9410 series Meter overview
Instantaneous
Your meter provides one second and half-cycle measurements, per phase and totals
for many values.
• Voltage and current
• Apparent power (kVA), active power (kW) and reactive power (kVAR)
• Power factor and frequency
• Voltage and current unbalance
Harmonics
Your meter provides harmonic distortion metering, recording and real-time values for
all voltage and current inputs.
• Individual harmonics (including magnitude and phase angle) up to the 63
rd
harmonic
• Total even harmonic distortion (TEHD) and total odd harmonic distortion (TOHD)
• Total harmonic distortion (THD) or total demand distortion (TDD)
• K-factor, Crest factor
Min/max recording
Your meter records new minimum and maximum data every recording interval for a
variety of values.
• Voltage and current
• kW, kVAR and kVA
• Power factor
• Frequency
• Voltage unbalance
• Plus any measured value
Power quality
Your meter measures and records voltage and current sags and swells.
Your meter also has many power quality related features.
• Disturbance direction detection: this allows the meter to analyze disturbance (sag/
swell) information to help determine the direction of the disturbance relative to the
meter.
• Setpoint learning: this allows the meter to learn the power quality characteristics of
your system, to help identify what constitutes a sag or a swell.
• COMTRADE: this allows the meter to save waveform data in COMmon format for
TRAnsient Data Exchange (COMTRADE) on its internal FTP server.
Your meter includes the following power quality compliance:
• EN50160: Your meter measures and presents statistics for determining EN50160
compliance.
• IEC 61000-4-30: Your meter complies with the IEC 61000-4-30 power quality
standard.
• IEC 62586: Your meter complies with the IEC 62586 power quality standard.
