Medición de tensión, corriente y temperatura para la fuente de alimentación de corriente continua

Para la medición fiable y precisa de la tensión y la corriente en instalaciones de corriente continua, desde hace décadas Knick suministra transmisores con aislamiento galvánico. Durante este tiempo, la empresa se ha convertido en el líder mundial en este sector. Por este motivo, Knick también es el primer socio para proveedores y operadores de instalaciones de corriente continua cuando se trata de afrontar retos técnicos especiales, por ejemplo, opciones de supervisión del desgaste para el mantenimiento preventivo.

Key Requirements

¿Por qué Knick?
Los dispositivos de protección en centrales transformadoras deben medir la corriente y la tensión con el fin de ejecutar algoritmos para la detección de cortocircuitos. Para ello, se requieren transformadores de medida de alta tensión que miden de forma rápida y precisa, y que al mismo tiempo soportan cargas elevadas. Además, deben soportar tensiones entre 750 y 3000 V CC, incluyendo sobretensiones transitorias, por ejemplo, durante la recuperación de energía en el frenado de los trenes. En estas aplicaciones de alta tensión, la protección de las personas y los dispositivos es fundamental. Por consiguiente, el gran aislamiento galvánico de los dispositivos de Knick es un factor importante a la hora de elegir los transformadores de medida.
