Energy consumption in low-power and standby modes is an important issue due to increased awareness that energy resources are becoming limited and demand for energy-saving household electrical appliances continues to grow. IEC62301 Ed2.0 (2011) and EN 50564:2011 define standby mode as the lowest energy consumption of an appliance not performing its main function, when connected to the mains. IEC62301 Ed2.0 (2011) defines test methods and requirements for both the mains supply and the test equipment. It is crucial that design and test engineers choose highly accurate power measurement tools to confirm that their devices meet these requirements.

    The Power Consumption Measuring Software from Yokogawa Test&Measurement provides a comprehensive solution for standby power testing and meets the requirements of:

    • IEC 62301:2011 Ed2.0 – Household electrical appliances (measurement of standby power)
    • EN 50564:2011 – Electrical and electronic household and office equipment (measurement of low power consumption)

    In this video, application engineer Kourtney Morrison demonstrates how to use the software for easy standby power measurement.

    概览:

    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.
