Ground Detection System Architecture

• EXAM works with EGDM to detect field ground faults. Protects generator shaft from damaging ground currents.
• Drives low-frequency AC voltage into field winding center. Creates measurable current path relative to ground.
• Attenuates high-voltage bridge signals to usable levels. Scales field bus voltage for EGDM processing.
• Single IS200EXAMG1BAA required per system. Works in simplex and triple modular redundant configurations.
• Interfaces with EROC instead of EGDM in certain EX2100 versions. Provides equivalent ground detection functionality.
• Also utilized in standalone PGDM simplex ground detector. Works with BGTB, BFGD, and BPPB boards.

Connector and Interface Design

• J1: Three-pin locking female connector. Connects to field flashing relay auxiliary contact cable.
• J2: Nine-pin female D-sub connector labeled Ground Detector. Handles test signal transmission, relay control, and leakage current monitoring.
• E1 and E2 stab-on connectors. Establish connection between field bus voltages (Vbus-p and Vbus-n) and attenuator module.
• TB1 screw terminal. Links EXAM board shield ground to cabinet chassis ground for electrical safety.
• Interconnection via Exciter Power Backplane (EPBP). Single 9-pin cable connects EXAM to EPBP for seamless communication.

Configuration and Adjustment Controls

• JP1, JP2, JP3 adjustable jumpers. Configure module for various potential transformer secondary voltages.
• Jumper settings ensure compatibility with different power supply setups. Optimizes performance based on specific voltage requirements.
• No testpoints, fuses, or LED indicators present. Design focuses on essential connectivity and configuration elements.
• Three jumper switches enable field customization. Accommodates diverse PPT secondary voltage applications.

Onboard Component Inventory

• Two metal oxide varistors. Provide transient voltage suppression for field bus inputs.
• One relay. Supports ground detection switching and fault signaling.
• Four large polyester-vinyl capacitors. Store energy and filter AC signals.
• Twenty wire-wound resistors. Handle power dissipation and signal attenuation.
• Female 3-position plug and female 9-position cable connector. Durable locking mechanisms for secure field wiring.

System Integration and Compatibility

• Mounts within High Voltage Interface module in auxiliary cabinet. Optimal placement for field voltage attenuation.
• Consistent interconnection across all system configurations. Simplifies integration and troubleshooting processes.
• DSPX Digital Signal Processor Control Board provides computational power. Ensures robust ground detection performance.
• IS200 series tag confirms Mark VI assembly and USA manufacture. Dual-functional series indicates domestic original production.
• EXAM functional abbreviation clearly identifies board purpose. Standardized across EX2100e excitation platforms.

Frequently Asked Questions

Q: What is the difference between IS200EXAMG1BAA and earlier EXAM revisions?
A: BAA is the third revision with enhanced component selection and normal PCB coating. Fully backward compatible with first two revisions.

Q: Can I use this board in EX2100 non-e systems?
A: Yes. IS200EXAMG1BAA operates in both EX2100 and EX2100e platforms. Mounting and interconnection remain identical.

Q: How many EXAM boards do I need for a TMR configuration?
A: Only one. Unlike I/O packs, ground detection requires single IS200EXAMG1BAA regardless of simplex or TMR system architecture.

Q: What do the JP1, JP2, and JP3 jumpers configure?
A: These jumpers match the module to different potential transformer secondary voltages. Set according to your specific PT application.

Q: Why are there no status LEDs on this board?
A: EXAM is a passive attenuation and coupling module. Ground detection status is monitored through EGDM or EROC indicators.

Q: What is the typical lead time for IS200EXAMG1BAA?
A: In-stock orders ship within 48 hours. Volume orders typically ship within 5 business days.
