The GE part number IS200JGPAG1A is a Mark VIe Ground Terminal Board. Its primary function is to provide a centralized and secure termination point for grounding and shield wires within the Mark VIe Excitation Control System. ⚡
Function and Key Features
This board is a passive but crucial component of the system’s wiring and safety infrastructure. Proper grounding is essential in industrial environments to protect against electrical noise and faults.
-
- Grounding Point: The JGPA board offers a dedicated set of terminals for connecting the chassis ground, instrument ground, and cable shield grounds. This design ensures all components are at the same electrical potential, preventing ground loops that can introduce noise and errors into the system’s signals.
- Noise Immunity: By providing a clean ground path, the board helps to isolate the sensitive electronics of the Mark VIe from electromagnetic interference (EMI) and radio frequency interference (RFI) common in power plants.
- Safety: It ensures a safe path for fault currents, which is critical for protecting both personnel and equipment in the event of an electrical fault.
- System Integration: The JGPA board is typically mounted in the control cabinet and is part of the system’s overall wiring and safety infrastructure.
- Robust Design: Like all GE industrial control components, it is built to withstand the harsh conditions of a power plant.
Applications
The IS200JGPAG1A is a key component in power generation facilities that have upgraded to the Mark VIe Excitation Control System. It is essential for:
- System Reliability: A stable, low-noise ground path is vital for the reliable operation of the control system’s electronics.
- Fault Protection: It is a critical part of the system’s fault protection scheme, helping to safely dissipate fault currents and prevent damage.
