GE IS200JGNDG1A MKVIe, Ground Terminal Board

The GE part number IS200JGNDG1A is a Ground Terminal Board for the Mark VIe Excitation Control System. Its primary function is to provide a dedicated, centralized and secure connection point for all the grounding and shielding wires in the system. ⚡

Function and Key Features

Proper grounding is critically important in industrial control systems to protect against electrical noise, voltage transients, and faults. The JGND board is specifically designed to manage these connections.

• • Grounding Point: The board provides a set of terminals for connecting the chassis ground, instrument ground, and other ground wires. This ensures that all components in the system are at the same electrical potential, preventing ground loops.
  • Noise Immunity: By providing a dedicated and clean ground path, the board helps to isolate the sensitive electronics of the Mark VIe from electromagnetic interference (EMI) and radio frequency interference (RFI) that are common in a power plant environment.
  • Safety: It ensures a safe path for fault currents, which helps to protect both personnel and equipment in the event of a ground fault.

• System Integration: The JGND board is typically mounted in the control cabinet and is a critical 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 IS200JGNDG1A is a key component in power generation facilities that have upgraded to the Mark VIe Excitation Control System. It is essential for:

• System Reliability: By providing a stable and noise-free ground, it ensures 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.
