LTTpro for LTTsmart Power Analysis

Thanks to a patented solution, no driver is required for our LTTpro software. This means that the software can be set up quickly and easily. Simply plug in the device, connect the sensors and your measurement data is immediately visible, which can be recorded in analog and digital form in real time and saved directly in a variety of common formats.

The “LTTpro Power Analyzer” software option specially developed for the LTTsmart offers high-performance electrical power measurement that is perfectly designed for modern electric drives at varying speeds. Our LTTsmart uses highly optimized algorithms to determine and display the exact rotation cycles even from very noisy phase current sine curves. In addition to all the usual power characteristics (RMS values, reactive/apparent/active power, power factors, speed, efficiency, etc.), the distortions (THD = total harmonic distortion) of all phase currents and voltages are also continuously determined and displayed.

Calculations on a half-cycle basis and averaging over several cycles are also possible.

The parallel view of raw data and calculated Power Analyzer data immediately reveals the causes behind any anomalies in the key performance indicators.

At the push of a button or via configurable trigger events, entire raw data time windows can be saved together with the associated calculated Power Analyzer key figures with turnaround accuracy, while the power calculation simply continues.

The compact LTTsmart systems can not only be operated on the test bench, but also conveniently on the move directly in the vehicle. In addition, the software can also display, analyze and transfer previously recorded or emulated data, so that all requirements relating to driving cycles, vehicle testing, production monitoring, development and optimization are covered.

The LTT hardware and software package therefore offers an efficient solution for measuring the performance of an electric motor in the test field and in real use!
