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.

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).

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.

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.

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

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.
