The Renewable Ecosystem & Distributed Energy Resources (DER)
Whether generating power or consuming it, there is a universal need to analyze power, efficiency, and meet compliance standards. Yokogawa has unique and powerful analysis solutions to address these needs.
Electric power conversion adapts electrical energy for specific applications. Devices like inverters, rectifiers, and transformers facilitate this process but introduce losses and power quality issues. Accurate characterization of power electronics requires high-precision, traceable measurement instruments.
Energy efficiency measurements are best made with a precision power analyzer, while transient capture can be achieved with a variety of waveform measuring instruments. Traceable measurements ensures Power compliance ensures a product meets industry standards as verified by traceable measurements.
When fractions of a percent matter
This paper explains power efficiency and its relationship with power quality, educates readers on causes and types of power quality issues, and explains various efficiency measurements.
When you need to investigate
This paper provides a guide to basic electric power measurements, addressing the complexities of AC power, including distorted waveforms, fluctuating power factors, and multi-phase techniques.
When you need to comply
Power compliance refers to meeting industry standards and regulations. Selecting the proper instrument is a key determining factor. This application note provides guidance in choosing the right instrument.
Maximum power point tracking (MPPT) charge controllers play a crucial role in the optimization of renewable energy system efficiency and performance. Through dynamic tracking of a renewable energy source’s maximum power point, an MPPT controller enables more efficient energy harvesting, faster charging, and adaptability to changing environmental conditions.
Wind power is a renewable energy source that is being aggressively promoted (particularly in Europe) in order to reduce emissions of the greenhouse gasses that are responsible for global warming
Measuring transformer loss helps ensure safer operation and optimizes delivery of electricity. During testing, low power factor signifies high core losses and requires specialty instruments to more accurately measure power.

How-tos
This video demonstrates how to test to an IEC standard (IEC 61000) using a Yokogawa Test&Measurement WT5000 Precision Power Analyzer and the harmonic flicker testing software. The software automates the process of judging if the device under test is compliant with the chosen standard and allows you to output the necessary test reports for your records.
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.
