Functional Description
IS200EXAMG1BAA is an Exciter Attenuation Module developed by GE. It is a part of EX2100e excitation system. The Exciter Attenuation Module (EXAM) is an integral component of the ground detection system for the EX2100 Excitation Control system. The component offers robust connectivity and configuration options essential for its effective operation within the system, ensuring reliable performance and compatibility
Features
- Ground Detection: Combined with the Exciter Ground Detector Module (EGDM), the EXAM detects ground faults within the system.
- Attenuation: It attenuates signals between the field bus and the EGDM, scaling high voltage from the bridge to a usable level.
- Mounting: The EXAM is installed within the High Voltage Interface (HVI) module situated in the auxiliary cabinet.
- Location: Its placement in the HVI module ensures optimal functionality within the system.
- Interconnection: The EXAM and EGDM(s) are linked via the Exciter Power Backplane (EPBP), facilitating seamless communication.
- Cabling: A single 9-pin cable establishes the connection between the EXAM and the EPBP, ensuring efficient data transmission.
- Simplicity and Redundancy: Regardless of the system configuration (simplex or triple modular redundant), only one EXAM is necessary, streamlining installation and maintenance.
- Consistency in Interconnection: The interconnection remains consistent across different configurations, simplifying integration and troubleshooting processes.
Integration Options
- Exciter/Regulator Interface: In certain EX2100 versions, the EXAM interfaces with the Exciter/Regulator Options Board (EROC) instead of the EGDM, providing equivalent ground detection functionality.
- Exciter Ground Detector Module (EGDM): The Exciter Ground Detector Module (EGDM) collaborates with the EXAM to enhance ground detection capabilities within the EX2100
- Excitation Control system.
- Computational Power: The Digital Signal Processor Control Board (DSPX) furnishes computational capabilities for the ground detection system, ensuring robust performance.
- PGDM: The EXAM is also utilized in a standalone simplex ground detector product known as PGDM.
Integration Components: Interface boards (BGTB and BFGD) and the processor board (BPPB) complement the EXAM in PGDM, offering similar functionality to EX2100-based boards.
Application Data
- Connectors:
- Connector J2: This is a 9-pin D connector used for test signal transmission, relay control, and monitoring leakage current.
- Connector J1: This is a three-pin locking connector that connects to the cable leading to the field flashing relay auxiliary contact, enabling communication and coordination with external components.
- Stab-on Connectors:
