الوصف

The GE part number IS200EXAMG1B is an Exciter Attenuation Module for the EX2100 Excitation Control System. Its primary function is to safely reduce high-voltage signals from the generator’s field and exciter circuits to a low-voltage level that can be measured by the sensitive control and feedback cards of the EX2100 system. ⚡

 

Function and Key Features

 

A generator’s excitation system operates at high voltages and currents. The main control cards, however, require low-voltage signals (typically in the range of 0-10V) for accurate measurement and processing. The EXAM board bridges this gap.

  • Signal Attenuation: The board uses a network of resistors and transformers to safely “step down” the high-voltage AC and DC signals from the generator and exciter. This process is called attenuation.
  • Electrical Isolation: The board also provides critical electrical isolation between the high-power exciter circuits and the sensitive, low-voltage control electronics. This protects the control system from damaging voltage spikes and electrical noise.
  • System Integration: The EXAM board is an essential part of the system’s feedback loop. It works in conjunction with the feedback cards (like the EDFF or EDIF) to provide the main processor with accurate, real-time measurements of the exciter’s output.
  • Robust Design: Like all GE industrial control components, it’s built to withstand the harsh conditions of a power plant.
