 8807-51 MEMORY HiCORDER
|
| Overview |
| Instantaneous Analysis and Long-term Recording of Harmonic Waves for Maintenance of Commercial Power Systems
|
- Measure harmonics up to 40 orders from the fundamental wave
- Analysis display includes RMS value, content factor, phase angle, active power, and power phase angle for each order of harmonics (numeric and graphic display)
- Analysis display of total RMS value, total deitortion, active/ reactive/ apparent power, and power factor (numeric display)
- Bar graph and numeric data display
- Power phase angle can be displayed as a vector
