Specialty Testers: SPD480: Phase Rotation Indicator
The SPD480 determines phase rotations on secondary potential transformers
- Easy to operate - connect one lead to each phase.
- Large alligator clips for easy connection to cables and bus bars.
- Operates properly on variable frequency drives. Does not give false readings by pulsed waveforms.
- Verify proper rotation on feeder extensions.
- Determine phase rotation on secondary potential transformers.
