This voltage attenuator board functions as a signal conditioning component within GE Mark V turbine control systems. It scales high-voltage input signals down to levels suitable for analog-to-digital conversion. The board ensures accurate measurement of AC voltage signals from generators and power distribution equipment. Its robust design meets the demanding requirements of turbine-generator monitoring applications.
Signal Conditioning and Voltage Scaling
The GE DS200SVAAG1A receives AC voltage inputs from the generator terminals or busbars and scales them appropriately. It then passes these conditioned signals to the DS200ADCI** analog input board for further processing. The board handles multiple AC voltage channels simultaneously, enabling comprehensive power system monitoring. This module incorporates precision resistors and isolation amplifiers to maintain accuracy and safety. It also provides electrical isolation between the high-voltage side and the control electronics.
