Product Overview
Key Features:
Direct Three-Phase Measurement: Directly measures three-phase machine voltage and current. This is fundamental for accurate control and monitoring of the generator or motor.
Single-Phase Measurement: Capable of performing single-phase measurements when required.
Auxiliary Inputs: Includes additional inputs, typically for sensing voltage and current from a tie line, providing more comprehensive system oversight.
Rotating Diode Monitoring: Specifically for indirect (brushless) excitation systems, it integrates a monitoring function for rotating diodes.
PT Monitoring Function: Includes a Potential Transformer (PT) monitoring function to ensure the integrity and accuracy of voltage measurements.
Benefits:
Enhanced System Stability: By incorporating a Power System Stabilizer (PSS), the MUB actively works to dampen power oscillations in the grid.
Optimized Performance and Efficiency: Accurate real-time measurements enable the excitation system to precisely control the generator's reactive power output and voltage.
Reliable Data for Diagnostics: The precise and continuous measurement of key electrical parameters provides valuable data for diagnostics, troubleshooting, and condition monitoring of the generator and its excitation system.
Simplified System Architecture and Maintenance: The MUB's function as an internal power supply for other control boards streamlines the overall system's power distribution.
