Siemos MR multifunction power quality analyser

Siemos MR multifunction power quality analyser

The new MR-Siemos multifunction power quality analyser is suitable for the analysis of three-phase LV networks for voltages to 690 volt (L-L) and currents to 5300 amps. The instrument is designed for cyclic data measurements (network frequency, voltages, currents, apparent, real and reactive power). Features include manually and automatically triggered oscilloscope recordings as well as manually and automatically triggered recordings of 10-msec RMS values and power quality events.

Up to 1,900 system parameters can be recorded over a long period of time with the internal, 1-Gbyte system memory. The WinPQ mobile software is especially adapted to the MR-Siemos power quality analyzer and allows both online evaluation of the measured parameters and a detailed evaluation after conclusion of a measurement interval. This is performed via offline transmission and evaluation of the data from the device to a PC. During on-line analysis mode, the voltage and current signal shapes can be presented in real time including harmonics spectra ranging to 5,000 Hz as well as intermediate harmonics. The DC portion of signals can also be evaluated which is an invaluable feature when transients are involved. The MR-Siemos power quality analyzer measures the direction of power flow of the harmonics at the measuring point in addition to active power, reactive power, harmonic reactive power, displacement factor (cos ?) and lambda power factor. In offline mode, detailed individual evaluations can be made as well as an automatically generated report based on previously defined limit values. Individual phase measurements for all cyclic parameters in measurement intervals between 1 second to 30 minutes include frequency, voltages, currents and powers. In addition, recordings of transient events can be evaluated as oscilloscope recordings or as recordings of 10-ms RMS values. The ability to record frequencies in the range from 0 Hz to 5 kHz allows evaluation of remote control signals. The WinPQ mobile software has an integrated report generator for high-speed statistical evaluation of measured values.
