Over-Current Protection Assembly
US 20170062155
Gaseous wiping or vacuum butt contact switch that commutate current from bridging contacts to number of contacts arranged in series. On closing the many series contact touch first (minimizing the weld damage from pre-arcing). Without the potential weld condition, the high energy operator mass, high wipe travel and long linkages, the contact movement of US20170062155 will have a high accuracy and repeatability of contact part using a regulated supply.

On closing the many series contact touch first (minimizing the weld damage from pre-arcing). Without the potential weld condition, the high energy operator mass, high wipe travel and long linkages, the contact movement of US20170062155 will have a high accuracy and repeatability of contact part using a regulated supply.
The precision of the contact parting, low and consistent vapor pressures between contacts and low stray capacitance effect, means that external grading capacitors to maintain the interrupting rating can be eliminated.
With switch openings in the +/- 1 ms range and +/- 1 ms signaling of traveling wave technology means the peak currents are reduced by up to 70%, and the total rms arcing reduced to less than 5% of that used conventional technology. Total interrupting time 1/2 cycle +1 ms. Total arcing time < 2 ms on each synchronized interrupter.
Suitable for high endurance on low voltage direct current interruption, and advancing the current zero for alternating current systems (arc flash mitigation). Designed to mitigate welding behavior, current chopping, post zero current, re-ignition, and re-strike phenomena that exist with single butt vacuum contacts. The compact design, and lower arcing times means that SF6 volumes can be minimized by up to 95%. Switch is totally sealed for life to prevent a yearly designed leakage rate. At end of life, all the SF6 used in the switch will be recovered. The precision motion of low energy operator and contact travel makes it highly suitable for synchronized high voltage switching.

Dr. Foss - Free Shear Flow Lab and Ti Tau Sigma honory adviser
Programming Engineer and Laboratory Assistant
-Recruited by Dr. John Foss (https://www.egr.msu.edu/people/profile/foss) for employment in his laboratory. Modeled air fluid flow across surfaces of wind tunnel at the Free Shear Flow laboratory at Michigan State University. For use with equipment electrical interruption and gas flows.

Modeled air fluid flow across surfaces of wind tunnel at the Free Shear Flow laboratory at Michigan State University. For use with equipment electrical interruption and gas flows. While I liked the numbers associated with computer science, math, mechanical and engineering writing modeling code - would not be my final career. I wanted to be a engineering generalist - the great everything and best at nothing. Colors and visualizing decaying graphical mathematics was my engineering gift, but I saw no value in it - despite recognizing the Apple graphical interface was far superior than IBM’s PC linked to the mainframe.

Modeled electrical and mechanical systems . Program was Boeing NASA funded and purchased by GM, state of art 3 D modeling existed in the early 80’s. Unable to grasp symmetrical equations for my electrical engineering, I discovered the accuracy of the algebraic method using the most powerful IBM mainframe available. My failure of symmetrical equations had been solved and due to uncertainty of how my methods would be received- I told the my professors I solved it. Not being aware of my access nor the program the Professors were mystified. After writing a 10 page paper on the topics, the Professor called my computer, Physics and EE instructors. While I only marginally made it to Pi Tau Sigma honors society, after reviewing the qualification and interviewing the professors - Dr. Foss attempted a second time to higher me back, which briefly did to assist Dr. Foss - who has been instrumental to my development, even up until 2011 when he started to move towards retirement.
