Measurement method

 

Vrms, Arms

 

 

10/122 cycle contiguous non overlapping intervals using 500/4162 samples per cycle in

 

 

 

 

 

accordance with IEC 61000-4-30

Vpeak, Apeak

 

 

Absolute highest sample value within 10/122 cycle interval with 40 µs sample resolution

V Crest Factor

 

 

Measures ratio between the Vpeak and Vrms

A Crest Factor

 

 

Measures ratio between the Apeak and Arms

Hz

 

 

Measured every 10 sec in accordance with IEC61000-4-30

Vrms12 , Arms12

 

 

Value is measured over 1 cycle, commencing at a fundamental zero crossing, and refreshed each

 

 

 

 

 

half-cycle. This technique is independent for each channel in accordance with IEC 61000-4-30.

Harmonics

 

 

Calculated from 10/12-cycle gapless harmonic group measurements on Voltage and Amps

 

 

 

 

 

according to IEC 61000-4-7

Watt

 

 

Selectable Total or Fundamental real power display

 

 

 

 

 

Calculates average value of instantaneous power over 10/12 cycle period for each phase

 

 

 

 

 

Total Active Power PT =P1 + P2 + P3

VA

 

 

Selectable Total or Fundamental apparent power display

 

 

 

 

 

Calculates apparent power using Vrms x Arms value over 10/12 cycle period

 

 

 

 

 

Total Apparent Power is root mean square of real and apparent power

VAR

 

 

Selectable Total of Fundamental reactive power display

 

 

 

 

 

Calculates reactive power as root of VA squared minus Watt squared over 10/12 cycle period

 

 

 

 

 

Capacitive and inductive load is indicated with capacitor and inductor icons

Power Factor

 

 

Calculated Watt / VA

Cos ϕ / DPF

 

 

Cos of angle between fundamental voltage and current

 

 

 

 

Unbalance

 

 

The supply voltage unbalance is evaluated using the method of symmetrical components

 

 

 

 

 

according to IEC61000-4-30

Flicker

 

 

According to IEC 61000-4-15 Flickermeter - Functional and design specification

 

 

 

 

 

Includes 230 V 50 Hz lamp and 120 V 60 Hz lamp models

Transient capture

 

 

Captures waveform triggered on signal envelope

 

 

 

 

 

Additionally triggers on dips, swells, interruptions and Amps level as specified by IEC61000-4-30

Inrush current

 

 

The inrush current begins when the Arms half cycle rises above the inrush threshold, and ends

 

 

 

 

 

when the Arms half cycle rms is equal to or below the inrush threshold minus a user-selected

 

 

 

 

 

hysteresis value. The measurement is the square root of the mean of the squared Arms half

 

 

 

 

 

cycle values measured during the inrush duration. Each half-cycle interval is contiguous and

 

 

 

 

 

non-overlapping as recommended by IEC 61000-4-30. Markers indicate inrush duration.

 

 

 

 

 

Cursors allow measurement of peak Arms half cycle.
