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.

横河新型示波功率仪PX8000产品介绍演示
The current sensor element for the Yokogawa Test&Measurement WT5000 Precision Power Analyzer is ideal for applications requiring a current transformer for high-current measurements. The internal DC power supply simplifies preparations before measurement, requiring only a connecting cable and eliminating the external power supply.
The WT5000, an industry-leading power analyzer, features seven field-removeable elements, 10 MS/s, 1 MHz power bandwidth, 18-bit resolution, and 0.03% basic power accuracy. Yokogawa Test&Measurement continues to innovate on the platform, enabling /D7 data streaming, /G7 harmonics, and flicker analysis.
The new current sensor element replaces the traditional current inputs and includes a sensor input terminal with integrated ±15V power supply, eliminating the need for an external power supply. The isolated voltage terminals remain the same as the 5A and 30A elements.
入门指南
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.
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.
