Power Quality Study process:
Using a Fluke 434 Power Quality Analyzer Arc Flash Advisor Crews will:
- Visit the facility to attach a set of power monitoring CT’s and VT’s – This may require de-energising the test point.
- Provide Frontline Troubleshooting – Quickly diagnose problems and get your operations back online
Capture Power Quality Measures
- Magnitude – Long term level voltage
- Unbalance – Condition of the 3 phase power system and phase angle
- Harmonics – Peak and Total harmonic distortion
- Flicker – periodic fluctuation in voltage
Capture Transient Disturbances
- Dip (Sag) A momentary reduction in voltage
- Swell A momentary increase of the voltage relative to nominal
- Transient A very brief ( <0.5 cycle) fluctuation in the voltage
