De nombreux instruments de mesure électrique DC fabriqués par Knick comprennent une alimentation universelle, ou à large spectre. Cela signifie qu’ils fonctionnent avec un spectre relativement large de tension, par exemple 20…253 V, AC ou DC.
L’ampleur de la dégradation photovoltaïque (PV) est un élément important à prendre en compte pour la conception et l’installation de systèmes. Avec le temps, des facteurs tels que la météo et l’exposition aux UV contribuent au déclin de la performance des cellules solaires. En comprenant mieux les effets de la dégradation et des contributeurs, les améliorations technologiques et de sauvegarde peuvent potentiellement être envisagées afin d’améliorer les performances.
Les transducteurs de tension de Knick permettent un contrôle réel aux applications de mesures électriques dans un vaste éventail de secteurs. Avec un grand nombre de solutions conçues pour les mesures et une isolation sécurisée de la tension DC jusqu’à 4800 V, et autres transducteurs qui proposent une conversion précise de tension AC d’entrée en sortie DC standard, Knick incarne la résolution de problèmes de 480 à 4800 volts !
Les transformateurs ont longtemps été considérés comme des composants importants des systèmes électriques. Il ne fait aucun doute que ces appareils sont essentiels lorsqu’il est nécessaire d’augmenter ou de diminuer la tension dans une optique de transmission ou de distribution du courant.
As electrification becomes more prevalent across many different classes and types of vehicles, the technology that drives its backbone of systems and components continues to advance. This is especially true with batteries, where gains in efficiency, size, charge time, and capacity seem to be ever moving.
Applications for DC electrical transducers are encountered often within the rail industry for measurement purposes. They are prevalent on both rolling stock and substation equipment dedicated to traction power. Information afforded by voltage and current measurements is often used for control, safety, and data collection.
Critical electrical measurement applications found within the rail transit industry require equipment that can keep up with the demands seen. Safety, precision, speed, and ease of use, are all important factors to consider when making component selection. Depending on the application, different factors might weigh heavier than others.
There are many systems where measurement of large DC currents are needed for performance and safety. Two examples are static excitation and rail traction power. These current measurements are often made by one of two main principles: shunt resistor with mV transducer or Hall effect feed-through sensor.
The reliable detection of short circuits and the proper handling of signal transmissions is not only important for smooth rail operations, but also for the safety of employees and passengers. Precision and reliability with voltage and current measurement, in addition to sound signal separation and conversion, are critical in ensuring this safety on both rail vehicles and in substations.
Failure of equipment on the plant floor can lead to considerable and costly disruption. For operators of power generation facilities, transport systems, chemical, pharmaceutical and other production plants, a continuous and reliable operation is of the utmost importance. Failures of components can put a halt to important processes, costing both money and time. Devices which rarely fail are critical to maximizing a plant’s uptime.
