What do you need to Measure?
The most commonly occurring behaviours that cause excessive losses and disturbances can be summed up as follows, to give an idea of where poor power quality arises:
- Reactive power
- Harmonics
- Network unbalance
- Transients (fast disturbances)
- Voltage variations (dips, sags, swells, brown-outs)
- Flicker
- Oscillations (resonances)
