Power Systems Analysis

SDC Industries can provide Power System Analysis on any electrical distribution system, using a portable handheld power monitor. The power monitor has simultaneous eight channel capture to measure, record and analyse power quality, harmonics and energy for any single or three-phase circuits.

The above parameters can be viewed using the following methods:

• Scope mode showing real time viewing of voltage/current waveforms and phasor diagrams
• Metering mode showing the selected parameters updated every second
• View data mode in which the recorded data can be viewed easily to show where problems exist
• Time plot mode which displays a graph of the selected parameter since recording began up to a maximum of 10 days.

The power monitor measures the following parameters:

• true volts RMS and amps RMS
• watts, volts amps and volt amps reactive
• power factor
• frequency (30-450Hz fundamental)
• voltage unbalance
• voltage total harmonic distortion
• current total harmonic distortion
• current crest factor
• nth harmonic, voltage/current
• K factor
• demand, energy, sags and swells
• individual harmonics to the 50Hz fundamental frequency
• voltage/current transients.
