IntroductionWhile we've enjoyed enormous benefits from the evolution of solid state technology, the fact is that the microelectronics at the heart of that technology requires clean power. Faster speeds and lower voltages mean that there is less and less tolerance for anything less than quality power.
Power Quality (PQ) covers a wide range of issues, from voltage disturbances like sags, swells, outages and transients, to current harmonics, to performance wiring and grounding. The symptoms of poor PQ include intermittent lock-ups and resets, corrupted data, premature equipment failure, overheating of components for no apparent cause, etc. The ultimate cost is in downtime, decreased productivity and frustrated personnel.
This application note gives you information on how to troubleshoot PQ problems. It also gives you information on how to start fixing those problems. But before grabbing that meter, please read the following cautionary notes:
- Suggested measurements should only be made by qualified personnel who have been trained to make these measurements in a safe manner, using proper procedures and test tools rated for work on electrical power circuits.
- To the best of our knowledge, recommended solutions are consistent with the National Electric Code (NEC), but in any case, NEC requirements must not be violated.
- We have tried to make the information accurate and current, but it is not intended to be a substitute for the specialized knowledge and experience of professional power quality practitioners.
What this application note offers is a "starter kit", not the final word on PQ troubleshooting.
