Between 16 to 18% of the total charge of an electric car is consumed as electric drive system losses. Electric and hybrid car manufacturers therefore need to accurately evaluate motor and inverter control in order to achieve higher precision and greater efficiency. Additionally, the accurate analysis of inverter waveforms without interference from switching noise is a key part of evaluating the motor drive circuit.

Automotive Manufacturing – Measuring for efficiency

Two key criteria for successful development and mainstream adoption of (hybrid) electric vehicles are - reliability and driving range. The lower the loss in electric systems, the longer their lifetime and the more efficient the drivetrain, the longer the driving range. But as powertrains, charging systems, infotainment and safety systems grow more sophisticated in the ear of the connected car, hybrid and electric vehicle development requires mechatronic analyses of unprecedented certainty and flexibility.

More than a test tool 

Typically, a portable scope or test tool is used by an engineer to diagnose faults on a production line in real-time, or to carry out tests in a workshop. But how can faults be detected and diagnosed when they are intermittent and the engineer needs to be somewhere else? On the other hand, a portable data logger can capture lots of data, including the faults over a period of time, but requires the data to be searched and analysed later to make sense of it.

The WTViewerE is a powerful software that supports remote analysis and control of multichannel measurements from the WT series of Yokogawa power analyzers. In addition to real-time control of remote measurements in multiple formats and customizable layouts, the latest version of the software allows any 4 Yokogawa power analyzers regardless of configuration to be synchronized for multi-unit measurements.  This allows for sophisticated computations for larger applications that may need more than one power analyzer.

    Overview:

    This video demonstrates how to test to an IEC standard (IEC 61000) using a Yokogawa Test&Measurement WT5000 Precision Power Analyzer and the harmonic flicker testing software. The software automates the process of judging if the device under test is compliant with the chosen standard and allows you to output the necessary test reports for your records.

    Overview:

    Having multiple memory options allows engineering groups to optimize how data is stored, no matter if you need to record for a long time at slower sampling rates, do a fast capture at high sampling rates, or anything in between.

    The Yokogawa Test&Measurement DL950 ScopeCorder operates as an oscilloscope and incorporates the ability to record data for long periods of time like a data acquisition recorder. There are four memory types on the DL950 ScopeCorder: internal memory, solid state drive, flash memory, and PC storage through the IS8000 Integrated Test and Measurement Software Platform. This videos talks about the advantages of each of these and how to pick the best data recording method for you.

    Overview:

    This video demonstrates how to measure transient phenomena on power signals using the Yokogawa Test&Measurement PX8000 Precision Power Scope.

    In several applications, especially those testing AC power to a standard such as IEC61000-3-11, the voltage and current signals must be monitored to confirm there are no major dips and/or swells in the signal. This can be done with instruments capable of reporting rms values, including power analyzers, traditional oscilloscopes, and some data acquisition systems.

    To test to a standard, however, the instrument must have an accuracy spec that is traceable back to a national standard of calibration such as ISO17025 or NIST.

    Overview:

    In this video we demonstrate the GPS data logging capability of the DL350 Portable ScopeCorder. Recording Position, Velocity, and Altitude simultaneously with accelerometers or other analog inputs is simple with the DL350's built-in features.
