Early detection of shortages is therefore necessary and trend analyzes of various parameters can be helpful. Additionally, the obligation to prove the quality of the power supply system has changed and commercial aspects are also getting more and more important. Disturbance Analysis Simple recordings of voltage are source for the interpretation of power supply. In order to be able to be more precise and find solutions, it is not sufficient to calculate the voltage by means of average values of 10 minutes. Transient recorders with acquisi- tion rates of Mega Hz even detect fastest disturbance peaks and are essential for the exact analysis. Harmonics Analysis The topic harmonics also becomes a new important aspect. If you have done the analysis of up to the 25th or even 50th harmonics, you can now go far beyond that. The frequency spectrum of 2-9 Hz has been redefined and in the future it will be analyzed in 200 Hz bands. The combination of this new standard and the formerly used harmon- ics standards is the main task of up-to-date power quality analyzers. DEwETron has acted on this subject by creating the very latest generation of software and covering the whole spectrum of harmonics, interharmonics, frequency bands and grouping methods. Standard measurements with pre-defined and standardised setups are included or individual settings can be done by the users themselves. Flicker and More The standard software package includes flicker, unbalance, calculation of power and frequency etc. as well as a report generator with which one can print pre-defined reports (e.g. En50160) on the one side and create individual reports on the other side. Energy Analysis The consumption of energy as well as the energy costs are rising. The reduction of energy costs is hence one major topic of interest. Treaties and prices are relevant – the effective consumption as well. In order to be able to reduce the consumption, one has to know the exact energy consumption and the internal power flow. In order to be able to measure this, multi-channel measurement instruments are nec- essary. Using these instruments one can measure the consumption on several lines at the same time. This can also be done in parallel ways in different distribution boxes or even buildings. with the help of the report generator one can create simple reports on power flow and distribution of energy consumption. The export interfaces support a quick exchange of data with other analysis software packages.

This toolbox is an excellent combination of many features and nearly all applications can be realised by using DEwETron equipment. Beside the exact calibration the frequency calculation is a central feature of this software. 50 Hz and 60 Hz are a must – for us also 16 2/3, 400 and 800 Hz as well as DC software and variable frequencies (driver) are a necessity. Due to the high acquisition rate (mainly dependent on the AD card in use, up to 1 MS/s) and the DAQP-HV module there is no limitation of the acquisition of PwM drivers (300 kHz electrical band width) and the calculation of active and reactive power, power factor etc … The toolbox with the power quality parameters such as harmonics, interhar- monics, THD, symmetric components, flicker and its combination with the numerous trigger possibilities make the equipment a power analyzer with nearly no limitations. Several screen elements such as vector scopes, harmonics monitor, oscilloscope and diagrams allow a perfect online visualisation of the data. The integration of counter inputs, video and CAn-Bus offers additional data sources. The mathematical library additionally offers the possibility to calculate parameters such as torque and angular velocity or even determine the efficiencies online. wiring schematics Various wiring schematics allow the following connections of instruments: single-phase connection, star-connection, delta-connection, V-connection, Aron-connection, two-phase-connection and a combined star-/delta-connection – of course all with or without electric current.

Calibration/Accuracy The high accuracy of the calculation can be reached because of the calibration function in the frequency domain. with this unique technology amplitude and phase can be corrected for the full frequency range from DC up to whatever the hardware can sample (kilosamples up to megasamples per second). All internal curves like filter response or multiplexer shift are corrected inside the software and the sensor database includes correction curves for each clamp, rogowski coil, transformer or which sensor ever is used. 10 www.dewetron.com EnErgy & PowEr FUrTHEr AnAlySIS EnErgy & PowEr oTHEr FUnCTIonS other Functions Video The parallel usage of the synchronous DEwESoft VIDEo function allows the user to store videos in parallel with the data recording and opens a wide range of applications – whenever optical information is needed! remote Control with the remote control ability the instrument can be configured and the data can be evaluated from your office or wherever you are.
