Working Principle
The ICRM-15 monitors generator terminal voltage and compares it with a reference setpoint. If the voltage deviates due to load changes, speed variation, or system disturbance, the regulator adjusts the excitation signal to the generator field or exciter. Increasing excitation raises generator voltage, while reducing excitation lowers it. This closed-loop control maintains stable output voltage and helps the generator respond smoothly to changing operating conditions. The module may also support protection functions such as overvoltage, undervoltage, or excitation limits depending on system design.
Installation Requirements
- Verify generator type, voltage rating, and excitation system before installation.
- Confirm the ICRM-15 nameplate ratings match the application.
- De-energize the generator control circuit before wiring.
- Connect voltage sensing inputs according to the Basler Electric wiring diagram.
- Verify exciter or field output connections before commissioning.
- Ensure proper grounding and shielding for sensing circuits.
- Check ventilation and temperature conditions in the control cabinet.
- Perform no-load and loaded voltage regulation tests after installation.
Precautions for Use
- Do not exceed the rated input voltage, output current, or temperature limits.
- Do not adjust AVR settings without qualified supervision.
- Verify generator rotation, voltage, and frequency before enabling regulation.
- Avoid loose connections in voltage sensing and excitation circuits.
- Do not operate the generator with damaged sensing or excitation wiring.
- Keep configuration records before replacing the module.
- Replace failed units with the same Basler Electric model and revision.
- Only qualified generator or power system engineers should install or commission the device.
- Refer to the official Basler Electric documentation for exact ratings, wiring, and adjustment procedures.
