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.

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.

More than a test tool 

Typically, a portable scope or test tool is used by an engineer to diagnose faults on a production line in real-time, or to carry out tests in a workshop. But how can faults be detected and diagnosed when they are intermittent and the engineer needs to be somewhere else? On the other hand, a portable data logger can capture lots of data, including the faults over a period of time, but requires the data to be searched and analysed later to make sense of it.

The WTViewerE is a powerful software that supports remote analysis and control of multichannel measurements from the WT series of Yokogawa power analyzers. In addition to real-time control of remote measurements in multiple formats and customizable layouts, the latest version of the software allows any 4 Yokogawa power analyzers regardless of configuration to be synchronized for multi-unit measurements.  This allows for sophisticated computations for larger applications that may need more than one power analyzer.

    Overview:

    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.

    Overview:

    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.
