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 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.
Test and measurement engineering work groups can have differing priorities and requirements, which often results in multiple instrumentation systems and data file formats, as well as incompatible reporting. This lack of effective communication between groups and instruments causes decreased efficiency and quality and increased spending and time to market. Unify test and measurement instrumentation, software, and data across engineering teams with a suite of solutions that caters to the different needs of engineering work groups, including accurate power data, fast sampling rates, long recordings of multiple different input types, and insights into waveform data.

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.
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.
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.
