    How do I determine busbar junction resistance?

    Very simple! Run 100Amps DC from a current generator and read the voltage drop on the contact. The higher the temperature the higher the drop voltage. That means resistance is not constant!!! Traian

    DC Knife Switch basic design

    Please let me know if there are any engineering books with some calculations regarding how to design knife switches or other power switches (800A to 3000A, 60v to 240vDC). I need basic formulas to design as small as possible switches. Traian
