Wiring Schematic Notes
Ensure correct phase alignment when wiring sensing inputs to the Automatic Voltage Regulator (AVR). Cross-phase connections will result in over-excitation and system tripping.
- Verify main field resistance prior to energizing static exciter units.
- Ensure rotating rectifier diodes are tested for forward and reverse bias integrity.
- Maintain minimum 10 AWG shielded wiring for analog voltage sensing lines.
