Busbar Ductor Testing

Our company policy is to test each joint. His method won't show up any individual high joints.

Exactly

He's still at it now. Started at 10 ish

Modern Ductor tester, takes 10s for each test. All stored internally and can be downloaded to PC. Compared to the amount of faffing about making shorts, calculation and repositioning the shorts, I know what I would be doing. The only issue I ever found with busbars was over-torque, construction guys had been at it with their big-boy spanners and tightened the sections too much causing high resistance. Had to go back, loosen them all and have them redone to the right torque.

We have Fluke Battery testers, that you can test the cell resistance and internal impedance on a each cell in a 120 cell battery in literally 5 minutes. Hook it up to a PC an you can instatly identify any weak cells.

The ductor tester we have doesn't store the readings that is the next model up from ours. Not too much hassle to be honest.

I use a celltron battery analyser, sounds similar to your fluke. Tests each cell, readings in mhos and tells you whether it is good or not and you can identify deterioration and change out before they fail.

How long is the bus-bars?

Do you have the resistance of the installed bus bars,manufacturer will give their measurements.
Then at least you have a reference point,to check your resistances.
Also if possible voltage test at prone areas.

my double decker bus was 30ft. long and had a bar in it.
