Global warming has lead to a charge for more 'green' energy solutions, including renewable energy, which has a lesser degree of impact on the environment. Continued research has made renewable energy more affordable today. Wind energy, photovoltaics, ethanol fuel options are all types of desirable alternative energy sources, however, there is still a great deal of research to be done to maximize the cost-effectiveness of these options. Yokogawa, dedicated to protecting the global environment, is eager to support these channels for optimizing fuel efficiencies and support our customers who make it their priority to do so, as well. Our high quality, innovative measuring units can support your efforts in emerging markets.
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.
What is a Power Analyzer? Power analyzers and power meters measure electrical power in devices that generate, transform, or consume electricity.
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.
Measuring Conversion Efficiency of Power Conditioner
In this application note you will learn when and how to use different methods to connect a current transformer to a power analyzer.
The DL850 can take engineers to a new level of efficiency in the development of everything from green devices to complex advanced 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.
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 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.
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.
S.E.A. is a manufacturer of oil-cooled, air-cooled, and cast resin transformers that are used globally in power-transmission and distribution networks, railway infrastructures, factories, and for industrial equipment. S.E.A. products are high-value assets expected to provide a return over decades. Quality, durability, safety, and reliable performance are therefore the key characteristics that customers are looking for when they specify a new transformer or reactor.
AC Kinetics was challenged by Georgia Pacific to develop an algorithm to optimize the operation of large AC induction motors by 10%. To test their algorithm on a motor drive, they needed to demonstrate repeatable measurements in a real world application.
The current sensor element for the Yokogawa Test&Measurement WT5000 Precision Power Analyzer is ideal for applications requiring a current transformer for high-current measurements. The internal DC power supply simplifies preparations before measurement, requiring only a connecting cable and eliminating the external power supply.
The WT5000, an industry-leading power analyzer, features seven field-removeable elements, 10 MS/s, 1 MHz power bandwidth, 18-bit resolution, and 0.03% basic power accuracy. 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.
In this video we review the major features of the DL350 showcasing its portability, functionality, and operability. This device features battery power, 18 signal conditioning input modules, and touchscreen access to enhanced triggers, math, and analysis.
