⚡ Excitation & Voltage Regulation
The SSR 32-12 controls the generator excitation field to maintain the desired AC generator output voltage. Basler documentation specifies a regulation accuracy of approximately ±0.25% from no-load to full-rated load, with thermal stability of approximately ±0.5% for a 50°C temperature change within the operating range.
The regulator provides internal voltage adjustment and supports external voltage adjustment. Voltage sensing taps are available for common generator voltage levels, including 120, 240, 480, and 600 VAC configurations.
The unit can also provide reactive droop compensation for parallel generator operation when correctly configured with the appropriate current-transformer sensing circuit.
🔌 Electrical & Protection Functions
The SSR 32-12 includes several functions intended to support stable generator excitation:
- Voltage regulation — maintains generator terminal voltage.
- Frequency compensation — supports V/Hz or 2 V/Hz characteristics.
- Underfrequency protection — reduces excitation response when generator frequency falls below the selected threshold.
- Overexcitation protection — removes excitation when specified forcing conditions persist.
- Voltage buildup — supports buildup from residual generator voltage.
- Reactive droop compensation — assists reactive load sharing between paralleled generators.
- Stability adjustment — allows response characteristics to be adjusted for generator behavior.
- Unit/Parallel operation — supports generator operation either independently or in parallel.
