Klaus LangKlaus Lang studied telecommunications at the University of the German Telekom in Dieburg. He joined GOULD as Product Specialist for paper recorders and digital data recorders. After the acquisition of GOULD by NICOLET he took over Product Management responsibilities for the NICOLET transient recorders and for digital storage oscilloscopes. After NICOLET became part of LDS, he was responsible for Product Marketing of NICOLET DAQ Systems, DACTRON Dynamic Signal Analyzers and LDS shakers. Since HBM (now HBK) acquired LDS in 2009, he is now Global Business Development Manager for Electric Power Testing.
Using advanced power analysis methods to shorten test time
In this presentation two advanced methods of power analysis will be explained, both significantly shortening the test time for electric drives. The first one is a dynamic power measurement method (based on switching frequency, patent pending). This allows machine mapping and WLTP testing in parallel, rather than in series. The second one is cycle recording based power analysis using advanced cycle detection and this method allows dynamically reduced setpoint test time with increasing rpm and thus shortens the total test time of an electric motor.
