Yokogawa is the world’s leading manufacturer of power analyzers, devices that measure electrical power characteristics of devices that generate, transform, or consume electricity. Also called power meters or wattmeters, these devices measure parameters such as true power (watts), power factor, harmonics and efficiency in inverters, motor drives, lighting, home appliances, office equipment, power supplies, industrial machinery and other devices. Power analyzers also enable engineers to minimize energy loss in power electronics such as inverters, motors, lighting circuits, and power supplies.
A Digital Power Analyzer is an instrument for research & development, design validation, and manufacturing test used to accurately measure electrical power characteristics.
Yokogawa's Power Analyzer software manages numeric, waveform, and harmonic data measurements. It enables data transfer and instrument configuration for your computer.
Accessories for digital power analyzers include various voltage and current transformers, clamp-on current probes, and a selection of test leads.
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.
The PX8000 is the world's first precision power scope, bringing oscilloscope-style time-based measurement to the world of power analyzers. With up to four channels, it can perform standard multi-phase power measurements. These measurements exist alongside oscilloscope-specific features such as cursor-based specific time period measurements to enable analysis of waveforms with transient components.

Energy consumption in standby and low-power mode has been an important issue. This article shows the need to ensure accuracy in power measurement, especially at high crest factors and low power factors.
The need for accurate and reliable power measurement is greater than ever before. As the demands of society and its reliance on advanced technology continue to grow, so energy consumption is increasing at a rate that is unsustainable without a significant shift to alternative energy sources - which themselves require the use of new power electronic technology in the form of high-frequency inverters.
After a disastrous 2009, the large publicly held test companies enjoyed booming business in 2010.
Power measurements get harder every day. Because of demands for power efficiency, engineers need to prove that their designs meet tough specifications for power consumption. Because of that, Yokogawa has improved accuracy of it's top-line AC power analyzer.
RTCA Inc, (Radio Technical Commission for Aeronautics) Washington, DC, is a non-profit corporation that functions as a Federal Advisory Committee to the Federal Aviation Administration (FAA). Its recommendations serve as the basis for policy, program and regulatory decisions. Sub-committee SC-135 produces the RTCA/DO-160E document titled Environmental Conditions and Test Procedures for Airborne Equipment. This document defines the test conditions and procedures for testing airborne equipment and is the standard by which Boeing, Airbus and other manufacturers require avionic components and sub-systems to be tested.
Improving and optimizing electric motor performance and efficiency depends on understanding how electric current is measured.
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.
This short informative Webinar covers new measurement techniques and solutions for making precision power measurements to improve product performance and efficiency designs.
Yokogawa and e-Drive Magazine are bringing you a one hour webinar on November 17, 2011 at 11:00am EST. This seminar will provide attendees with a three step process for making precision electrical and mechanical power measurements on AC motors and variable speed drive systems in order to measure and calculate the system power efficiency.
In this webinar, Yokogawa's Bill Gatheridge educates and provides attendees with practical solutions for making precision electrical power measurements. He also covers the use of a digital power analyzer, as well as the DO's and DON'Ts of using a digital oscilloscope for making electrical power measurements.
In this one-hour webinar, you will learn a three-step process for a complete electrical test of an AC motor & variable-speed drive system.
In this one-hour webinar you will learn about voltage and current harmonics. Specifically, you will learn how to measure and characterize this type of waveform distortion, and how it can affect your power system.
