Measurement method |
| ||||
Vrms, Arms |
|
| 10/122 cycle contiguous non overlapping intervals using 500/4162 samples per cycle in | ||
|
|
|
|
| accordance with IEC |
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 | ||
Vrms1⁄2 , Arms1⁄2 |
|
| Value is measured over 1 cycle, commencing at a fundamental zero crossing, and refreshed each | ||
|
|
|
|
| |
Harmonics |
|
| Calculated from | ||
|
|
|
|
| according to IEC |
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 |
Flicker |
|
| According to IEC | ||
|
|
|
|
| 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 |
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 |
|
|
|
|
| hysteresis value. The measurement is the square root of the mean of the squared Arms half |
|
|
|
|
| cycle values measured during the inrush duration. Each |
|
|
|
|
| |
|
|
|
|
| Cursors allow measurement of peak Arms half cycle. |
