THE NEW GENERATION OF INNOVATIVE MEASUREMENT TECHNOLOGY

../../fileadmin/user upload/LD Didactic/Bilder/Neuheiten/Neuheiten 2018/PAC 500x550 PX

With the Power Analyser CASSY, LD DIDACTIC presents, for the first time, an innovative measurement system for electrical engineering designed in-house. The new measuring instruments meet all the requirements of the most modern measurement technology in the areas of drive technology, power electronics, electrical machines and power engineering. Can be used as a table-top device or as part of the TPS - Training Panel System framework system.

  • automatic or manual range selection
  • supports the price-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 three-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 three-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 three-phase
    systems, which are displayed directly on the device in the vector diagram
  • The Power Analyser CASSY Plus provides measurements for the instantaneous values of U, I and P in measurement channels A-D from the ±10 V outputs U-X. The amplification depends on the measuring ranges.
