Measuring true power is more than multiplying voltage and current. Advances in complex power electronics and energy efficiency create measurement challenges that can confound even the most experienced engineers.
Unlike data acquisition and oscilloscope-based power measurement tools, power analyzers are purpose-built to guarantee measurement accuracy when testing devices that generate, transform, or consume electricity.
Yokogawa, the world's leading supplier of electrical power analyzers, provides solutions for testing power electronics, inverters, motors and drives, lighting, home appliances, office equipment, power supplies, industrial machinery and more.
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.
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.
Maximum torque per ampere (MTPA) is an optimization strategy for the control of electric motors and drives that employ field-oriented control (FOC), particularly with electric vehicles (EVs) and industrial automation applications. The goal of MTPA is to achieve the maximum possible torque output from a motor for a given current input.

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.
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.
Standards driving energy efficiency classifications are a driving force behind the development of the next generation of motor and drive technologies. Learn more here.
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.
In recent years, there has been an increased emphasis on energy efficiency in industrial systems, resulting in more penetration of power electronics in equipment such as inverters and motor drives.
Many industry trends are conspiring to make power analysis an important consideration for designers. The New Electronics editor takes a look at this expanding arena by talking to Hafeez Najumudeen of Yokogawa.

Yokogawa Test&Measurement continues to innovate on the platform, enabling /D7 data streaming, /G7 harmonics, and flicker analysis.
The new current sensor element replaces the traditional current inputs and includes a sensor input terminal with integrated ±15V power supply, eliminating the need for an external power supply. The isolated voltage terminals remain the same as the 5A and 30A elements.
Test and measurement engineering work groups can have differing priorities and requirements, which often results in multiple instrumentation systems and data file formats, as well as incompatible reporting. This lack of effective communication between groups and instruments causes decreased efficiency and quality and increased spending and time to market. Unify test and measurement instrumentation, software, and data across engineering teams with a suite of solutions that caters to the different needs of engineering work groups, including accurate power data, fast sampling rates, long recordings of multiple different input types, and insights into waveform data.
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.
Having multiple memory options allows engineering groups to optimize how data is stored, no matter if you need to record for a long time at slower sampling rates, do a fast capture at high sampling rates, or anything in between.
The Yokogawa Test&Measurement DL950 ScopeCorder operates as an oscilloscope and incorporates the ability to record data for long periods of time like a data acquisition recorder. There are four memory types on the DL950 ScopeCorder: internal memory, solid state drive, flash memory, and PC storage through the IS8000 Integrated Test and Measurement Software Platform. This videos talks about the advantages of each of these and how to pick the best data recording method for you.
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.
