SICAM Q200 – Multifunctional Power Meter and Recorder Specification for an IEC 62586-1 and IEC 61000-4-30 Ed. 3 Class A compliant Power 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.
