An electrical appliance is an electrical device or instrument that performs a specific function for industrial or household use. Appliances can use current electricity and store electricity in batteries to convert it into other forms of energy such as heat, light, and movement.
In the test of new washing machine, voltage, current, power, and the control signal on the time control panel need to be recorded.
Detailed measurement methods, supply voltage settings, and others are specified for the harmonic/flicker standard test.
The accuracy of a measurement instrument varies with the range over which a reading is measured. Not all instrument manufacturers specify accuracy and ranges in the same manner. This article explores the impact of range definitions on measurement accuracy and how one can be mindful when comparing accuracy across instruments.
What is an Oscilloscope? Oscilloscopes, also called digital storage oscilloscopes (DSOs) or mixed signal oscilloscopes (MSOs), are common test instruments used to display, analyze, and troubleshoot electrical or physical signals.

What is a Power Analyzer? Power analyzers and power meters measure electrical power in devices that generate, transform, or consume electricity.
A ScopeCorder is a powerful portable data acquisition recorder that combines features of a multi-channel digital oscilloscope and a high-performance oscillographic recorder. As such, it can capture and analyze both short-term transient events and long-term trends for periods up to 200 days.

With increased focus on reducing energy consumption and compliance with efficiency standards, this app note provides an overview on the types of measurements needed for efficiency and power quality, and the instruments that take them.
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.

We developed an algorithm to optimize induction motor operation and produce an average power consumption savings of at least 10%. To demonstrate our algorithm’s effectiveness, we needed a proven and verified system that would give these results credibility. The solution provided by Yokogawa Test&Measurement enabled us to monitor and refine our algorithm using real-time speed, power, and temperature readings – data that would normally be incredibly difficult to accurately obtain. Having these real-world results that demonstrate the effectiveness of our algorithm means we can be more efficient with our own customers. —Neil Singer, President, AC Kinetics

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.

Why should you be concerned with your product’s power system voltage and current harmonics? From an engineering perspective, harmonics produce excessive heat in equipment that causes significant damage and results in inefficient operation. From a business perspective, compliance is an absolute requirement for entry into global markets. To minimize or eliminate these issues and establish acceptable levels of harmonics, numerous power quality standards with specifications and limits for harmonic distortion, such as IEEE 519-2014 and IEC61000-3-2, have been introduced. During this webinar, attendees will gain knowledge on the inner workings of harmonics, learn best practices for accurately measuring harmonics, learn to recognize and distinguish the critical difference between DFT and FFT, and discover important measurement tradeoffs across various test equipment.
While DC power measurements are relatively straight forward, AC power measurements that include distorted waveforms, varying power factors, and multiple phases can add complexity to an otherwise simple measurement. During this webinar, we cover multiple fundamentals of power measurement.
