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.

Overview:

What is a Power Analyzer? Power analyzers and power meters measure electrical power in devices that generate, transform, or consume electricity.

Overview:

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.

How-tos

    Overview:

    A demonstration reading a 4 - 20 mA transducer into an analog channel on the DL350 Portable ScopeCorder.

    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:

    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. 

    Overview:

    CAN Bus communication is widely used in the transportation industry where reliable transmission of data is paramount. Monitoring and recording these communications can be easier when using the proper instruments. In this video, a Yokogawa Test&Measurement Applications Engineer demonstrates how to setup the DL950 ScopeCorder to read the temperature of a motor drive alongside its voltage and current output.

Webinars

    Overview:

    Why should you be concerned with your product’s power system voltage and current harmonics?

    From an engineering perspective, harmonics produce excessive heat in equipment that causes significant damage and results in inefficient operation. From a business perspective, harmonics lead to reduced system capacity and increased maintenance, downtimes, and costs. To minimize or eliminate these issues and establish acceptable levels of harmonics, numerous power quality standards with specifications and limits for harmonic distortion, such as IEEE 519-2014 and IEC61000-3-2, have been introduced.

    During this webinar, attendees will:

    • Gain knowledge on the inner workings of harmonics
    • Learn best practices for accurately measuring harmonics
    • Recognize and distinguish the critical difference between DFT and FFT
    • Discover important measurement tradeoffs across various test equipment
