Trusted Solutions for Power Quality, Energy Efficiency, and Power Compliance

 

Global environmental market forces considerably impact how products are manufactured. Affordable, clean energy is a sustainable development goal intended to drive better efficiency.

In an effort to save energy through efficiency gains, those gains are often counteracted with power quality impacts due to the growing use of non-linear devices in product designs. Minimizing power quality issues, such as harmonics, while improving efficiency can help lower worldwide dependency on energy, while meeting the Department of Energy’s (DOE) efficiency compliance goals.

Power Compliance | Power Quality | Energy Efficiency | Yokogawa Test&Measurement

Whether a product generates power or consumes it, the measurement of energy efficiency, power quality, and power compliance is a universal requirement. Yokogawa Test&Measurement has unique and powerful analysis solutions to address these power needs.

Choosing the Right Instrument for Power Quality and Energy Efficiency - Power Compliance, Efficiency, and Harmonics Tests
Application Note

Power quality, power efficiency, and power compliance are terms often used interchangeably, but actually have different meanings depending on the industry being referenced. Three variables to consider when choosing the best instrument for power compliance and power quality measurements are measurement type, measurement standard, and instrument type. This application note defines these variables and provides guidance to make the most accurate power quality, efficiency, or compliance measurement.

Power Measurement Challenge | Yokogawa Test&Measurement

The non-linear semiconductors used in inverters to transform DC power to AC power inherently generate harmonics and noise, originating in the high dv/dt and di/dt semiconductor switching transients. It is important to measure energy efficiency and monitor the power quality to determine if levels are compliant within acceptable limits.

Energy Measurement Instruments and Solutions | Yokogawa Test&Measurement

The best instruments to perform these measurements can vary depending on the measurement type and measurement points. Energy efficiency measurements are best made with a precision power analyzer, but transient waveform capture is often better achieved with a Power Scope. Power compliance ensures a product meets industry standards and that the proper solution is specific to the standard being tested.

"They just work!"
When I started with my company almost 20 years ago, Yokogawa Test&Measurement instruments were already in use and the engineers had no intention of switching. In fact, we still routinely use some of the older instruments because, well, they just work! The equipment doesn't really become obsolete, and they support their instruments as long as is feasible, which ultimately saves us money. Even so, as things change in our industry Yokogawa adjusts to meet those changes. From our sales representative through technical support and more, I can count on the Yokogawa team to really listen and work with us to provide a specific solution for unique problems.

IEC62301 Standards Testing for Standby Power Measurement??
Application Note

Energy consumption in low-power and standby modes is recognized as an important issue due to increased awareness that energy resources are becoming more limited and the demand for energy-saving household electrical appliances continues to grow. Internationally recognized standard IEC62301 Ed2.0 (2011)defines standby mode as the lowest energy consumption of an appliance not performing its main function, when connected to the mains, and also defines the test methods and requirements for both the mains supply and the test equipment.

High Precision Measurement of Standby Power
Application Note

Standby power consumption of an individual electric appliance is small, but the cumulative standby power consumption of all appliances in a household accounts for a sizeable percentage of that household's annual power consumption. Standards for power reduction such as IEC 62301:2011 (Ed. 2.0), ErP Directive, and Energy Star specify how to measure power consumption in standby power mode and requires highly-accurate power measurement. This document introduces four methods and accompanying challenges for reducing standby power, and key points of high accuracy power measurement.

How to Make Successful Harmonic Measurements
Application Note

Efficiency and power quality standards for appliances and equipment used in residential and commercial buildings are designed to reduce energy costs. Generating reliable power is paramount in critical generation systems such as those in aerospace, military, and standby power applications. Power standards for generation systems typically focus on ensuring robust power networks. The efficiency and reliability of power networks are maximized by increasing the power quality of the system. Harmonic content is a key contributor to low power quality, and agency standards are written to ensure manufacturers take action to measure and control harmonics.

Harmonic and Voltage Fluctuation/Flicker Measurement According to IEC61000
Application Note

The 50/60Hz commercial power supply waveform is a sine wave. When a device such as an inverter-driven motor or switching power supply is connected, a frequency component that is an integer multiple of the 50Hz/60H signal is generated, distorting the commercial power supply. This application note describes the IEC61000 harmonics and flicker solution.

Capture and Measure Transient Phenomena on Power Signals with a Power Scope
Video

In several applications, especially those testing AC power to a standard such as IEC61000-3-11, voltage and current signals must be monitored for 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 properly 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:

We developed an algorithm to optimize induction motor operation and produce an average power consumption savings of at least 10%. To demonstrate our algorithm’s effectiveness, we needed a proven and verified system that would give these results credibility. The solution provided by Yokogawa Test&Measurement enabled us to monitor and refine our algorithm using real-time speed, power, and temperature readings – data that would normally be incredibly difficult to accurately obtain. Having these real-world results that demonstrate the effectiveness of our algorithm means we can be more efficient with our own customers. —Neil Singer, President, AC Kinetics

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, compliance is an absolute requirement for entry into global markets. 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, learn to recognize and distinguish the critical difference between DFT and FFT, and discover important measurement tradeoffs across various test equipment.
