 V rms. These variants cater to different voltage requirements, providing flexibility and compatibility with diverse exciter systems.
- Noise Suppression and Shielding: To mitigate high-frequency noise interference, the board incorporates high-frequency noise suppression near the point of signal entry. Additionally, cable shield terminal screws, connected to chassis ground, are strategically positioned within close proximity to the input screws, ensuring effective shielding and minimizing signal distortion.
Application Data
- The Exciter Ac Feedback board (EACF) serves the critical function of monitoring the exciter PPT AC supply voltage and current. Located within the exciter auxiliary cabinet, this terminal board is equipped with transformers for three-phase voltage measurement and provisions for two Flux/Air core coils. The outputs from the voltage and current measurement circuits are dispersed to three DB9 connectors, facilitating cable connections to controllers M1, M2, and C. Notably, the cable length between the EACF and the EBKP backplane board can extend up to 90 meters, offering flexibility in system configuration and placement.
- The board is available in two versions: EACFG1, designed for inputs up to 480 V rms, and EACFG2, accommodating inputs up to 1000 V rms. This distinction allows for compatibility with various excitation system requirements, ensuring optimal performance across different voltage ranges.
- To mitigate high-frequency noise interference, the board features noise suppression mechanisms near the signal entry points, particularly for the Flux/Air core input signals. Additionally, cable shield terminal screws are strategically positioned within three inches of the input screws, where applicable, providing efficient grounding and shielding against external electromagnetic disturbances.
- The layout of the board is depicted in the accompanying figure. Key components include T1 through T4, which represent the three-phase voltage transformers, and individual screw connectors TB1, TB2, and TB3 designated for the voltage inputs. Terminal block TB4 serves as the interface for wiring from the two Flux/Air core coils. Moreover, three 9-pin sub-D connectors, labeled J504, J509, and J514, facilitate cable connections to the EBKP backplane, enabling seamless integration with EMIO boards for comprehensive system functionality and monitoring.
