In this application note you will learn when and how to use different methods to connect a current transformer to a power analyzer.

Visão Geral:

With the increased demand in electric-hybrid vehicles, the electromechanical designs of in-vehicle systems are becoming more sophisticated and there has been a demand shift towards high efficiency brushless direct current motor (BLDC) implementation. Think of motorized seat adjustment, electric window, power steering, HVAC fans, pumps, etc. In many of these systems various types of motors are used as actuators; more specifically, 3-phase BLDC motors are gaining popularity as they provide these important advantages:

  • Improved speed vs torque characteristics
  • High dynamic response
  • High efficiency
  • Extended speed ranges
  • Long operation life

    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.

    Visão Geral:

    Test and measurement engineering work groups can have differing priorities and requirements, which often results in multiple instrumentation systems and data file formats, as well as incompatible reporting. This lack of effective communication between groups and instruments causes decreased efficiency and quality and increased spending and time to market. Unify test and measurement instrumentation, software, and data across engineering teams with a suite of solutions that caters to the different needs of engineering work groups, including accurate power data, fast sampling rates, long recordings of multiple different input types, and insights into waveform data.

How-tos

    Visão Geral:

    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.

Webinars

    Visão Geral:

    While DC power measurements are relatively straight forward, AC power measurements that include distorted waveforms, varying power factors, and multiple phases can add complexity to an otherwise simple measurement. During this webinar, we cover multiple fundamentals of power measurement.

    Key topics include:

    • Multi-phase measurements
    • Measurement techniques
    • Measurement applications
    • Real-world examples and more
