The Power Analyser CASSY is a combination of an isolated and differential oscilloscope, multimeter, wattmeter, energy analyser and recorder. It is designed for demonstration and laboratory experiments.

The Power Analyser CASSY is suited to the following areas of application:

Energy networks

  • Voltage and frequency stability
  • Load behaviour of networks
  • Effect of harmonics

Electrical machines

  • Inrush current from transformers and machines
  • Transformation ratio of transformers
  • Efficiency of machines

Power electronics

  • Rectifier
  • DC/DC converter
  • DC/AC converter
  • Frequency converter
  • Filter


  • simultaneous measurement of U, I, φU, φI, f and P
    • instantaneous values U, I and P
    • averaged values U, I and P
    • RMS values (AC+DC) U and I
    • fundamental wave filters
    • Delta connection adjustment
  • universal connection options
    • via USB connection with PC or laptop
    • via WiFi with the school network or setting up an access point
  • automatic or manual range selection
  • supports the prize-winning measurement software CASSY Lab 2 for computer-aided measurements and simple to highly complex evaluations:
    • Electrical power calculation S, P, QC and QL
    • Electrical work WS, W and WQ
    • Resistance calculation R, Z, XC, XL, G, Y BC and BL
    • Positive sequence component, negative sequence component and zero sequence component in 3-phase systems
    • Time derivative, integral over time, FFT analysis, mean value, histogram, and modelling
    • Drivers for LabVIEW and MATLAB available
  • Possibility of direct manual operation of the device by means of a rotary selector with cursor keys direct value readings on 9 cm backlit display
    • Display of up to 24 measured values on one display
    • Display of all values for each channel
    • Display of all values in tabular form
    • Display of measured values in a diagram
    • Display of a vector diagram
  • wireless connection to the CASSY app via WiFi for experimentation with tablets and smartphones (iOS, Android and Windows)
  • Measuring instrument category CATIII 300: allows the use of the measuring instrument for
    tests with safety extra-low voltage (SELV) via 3-phase systems with or without neutral conductor, up to testing in power electronics, e.g. DC link voltage of 700 V DC
  • Real-time processing in the device enables comprehensive network analysis in the three-phase networks, which are displayed directly on the device in the vector diagram
