The GE DS200SVIAG1A Shunt Isolator Board is a printed circuit board () manufactured by General Electric for use in their Mark V Speedtronic Gas/Steam Turbine Control Systems and their .
Its primary function is to provide electrical isolation and signal conditioning for current measurement signals derived from shunts in a high-voltage or high-current circuit.
Key Functions and Features
The () board is critical for safely and accurately monitoring electrical current in the drive or power sections of the turbine control system.
1. Current Measurement and Signal Conditioning
- Shunt Voltage Measurement: Current in a high-power circuit is typically measured using a shunt resistor, a low-resistance component placed in series with the load. The voltage drop across this shunt is proportional to the current flowing through it ().
- Isolation: The measures this small voltage from the high-power shunt and electrically isolates the measurement signal from the rest of the sensitive control circuitry. This is crucial for:
- Safety: Protecting the low-voltage electronics in the Mark V system from the high voltages present in the power circuit.
- Accuracy: Preventing electrical noise and ground loop interference from affecting the analog signals.
- Signal Scaling: It contains precision amplifiers and circuitry to scale and condition the shunt signal before it is sent to the main control processor for use in control loops and protection functions.
2. Technical Specifications
While specific technical manuals are required for full details, common specifications associated with this board include:
- System Series: series for the GE Mark V Speedtronic Turbine Control System.
- Product Type: Shunt Isolator Board.
- Number of Channels: Typically supports multiple channels for current measurement (e.g., 12 channels are sometimes cited).
- Interface: Features multiple terminal blocks for connecting the shunt wiring, as well as test points, jumpers, and a status for diagnostics.
- Operating Conditions: Designed for robust industrial environments with an operating temperature range generally around to .
The is an older, legacy component, often replaced or repaired to maintain the operational reliability of the classic GE Mark V turbine installations.
