الوصف

The GE part number IS200EBACG1A is an EX2100E Bridge AC Feedback Board. It’s a key component of GE’s Mark VIe Excitation Control Systems. Its primary function is to measure the AC voltage and current coming from the rectifier bridges that supply power to the generator’s field, which is crucial for the control and protection of the excitation system. This particular version is rated for systems up to 1400V. ⚡️

 

Function and Key Features

 

A generator’s excitation system uses a rectifier bridge to convert AC power into the DC power needed for the generator’s field windings. This board is designed to monitor that power.

  • Bridge AC Feedback: The board gets its name from its function of measuring the AC input to the thyristor or diode bridges. This feedback is essential for the EX2100E control system to manage the firing of the thyristors and to ensure the proper amount of DC power is being supplied to the generator’s field.
  • Voltage Rating (1400V): The “1400V” designation indicates that this board is specifically configured for applications with a nominal AC supply voltage of up to 1400 Volts. This high voltage rating is common in power generation systems.
  • System Integration: The EBAC board works in conjunction with the main control card (like a DSPX) and other I/O boards to form the complete excitation control system.
  • Robust Design: Like all GE industrial control components, it’s built to withstand the harsh conditions of a power plant, including high voltages, vibrations, and electromagnetic interference.
