In the test of new washing machine, voltage, current, power, and the control signal on the time control panel need to be recorded.
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.

If a product uses power, then power consumption and power quality measurements must be made as part of product design and test. These measurements are essential to optimize product design, comply with standards and provide nameplate information to customers.
This article will discuss best practices for making these measurements, starting with power measurement basics and proceeding to the types of instruments and associated components typically used to make measurements. The article will conclude with real-world examples, which apply the information imparted earlier in the article to solve practical measurement problems. Although most of us have been exposed to basic power measurement equations, a primer is helpful to summarize this information and to show how it applies to product design and test.
One of the main responsibilities of engineers and technicians is data analysis, and this article will show how multi-touch technologies can be used to improve the performance of this and other related tasks.
In this application note you will learn when and how to use different methods to connect a current transformer to a power analyzer.
This white paper describes the WT1800, a precision power analyzer that has been replaced by the WT1800E, a unit with numerous improvements including better accuracy. Please visit the WT1800E product page to learn more about the WT1800E.
To keep pace with the increasing speed of switching devices in inverters, Yokogawa has developed the WT1800 precision power analyzer with 10 times faster sampling speed and 5 times wider frequency bandwidth compared with previous models. Its basic accuracy is 0.15% and the frequency bandwidth of voltage and current is 0.1 Hz to 5 MHz (-3 dB, Typical) including the DC component. With up to six inputs, a single WT1800 unit can measure the efficiency of three-phase inverters. In addition, the high-speed data capturing mode allows the WT1800 to measure transient power. This paper describes the high-speed, real-time power measurement technologies underlying these functions.
This white paper describes the WT1600 precision power analyzer, a model that has been discontinued and replaced with the WT1800E. Please visit the WT1800E product page for more information regarding the WT1800E.
We have developed the WT1600, a high-precision, wide-bandwidth power meter. The WT1600 can measure DC and AC signals from 0.5 Hz to 1 MHz with a basic power accuracy of 0.1%. With the maximum of six input elements installed, a single WT1600 can measure the efficiency of a three-phase inverter. In addition to the functions of conventional power meters, it has wider ranges and various functions including waveform display. This paper gives an outline of the WT1600.
The accuracy of a measurement instrument varies with the range over which a reading is measured.
But what if different manufacturers specify this range differently in their instruments?
This article explores the impact of range definitions on measurement accuracy and how one can be mindful when comparing accuracy across instruments.
Are you achieving the levels of accuracy you need?
This article outlines the top reasons for inaccuracies in power measurements and how to tackle them.

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.
