A PQ expert can link an abnormal current or voltage waveform to an abnormal condition on a power system just as a handwriting expert matches a signature to a person. Many facilities now have online ...

The first major performance item to review is large-signal load-transient response performance. Here, a large-signal phrase is used in contrast to a small-signal. A small-signal transient literally ...

Traditional methods of measuring low-current AC waveforms using an oscilloscope have many limitations, including limited dynamic range, insufficient bandwidth and poor signal resolution. Keysight’s ...

Power architects engaged in designing systems requiring low output noise and fast transient response — such as RF transmitters, power amplifiers, test systems, displays, designs supporting low-voltage ...

Editor's note: This article was first featured in the February 2003 issue of EC&M. It has been updated to reflect newer power quality instruments and updated standards. Today, many facilities have ...
