World's Smallest High-Precision Power Analyzer

Dewesoft Power Analyzer is not only the smallest power analyzer in the world, but it's also the most powerful one. The flexible hardware platform combined with powerful software features gives unique testing possibilities for any kind of electrical measurement.
Picture
More Than Just a Power Analyzer

Dewesoft power meters have many advantages compared to conventional power analyzers and provide the most flexible solution for all power analysis calculations as well as electrical power and mechanical power measurements. Combined with the power quality analyzer capabilities it is a perfect solution. Major advantages of Dewesoft power analyzer are:

​Combination of multiple products in a single device - Power Analyzer, Combustion Analyzer, Oscilloscope, RAW Data Logger, Spectrum Analyzer, CAN logger, etc.
Synchronous acquisition of all data - electrical data mechanical data vehicle bus data, positioning data, video, etc.
Data storage in one system and one data file format.
Combined power analysis and raw data storing.
Live, on-line and real-time power calculation (1 ms values).
Enhanced power quality analysis.
Any number and type of input channels - Voltage, Current, IEPE/ICP strain, thermocouple, RTD, CAN, etc.
​Modular and mobile measurement system with SSD storage, fast CPU processor, integrated display and batteries for stand-alone use. 
Additional sensor software calibration.

All these features provide a comprehensive power analysis system within one measurement device. No more complications with data synchronization, visualization, storage or data comparison. Dewesoft power analyzer solves all these problems.
Picture
High Precision Power Analysis

Dewesoft DAQ Systems are unique due to the powerful software which combines the functionality of multiple devices packed into a compact, flexible and rugged hardware.

For power analysis, highly accurate amplifiers are unquestionably necessary. The SIRIUS system offers high-speed amplifiers integrated into the high and low voltage inputs reach new dimensions in measurement accuracy. These amplifiers possess a basic accuracy from DC to 1 kHz of 0.03% of reading. This is unique on the power analyzer market, especially for variable frequency drives where it is absolutely necessary to reach the highest possible accuracy for all measurements.

Other manufacturers often have high accuracies at 50/60 Hz but the accuracies above and below these frequency spectrums leave a lot to be desired. Please refer to the grey line in the chart.
Picture
Sensor Correction Software

Voltage and current transducers always have a frequency dependent amplitude error and phase shift.

Dewesoft unique software calibration technology amplitude and phase can be corrected for the full frequency range from DC up to 1 MHz (e.g. iron-core clamp, AC/DC clamp, Rogowsky coils, grid current and voltage transducer).
Picture
Different Power Analysis Wiring Schematics

Dewesoft data acquisition software provides a visual selection of the different wiring schematics and provides power calculations for all possible connections.

The following predefined power schematics are available:
Direct current
Single-phase
Two-phase
Star connection
Delta connection
V connection
Aron connection and a combined star / delta connection

All of these connections can be measured with or without currents. Dewesoft has the ability to analyze 6, 7, 9 or 12-phase motors due to the modular construction of our measurement devices and multiple synchronized power modules in our powerful software.
Power Calculations

Dewesoft X data acquisition software will automatically calculate and store not only raw data from the voltage and current channels but also all the power values such as:

P, Q, S, D
Cos ϕ, power factor
​P, Q, cos ​ϕ  for each harmonic

Each parameter can be displayed visually in a time recorder, graph or in digital and analog displays. Perfect for harmonic analysis as well as phase power, voltage, current and many other power visualizations.
Picture
Frequency Source Selection

Dewesoft power analyzer and power meters allow the user to choose the frequency source for the measurement. The measurement frequency source can be either:

Voltage, current or an external frequency source

This is very helpful feature, especially when performing measurements on an inverter. Due to the PWM modulated voltage signal, the correct period of time can often not be determined correctly. The current signal is much less distorted because of the high inductance in the motor coil. Therefore, more often than not it's better to use the current signal as a frequency source with inverter measurements. This feature ensures correct frequency determination for every application.
Picture
Oscilloscope & Vectorscope

Oscilloscope
Selectable graphs
U1, U2, U3, U12, U23, U31: Line to line and line to earth voltages are supported
Up to 8 graphs in one diagram
Zoom in and out are supported online
Waveforms can be stored

Vectorscope
​Vectorscope for 3 phase systems
Each individual harmonic can be displayed
Multiple vectorscopes can be displayed at once
Different power systems can be displayed
Direct comparisons of phasors are possible with the transparent function
Recorder & X/Y Recorder

Dewesoft power analyzer provides visual recorder displays for time-domain data.

Recorder

​Recording of all parameters in individual intervals
Individual screens can be defined
Zoom in and out, pinch to zoom on multi-touch displays
Storing fast (full sampling rate) or reduced (e.g. 600 sec)
Detailed zoom-in to the pulse width

X/Y Recorder
Orbitals can be generated online
P over Q as an example for this function
Picture
Fault & Transient Recorder

Dewesoft power analyzer can also be used as a fault and transient recorder. The software features advanced triggering capabilities:

It is possible to trigger all channels (analog, digital, power, math, etc)
Setting a trigger on all parameters of the power module
U, I, P, Q, S, D, cos ϕ, power factor, etc.
Every individual harmonic
​Positive, negative, zero-sequence systems
Very fast glitch detection (up to MS/s)
Mathematical channels like rpm, torque, efficiency, etc.
Math formulas can be used to create combined trigger conditions, fro any measurement parameters.

When the trigger event happens, data is stored with a fast sampling rate (with pre- and post-time). For the rest of the measurement only reduced datasets (min, max, average, RMS) are stored. This reduces the file size for long-term measurements.
Picture
Sensor Calibration & Sensor Accuracy

​Voltage and current transducers always have a frequency-dependent amplitude error and phase shift.
​Dewesoft unique software calibration technology amplitude and phase can be corrected for the full frequency range from DC up to 1 MHz.

All the internal curves like filter response are connected inside the software and the sensor database includes correction curves for each current clamp, Rogowski, coil, voltage transformer or whichever sensor is used.
Picture
Integrated Sensor Power Supply

Dewesoft SIRIUS MCTS is the power supply unit for our high-precision current sensors and transducers.

MCTS power supply slice can either come in rack slide-in slice to fit into Dewesoft data acquisition systems or is available as a stand-alone modular unit compatible with SIRIUS modular slices.
