1. 86A-11 Effects of inlet temperature, electric field strength, and composition on the occurrence of arcing during ohmic heating
- ift.confex.com
- Effects of inlet temperature, electric field strength, and composition on the occurrence of arcing during ohmic heating .
- Arcing phenomena on carbon electrode surfaces in ohmic heating were investigated with isolated soy protein and modified starch solutions. ... Arcing time increased with decreasing electric field strength or inlet temperature at the same protein content, and decreased with increasing protein content at the same electric field strength and inlet temperature. ...
- The objective was to study the effect of temperature, electric field strength, current density, and composition on the occurrence of arcing during ohmic heating.
- The parameters were varied in successive experiments until arcing was observed. The time duration from the application of voltage to the arcing point was recorded. ... An arcing diagram was plotted to present results.
- Arcing diagrams showed that the higher the temperature, the lower the electric field strength needed for arcing. The diagrams roughly demarcate three areas: arcing zone, safety zone, and critical zone. At the same operating condition, the higher the protein content, the easier the onset of arcing. At the same electric field strength, the arcing time exponentially decreased with increasing inlet temperature of sample. ...
- The relationship between inlet temperature, electric field strength, protein/starch content, and arcing occurrence can be used to guide food processors to operate an ohmic heating process without arcing. ...
2. Prediction of the Erosion of Arcing Contacts in High-Voltage Circuit Breakers
- www01.se.abb.com
- Prediction of the Erosion of Arcing Contacts in High-Voltage Circuit Breakers .
- The erosion of arcing contacts and thus the changing of the contact geometry is an important factor in the lifetime of a circuit breaker. It is known that the erosion depends at least on parameters like the arcing current-amplitude, total charge and contact material properties. But up to now there is nNo theory available for reliable prediction of arcing contact erosion.
- Based on experimental results, a theory for description of the erosion of arcing contacts was derived. The experiments have been carried out in a SF6 self-blast circuit breaker test device with conventional high-voltage circuit breaker contacts at current amplitude up to 45 kA RMS and arcing time up to 15 ms.
- This theory is in good correlation to the experimental results and explains that the specific erosion scales with current, polarity and the arcing time.

- Experimental Investigation on the Erosion of Arcing Contacts in High-Voltage Circuit Breakers.
- The erosion of arcing contacts and thus the changing of the contact geometry is a main factor that determines the lifetime of a circuit breaker. It is known that the erosion depends at least on parameters like the arcing current-amplitude, total charge and contact material properties. The aim of this work is to achieve a more precise prediction of the mass losses and the geometry changes of arcing contacts in high-voltage circuit breakers, considering the contact polarity, the arcing time and materials from different contact suppliers.
- 50 kA and arcing times between 5 ms and 17 ms. ... It turned out that the ā best-fitā scaling of the specific erosion is reached when the current, polarity and the arcing time is considered. ...
