Overview

Overview
Trend categories HDPQ Xplorer is able to display statistical trends or plots for the following parameter
categories:
Standard: Parameters include the Basic (basic volts and amps), Computed Basic
(displacement power factor, residual and net current), Power, Standard Demand,
Standard Energy, Harmonics and Standard Flicker. These power parameters are
measured more accurately using a one (1) second interval, summarized by min, max
and avg values at the end of the interval.
Distortion TIF RMS, THD, Frequency: Parameters include voltage and current THD,
voltage and current TID, voltage and current TIF rms, crest factor, signed and unsigned
harmonic, and transformer factor.
Unbalance: Parameters include positive, negative and zero sequence components for
voltage and current, as well as NEMA max-deviation from average method.
Advanced Power: Parameters include power factor calculated using arithmetic and
vector sums of the individual phases.
Advanced Demand: Parameters include peak power, predicted demand, coincident
power, and coincident power factor parameters. These parameters measure the ratio of
maximum demand of the power distribution system to the total connected load of the
system.
Advanced Energy: Parameters include energy on per phase and total basis as well as in
forward and reverse mode.
Advanced Flicker: Parameters used primarily for specialized testing. Advanced Flicker
parameters are calculated as per IEC 61000-4-15.
NOTE: See Chapter 4 Setup Monitoring for the detailed list of parameters available for
trending.
