FUNCTIONAL DESCRIPTION:
IS200VATFG1A is a Voltage Attenuator Feedback Board manufactured and designed by General Electric as part of the Mark VI Series used in GE Speedtronic Turbine Control Systems. The Voltage Attenuator Feedback Board in this context serves to attenuate or adjust the voltage of input signals within the control system while providing feedback to maintain stability and accuracy. This board typically employs a combination of resistors, capacitors, and operational amplifiers to achieve the desired voltage attenuation ratio and ensure that the output voltage remains consistent with the input signal. The board provides the control with a direct measurement of the DC bus neutral voltage. This signal is then monitored after being filtered and conditioned to remove the effects of bridge modulation. The voltage will be nearly zero if there is no motor ground fault condition. When there is a fault in the ground, the voltage is at its peak. The voltage increases almost linearly between zero and the maximum voltage in the case of a partial ground fault, which could be caused by damaged motor insulation. The ground fault voltage, variable Gnd cur signal is compared to thresholds to create the alarm or trip fault.
FEATURES:
Precision Voltage Attenuation: The board is designed to accurately attenuate the input voltage signals to desired levels, allowing for precise control over voltage levels within the system.
Feedback Mechanism: It integrates a feedback mechanism to constantly monitor the output voltage and adjust the attenuation ratio as needed to maintain stability and accuracy in voltage regulation.
Wide Operating Range: The board is capable of operating across a wide range of input voltage levels typically encountered in gas turbine control systems, ensuring compatibility with various operational conditions.
High Linearity: It maintains high linearity in voltage attenuation, minimizing distortion and ensuring faithful representation of the input signals across the attenuation range.
Low Noise: The board is engineered to minimize noise interference, ensuring clean and reliable voltage output signals essential for accurate control and monitoring within the gas turbine system.
Temperature Stability: It exhibits stability in performance over a range of temperatures commonly encountered in gas turbine environments, ensuring consistent operation even under varying thermal conditions.

How is the voltage signal monitored?
The voltage signal is filtered and conditioned to remove the effects of bridge modulation before being monitored.
What is the voltage level when there is no motor ground fault condition?
The voltage will be nearly zero when there is no motor ground fault condition.
What happens to the voltage level in case of a partial ground fault?
The voltage increases almost linearly between zero and the maximum voltage in the case of a partial ground fault, which could be caused by damaged motor insulation.
