Yokogawa has been providing instrumental service to industry giants as part of our core business since our early beginnings. We continue to provide critical tools such as the WT3000E and the SL1000 and a wide variety of precision power analyzers to industry leaders for use in compliance testing. Yokogawa is dedicated to protecting the global environment. One way we do this is through our partnerships with industry leaders who are also dedicated to the global environment and providing channels for superior energy efficiency. Yokogawa designs products specifically to test such industry standards as Energy Star and UL.

Using the OR trigger and Dual Capture, it is easy to trap and record failure conditions on electrical harnessses (wiring interconnects) over a long duration test.
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.

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.
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 white paper discusses the basics of AC, DC, and power measurements, and a three-step process for making precision electrical and mechanical power measurements on a variety of motors and variable frequency drive (VFD) systems. It is also shown how these measurements are used to calculate the energy efficiency for motor and drive systems.
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.
