The Yokogawa CW500 is a portable power analyzer that logs transient power phenomena in addition to measuring single to three phase power.
Yokogawa's Power Analyzer software manages numeric, waveform, and harmonic data measurements. It enables data logging and instrument configuration from your computer.
Accessories for digital power analyzers include various voltage and current transformers, clamp-on current probes, and a selection of test leads.
- Regulate AC and DC with high-precision current transformers
- Current transformer meters from 60-5000 Amp peak
- Units with up to six CTs
In some power measurement applications, the current in the device under test is higher than what can be applied directly to the power analyzer current input terminals. Current transformers are used to step down high AC and DC currents to a lower level that can be measured directly by the power analyzer. These systems safely step down currents while preserving the highest accuracy.
This panel-mounted power meter and energy meter with a large, three-row LED display integrates all the measuring functions required for power management in locations such as factories and buildings into a single unit.

In this application note you will learn when and how to use different methods to connect a current transformer to a power analyzer.
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.
Measurement guidance related to field-oriented control (FOC) of electric motors with example use cases that illustrates how this is accomplished using a power analyzer and/or a ScopeCorder. Specifically addressed are direct and quadrature currents of a surface-mounted permanent magnet motor (SMPM) with field weakening applied. The techniques illustrated can also be applied to other FOC variables, algorithms, and motor technologies.
What is a Power Analyzer? Power analyzers and power meters measure electrical power in devices that generate, transform, or consume electricity.
This application note details the process for measuring and verifying proper motor function using a power analyzer, and how to troubleshoot common errors in the measured output.

Designing an instrumentation system for high current measurement requires careful consideration of the trade-offs associated with each type of sensing device. The purpose of this application note is to help engineers understand the sensing choices available and the corresponding trade-offs with each technology.
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 have developed the WT3000 Precision Power Analyzer, which features the world's highest measurement accuracy of ±0.02% of reading and a measurement bandwidth of 0.1 Hz to 1 MHz as well as DC signals.
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.
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.
Government agencies that define the standardization of energy efficiency metrics continue to be a driving force behind the development of the next generation electric vehicle powertrains. These metrics require manufacturers to have high confidence in their measurements and motivate the optimization of efficiency.

Yokogawa developed the PX8000 precision power scope, a high-accuracy power meter, which can measure reactor losses in inverters, motors and the like, by analyzing waveforms. The major specifications of the instrument are as follows: basic accuracy is 0.2%, voltage measurement bandwidth is DC and 0.1 Hz to 20 MHz (-3dB, typical), and current measurement bandwidth is DC and 0.1 Hz to 10 MHz (-3dB, typical). The PX8000 offers the functionality usually provided by a waveform measuring instrument, such as a variety of triggers, tracking, statistical processing, and waveform parameter calculation functions. Furthermore, to improve measurement accuracy at low power ratios this product comes with a de-skew function for correcting signal delays from the current sensor and a data latency adjustment function. This paper describes the PX8000, focusing on a newly developed element dedicated for power measurement and technology for phase correction.
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.
We have added a harmonics current/flicker measuring function to the WT3000 Precision Power Analyzer with world-leading accuracy of power measurement. We have also created PC software for harmonics current/flicker measurement. This PC software and the WT3000 comply with the IEC61000- 3-2 harmonics current standard and IEC61000-3-3 voltage fluctuation/flicker standard, thus enabling the electrical power, harmonics current and flicker of electrical equipment to be measured precisely with a single unit. This paper outlines the harmonics current standard and voltage change/flicker standard, along with the measurement principle and PC-based software of the WT3000.

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.
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.

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.
