Frequently asked questions
What's the difference between a voltage sag and a brownout? +
A sag is a brief dip (milliseconds to seconds) from high inrush loads starting nearby. A brownout is sustained low voltage (hours to days). VFDs and induction motors can cause sags; utility issues cause brownouts. We log both with a power-quality meter and recommend fixes.
Can harmonics damage motors or shorten equipment life? +
Yes. Harmonics increase motor heating, reduce efficiency, and shorten insulation life. VFDs and switching power supplies create harmonics. If your facility has many VFDs and equipment misbehaves (nuisance tripping, overheating), harmonic analysis is critical. We measure and design filters.
Should we install power-factor correction equipment? +
That decision depends on utility data, measured load conditions and existing equipment. The load profile must be reviewed before recommending correction equipment.
