Method and Apparatus for a Cloud-Based Power Quality Monitor
First Claim
1. A system comprising:
- a plurality of power quality devices for continuously measuring and buffering data including at least one of RMS voltage, RMS current, real, reactive and apparent power, power factor, displacement power factor, phase angle, harmonic magnitudes and phases, interharmonics, IFL, Pst, and Plt flicker, symmetrical components, phasors, aggregating triggered waveforms, and transients, and periodically transmitting the buffered data; and
one or more cloud-based servers communicatively coupled to the plurality power quality devices, the one or more cloud-based servers operable to;
receive the buffered data transmitted by the plurality of power quality devices;
decompress and store the buffered data in a database or a file system;
display on a web page one or more of a stripchart, daily profile, histogram, waveform, vector diagram, harmonic bar chart, and 3D harmonic graph generated using the stored data; and
correlate an event alert received from a first of the plurality of power quality devices with data received from a second of the plurality of power quality devices.

Abstract
A system includes a plurality of power quality devices for continuously measuring and buffering power quality data and transmitting the buffered power quality data on a periodic basis and one or more cloud-based servers communicatively coupled to the plurality of power quality devices. The one or more cloud-based servers are operable to: receive the buffered data transmitted by the power quality devices; decompress and store the buffered data in a database; and display on a web page one or more of a stripchart, daily profile, histogram, waveform, vector diagram, harmonic bar chart, and 3D harmonic graph generated using the stored data. The system also includes one or more computing devices communicatively coupled to the plurality of power quality devices and the one or more cloud-based servers.

11. A computer-implemented method, the method comprising:
-
receiving, from a first power quality device, at least one of an RMS voltage, an RMS current, a power factor, a displacement power factor, a phase angle, harmonic magnitudes and phases, interharmonics, IFL, Pst, and Plt flicker, symmetrical components, phasors, aggregated triggered waveforms, and transients approximately every five minutes; displaying a map on a web page, wherein the map comprises a marker indicating a location of the first power quality device and a second power quality device; displaying on the web page at least one chart or graph showing one or more of the RMS voltage, the RMS current, the power factor, the displacement power factor, the phase angle, the harmonic magnitudes and phases, the interharmonics, the IFL, the Pst, and Plt flicker, the symmetrical components, the phasors, the aggregated triggered waveforms, and the transients; receiving, from the first power quality device, a triggered condition alert; and identifying at least one related event based on data received from the second power quality device. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
