Transient Capture with the Vision and Revolution
Capture high-speed, high-voltage transients with the Revolution and Vision, using the optional transient capture system. Transient capture uses 1 MHz sampling for voltage, giving a 1 microsecond sample window, and…
Part 2 Computing Event Duration with Interval Data
Previously, a method was shown to compute cycle event durations with one minute interval data and one-second timestamps from Significant Change data. In this whitepaper, a method is given that…
Formulas for Power and Harmonic Measurements
PMI recorders use a variety of algorithms to compute RMS voltage and current, real, reactive, and apparent power, true and displacement power factor, and phase angle. The formulas for these…
Voltage Unbalance with Single Phase Boomerangs in Canvass
Canvass now includes the ability to perform voltage unbalance studies using single-phase Boomerangs. Logical groupings of three Boomerangs may be created, and treated as a single 3-phase device. This virtual…
Waveshape Triggering for Waveform Capture
A new method of triggering waveform capture in the Revolution and Vision is introduced, designed for capturing changes in power line waveform shape.
Histograms in Canvass
The Canvass Histogram is a graphical method for analysis of RMS voltage data over long time periods. Additional statistical measures are automatically derived from the histogram.
