Summary
Data
(THVD) Displays the Total Harmonic Distortion of the utility Line/Load voltage as a
percentage
(THID) Displays the Total Harmonic Distortion of the utility Line/Load current as a
percentage
Displays three-phase real power (P) of the filter input/output in kW
Displays three-phase reactive power (Q) of the filter input/output in kVAR
Displays three-phase apparent power (S) of the filter input/output in kVA
Displays filters output power factor. 1.00 indicates unity power factor. A negative power
factor indicates lagging power factor
Displays the current utility line frequency in Hz
Displays the supply voltage into the HarmonicGuard
®
Low Capacitance filter
Displays the filters input/output phase current in Amps RMS
Displays board temperature
Waveforms
The PQconnect PC application supports capture and display of real time system voltage
and current data. Three phase waveform data can be viewed for Filter Line/Load Voltage,
and Filter Line/Load Current.
Phase A – Black
Phase B – Red
Phase C – Blue
Harmonic Spectrum (Left toggle to zoom in on the spectrum and right to increase the
spectrum to the 50
th
harmonic) the value of the fundamental is 100.
Status
Detections
Status alerts for the input, output and of the filter will display according to severity of the
alerts.
Hovering over status alert will give a brief description of what the problem may be.
