BusBar Joint contact resistance

Hi,

Currently we are conducting the Busbar joint contact resistance test. I would like to get data for the standard or some kind of allowable resistance range in percentage of Ampere rating.

%Ir- micro ohms- joint lapping area.???

It is very simple. The measured contact resistance must be no more then the same length of busbar resistance.

If jointed busbars are with different longitudinal specific resistance, must be compared with higher one. The same length means distance between measuring points, which usually is a little more then length of contacting part.
