Power Quality Survey

In certain cases, a power quality survey will highlight issues that can be addressed by a simple fix, while in others a complex design solution may be required to solve the problem. Modern power electronics are susceptible even to minor power supply variations. At Premium Power, we strive to project manage the customer’s power quality issues all the way from identification to the solution. Our three main areas of expertise in relation to power quality are power quality surveys, power quality monitoring and power quality solutions.

Power Quality Survey

This solution is for customers who know that they have a specific power quality issue, usually the presence of harmonics in the electrical system. A power Quality survey involves:

  • Temporarily installing intelligent power meters in the electrical network
  • Collecting power data over a period of 2-3 weeks
  • Analysing collected data and issuing detailed reports

This study is particularly suited to detection of harmonics in the system, for other power quality issues like sags and swells and voltage unbalance.

The report focuses primarily on

  • Harmonic injection levels in the electrical network
  • Remedial measures to remove the harmonics from the system

Long-Term Power Quality System

The long term solution is for

  • Sites that have ongoing power quality issues
  • Issues that centre around voltage levels rather than harmonics

Premium Power specialise in the installation and integration of advanced permanent metering and software solutions. We offer support in detailed analysis of collected power quality data and reporting and issuing of corrective action directives.

We can also help train engineers so they can collect and analyse the power quality data themselves on an ongoing basis.

If you think that you would like to have your whole site inspected and power quality managed contact us today.

 Power Quality Problems

1. Power Quality Surveys

A solution is for customers who know that they have a specific power quality issue, usually the presence of harmonics in the electrical system. A power quality survey involves:

  • Temporarily installing intelligent power meters in an electrical network
  • Collecting power data over a period of 1-6 weeks
  • Analysing collected data and issuing detailed reports

These studies are particularly suited to detection of harmonics in the system. Other power quality issues will be identified, like sags, swells and voltage unbalance . We recommend the long term solution as a large amount of power quality data is required to make a decision about the presence of other power quality defects.

2. Permanent Power Quality Monitoring

Premium Power specialise in

  • Permanent installation and integration of advanced metering and software solutions
  • Detailed analysis of collected power quality data
  • Reporting and issuing corrective action directives

Alternatively, we can help train engineers so they can collect and analyse the power quality data themselves on an ongoing basis.

Power Quality Management

You should talk to us about power quality management if:

  • You have critical loads
  • You wish to maintain reliability of sensitive loads.
  • You wish to avoid damage to  sensitive equipment and you are experiencing high harmonic  distortion levels.
  • Maintain optimum reliability and design
