See the LTTsmart power analyzer with the LTTpro measurement software live in action on an exemplary test bench, presented by Michael Tasler
We set up a test bench in Würzburg to present the LTTsmart Power Analyzer and the driver-free LTTpro measurement software.
The expert and CEO of Labortechnik Tasler GmbH, Michael Tasler, connected a 3-phase electric motor to the power analyzer and connected it to the computer via USB. As soon as Mr. Tasler activates the electric motor, LTTpro immediately displays the incoming measurement data in high synchronization with each revolution of the motor. Important measurement data in this case are reactive, active and apparent power. These are shown in the lower display. You can easily “zoom in” here to find out more details about the data.
This can be easily explained with the help of the display of the “Total Harmonic Distortion” (harmonic components from voltage and current) of the desired sinusoidal current of the integrated online math functions. When starting and stopping the electric motor, logical distortions are displayed within the measurement. However, as soon as the motor is running, certain standard levels can be seen. Due to the sampling rate of 4 MHz, the harmonic components of the current (approx. 32%) and the chopped voltage (approx. 135%) are displayed. These are very good values. At a lower sampling rate (e.g. 1 MHz), it can be observed that the measurement can no longer display a normal curve. The harmonic components are therefore no longer determined at a low sampling rate, which can be a decisive disadvantage in electronic power measurement. The optimum here is therefore between 2 and 4 MHz.
Labortechnik Tasler (LTT) has been offering measurement technology with such precision for over 25 years and can therefore draw on unparalleled expertise. In addition, our solution does not have to be operated stand-alone, but can also be used in conjunction with other metrological solutions.
