Quality Instrument and Recorder
The device shall be a Class A multifunctional measurement device with the main purpose of
measure and monitor the power quality according to IEC 62586-1 product standard. The device
shall encompass all important quantities for the assessment of electrical supply networks. The
recorder shall acquire, display, analyze and communicate measured electrical quantities of the
electrical network. The following electrical quantities have to be acquired at a minimum: AC
voltage, AC current, frequency, harmonics, interharmonics, flicker, power, energy, power factor,
THD.
The acquisition and calculation has to be according to the standard IEC 61000-4-30 Ed. 3 Class
A power quality measurement standard. The device has to provide the possibility of long term
data evaluation directly in the device with the possibility of displaying a report in accordance
with power quality standard such as EN 50160.
The device shall come with an integrated display providing easy display of measured real time
quantities of the electrical network.
For configuration and evaluation the power quality recorder has to feature an integrated webserver providing easy to use parameterization and evaluation functionality. No additional
software for device settings shall be used.
The device must incorporate at least 2GB internal memory for historical data.
The device must allow connection over MODBUS RTU Master of up to 8 slave MODBUS RTU
RTU devices.
Measurement inputs, binary inputs and outputs
 4 inputs for AC voltage measurements up to 400V (L-N/PE), 690V (L-L) rated input
voltage
 4 inputs for AC current measurements, rated input current AC 1A or 5A
 Sampling rate per channel: 40,96 kHz
 Up to 6 binary inputs and 6 binary outputs
Continuous measured of the following quantities:
 Magnitude of voltage U
 Magnitude of current I
 Power frequency f
 Active power P
 Reactive power Q and Q1 (fundamental component)
 Apparent power S
 Active power factor cos phi
 Measurements up to the 63rd harmonics order of voltage and current
 Interharmonics of voltage and current


supraharmonics of voltage in the range of 2 kHz to 9 kHz
Mains signalling voltage detection
Event-specific measured value acquisition:
 Min./max./mean values with configurable intervals - (1, 10m or 2 h)
 Recording of events: voltage dips, swells, interruptions: with 1/2 cycle continuous
monitoring and recording with magnitude and time stamp (duration)
 Rapid voltage changes (RVC)
 Limit value violations
 Waveform capture of triggered events of voltage and current. Up to 10 seconds records
must be possible.
Harmonic Directions
Harmonics of voltages, currents, and powers up to the 63rd order according to the
IEC 61000-4-7 standard.
The following values are given for each harmonic:
• RMS value (for power: RMS value and sign)
• Phase angle
The sign of the active power of the single harmonic can indicate the direction of the power flow
of this harmonic in a system from the device installation point of view. Thus, it is possible to
indicate loads that generate the harmonics and that are probably the cause of the harmonics.
For voltage and current, the given phase angle of the harmonic refers to the voltage of the
fundamental component in the respective phase. The phase angle between the current
harmonic and the corresponding voltage harmonic is used to calculate the sign of the active
harmonic power.
