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.
How can I capture data from motion sensors synchronized with other analog data? The Yokogawa ScopeCorder series of instruments feature input modules and functions to make this possible.
How to use built-in calculations to analyze motor rotor position and find the relative angle between the rotor and sensors such as encoders or resolvers.
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.
The DL850 can take engineers to a new level of efficiency in the development of everything from green devices to complex advanced systems.
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.
The request for lower uncertainties in power measurements are increasing,especially in the transformer industries. Their role is to ensure that the electricity is distributed in an efficient and reliable way.
This white paper describes the WT1600 precision power analyzer, a model that has been discontinued and replaced with the WT1800E. Please visit the WT1800E product page for more information regarding the WT1800E.
We have developed the WT1600, a high-precision, wide-bandwidth power meter. The WT1600 can measure DC and AC signals from 0.5 Hz to 1 MHz with a basic power accuracy of 0.1%. With the maximum of six input elements installed, a single WT1600 can measure the efficiency of a three-phase inverter. In addition to the functions of conventional power meters, it has wider ranges and various functions including waveform display. This paper gives an outline of the WT1600.
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 accuracy of a measurement instrument varies with the range over which a reading is measured.
But what if different manufacturers specify this range differently in their instruments?
This article explores the impact of range definitions on measurement accuracy and how one can be mindful when comparing accuracy across instruments.
