LTTpro is the associated software for display, analysis and storage of the data, so that the measurement chain from sensors to data acquisition to software can be offered from a single source.
Thanks to a patented solution, no driver installation is required to get the devices up and running. As a result, the software is easy to configure. Simply connect the LTT device to the PC and plug in all sensors: the sampled analog and digital signals are immediately available in LTTpro for real time visualization, analysis and direct storage into many different file formats.
The software option “LTTproPowerAnalyzer”, specially developed for the LTTsmart, delivers high-performance electrical power analysis that is perfectly designed for modern electric motors at varying speeds. LTTsmart devices rely on highly optimized algorithms to precisely determine and display the rotation cycles, even at highly distorted phase current waveforms with heavy noise.
Apart from all typical power characteristics (RMS values, active/reactive/apparent power, power factors, speed, efficiency,…), the distortion (THD = Total Harmonic Distortion) of all phase currents and phase voltages is continually calculated and displayed.
Calculations based on half cycles and averaging across multiple cycles are also possible.
The parallel view of raw data and calculated PowerAnalyzer data immediately reveals the causes behind any anomalies in the key performance indicators.
At the press of a button or by setting an appropriate trigger event, entire time windows of raw data can be stored along with the corresponding calculated data from the PowerAnalyzer, down to the precise rotation, while the continuous power calculation keeps running.
The compact LTTsmart systems allow for both: operation at a test stand facility and mobile operation in a vehicle itself. In addition, the software LTTpro can also display, analyze and share previously recorded or emulated data, covering all requirements around driving cycles, vehicle testing and production monitoring,
This LTT-hardware/software package thus offers an efficient solution for measuring the power of an electric motor in testing environments as well as in real operation.
