This newest Electrical Building Design Show explores the topic of time-current curves; an illustration of how long it takes for a breaker or fuse to trip at a given current. This installment explores time-current curves from our point of view as software developers rather than the perspective of electrical engineers. Over time, we have had to review a lot of time-current curves to have our software function properly, and we want to share the information we learned about them.
Highlights explored in the video include:
- Thermal Magnetic Curves: We review the three curve shapes and look at how they are adjusted by the breaker settings.
- Electronic Curves: We look at how these curves are loaded into software for use.
- Fuse Curves: We explore the specific parts of the curves that are used in arc-flash calculations.
- And more…
The Bottom Line:
Time-current curves are important tools for electrical engineers, especially for selective coordination and arc flash analysis. However, it is essential to remember that these curves often come from analog sources and may not have the precision that is expected from digital data.
At Design Master, our approach is to develop simple, easy-to-use software like ElectroBIM that follows necessary standards without adding unnecessary complexity.
