HARTING: Current Measurement

Whether for transportation or industrial applications: the ability to quickly and accurately detect current is required in order to precisely control power electronics systems such as frequency converters, traction converters, UPS systems or welding systems. Current sensors are electromechanical components which deliver a precise, real-time representation of the input and output currents. The measuring signals are then used (e.g. in frequency converters) for precisely controlling the power semiconductors and for monitoring performance and functionality.

 

 

 

Rockwell Automation: Short-Circuit Current Ratings

Rockwell Automation: Short-Circuit Current Ratings

What is short-circuit current rating (SCCR)? The maximum available short-circuit current an electrical component can sustain without the occurrence of excessive damage when protected with an overcurrent protective device. Determining the SCCR of a complete industrial control panel or control switchgear can be challenging, especially if proper considerations are not made during the initial stages of the component selection process.
