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.
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.
Are you achieving the levels of accuracy you need?

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.

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.
Using the DL350 Memory Recorder Mode Easy Setup, combined with a 16-channel thermocouple input, it's easy to record hours, days, or weeks of data with a few simple settings.
By using the Yokogawa WT5000 Precision Power Analyzer, Società Elettromeccanica Arzignanese S.p.A (SEA), an Italian manufacturer of power transformer and reactors with a worldwide reputation for engineering excellence and high production quality, is able to closely match the efficiency performance guarantee that it makes to a customer, with the actual performance of the transformer.
