What is a Power Analyzer? Power analyzers and power meters measure electrical power in devices that generate, transform, or consume electricity.
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.
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.
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.
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.

Evaluation of high efficiency motors in large air heaters
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.

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This white paper describes the WT1800, a precision power analyzer that has been replaced by the WT1800E, a unit with numerous improvements including better accuracy.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.
The objective of this paper is to show the close relationship between efficiency and power quality, and provide education on the causes of power quality, types of power quality issues, and provide guidance on measurement considerations.
This article looks at some of the factors that can affect the accuracy of power measurements and shows how users can address the challenges presented by the need for accurate energy-efficiency testing.
Laval University is a research institution world renowned for optics and photonics technology research and training, and are the founders of The Center for Optics, Photonics, and Lasers (COPL).
The university's researchers needed a faster and more efficient and practical solution to measure the spectral performance of lasers and optics beyond traditional telecom wavelengths. To achieve this, they contacted Yokogawa Test&Measurement and collaborated to develop a breakthrough grating-based optical spectrum analyzer that could cover MWIR wavelengths up to 5.5 um.

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.
Using the DL350 Memory Recorder Mode Easy Setup, combined with a 16-channel thermocouple input, it's easy to record hours, days, or weeks of data with a few simple settings.

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, harmonics lead to reduced system capacity and increased maintenance, downtimes, and costs. 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.
