O aquecimento global tem nos conduzido a uma cobrança por implementações de soluções energéticas “limpas”, incluindo energias renováveis que têm um menor impacto ao meio ambiente. Pesquisas continuadas tornaram a energia renovável mais acessível nos dias de hoje.
Energia eólica, energia fotovoltaica e álcool combustível são opções desejáveis de fontes de energia alternativas, no entanto, ainda há uma grande quantidade de pesquisas a serem feitas para maximizar a relação custo-benefício dessas opções. A Yokogawa, dedicada a proteger o ambiente global, está empenhada em apoiar estes canais para otimizar a eficiência dessas fontes de energia e apoiar nossos clientes que também tem a prioridade de fazê-lo. Os oscilógrafos DL950 e os analisadores de potência WT1800E e WT5000 são exemplos de instrumentos que lhes permitirão gerenciar estes esforços. O oscilógrafo DL950 consiste em um misto de sistema de aquisição de dados e osciloscópio com canais isolados, e que proporciona uma gama enorme de aplicações por sua flexibilidade, rápida velocidade de aquisição e capacidade de captura de dados. Os analisadores de potência WT1800E e WT5000 permitem a avaliação de rendimento de conversores e geradores, com alto desempenho, precisão e confiabilidade.
Dentre as principais aplicações neste segmento destacam-se:
- Captura e avaliação de transientes elétricos: oscilógrafos da linha DL e analisadores de qualidade de energia CW500;
- Avaliação e comissionamento de geradores: analisadores de potência série WT e oscilógrafos série DL950;
- Análise de rendimento de inversores eólicos, fotovoltaicos e geradores: analisadores de potência série WT e PX8000, oscilógrafos série DL950;
- Manutenção preditiva e análises diversas: multímetros digitais TY720, megôhmetros, calibradores e osciloscópios digitais série DLM.
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.
Visão geral do produto
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
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.
