Energy Measurement

The power consumption of everyday home and office electrical appliances is of importance to consumers and generators of electricity alike.

When the power consumption varies over time, then integration of the power (W-hr integration) is required.

IEC 61000-3 Harmonics & Flicker Testing

Until today, the accurate measurement of harmonics and flicker for ‘CE’ marking of products has been the domain of expensively equipped EMC labs. The Harmonics and Flicker measuring option for the Voltech PM1000+ power analyzer is a revolution in the way these measurements will be made. For the first-time engineers designing and testing electrical products will have a compact, benchtop solution that will enable them to test their product at every stage of development. This will give engineers a high degree of confidence before they ultimately submit their product for full compliance testing. Testing with the PM1000+ will help highlight potential problems, significantly reducing time-to-market and minimizing expensive EMC lab re-test.

  • Harmonics to EN61000-3-2 (pre-compliance)
  • Flicker to EN61000-3-3 (pre-compliance)
  • Harmonics including inter-harmonic groups to EN61000-4-7
  • AC source and impedance network not required (pre-compliance)
  • Check compliance at every design stage
  • Avoid expensive EMC lab re-test
  • PASS / FAIL result and comprehensive diagnostic reports
  • PC software operates over USB (all models) or GPIB (communications model)

Using algorithms from the certified PM6000 power analyzer (as used by leading EMC labs) the PM1000+ analyzer provides many of the key measurements in one cost effective benchtop instrument. The results are obtained using proprietary software in the analyzer and processed and presented by PC software. The PC software configures the instrument automatically and provides detailed diagnostic results similar to those from an EMC lab, showing results against the limits of IEC61000-3-2 and IEC61000-3-3. The measurements are right up-to-date with the standards, including the measurement of inter-harmonic groups and licker.

Such measurements will help identify problems during the early stages of a development, instead of at the final EMC certification.
