I am surprised to see your answer. If you don't know what the 'Ductor Test' is, you should not answer simply by searching internet and find something else that is completely different from what you are answering. I am pretty sure you don't know what is 'Ductor Test' is – otherwise you wouldn't indicate 'Duct Test' as 'Ductor Test'. The 'Ductor Test' is used to determine contact resistance in micro-ohm range for the high current carrying devices such as beaker contacts, bus bar connections etc.
I have only done this once, but the basic procedure was fairly simple.
A ductor has four leads: The two (Positive and negative) high amperage DC leads, and two smaller (Also positive and negative) leads. the actual name of these leads i do not know, but I know they are used to negate the resistance of the high amperage leads from the reading (to provide a more accurate reading).
It is very important that the polarity is maintained between the two sets of leads. Also it is very important that the smaller set of leads are connected on the correct "Side" of the high amperage leads. By side I mean electrically speaking. You want the smaller leads to parallel the high amperage leads so that the resistance of the leads and their connection to the busbar can be measured and negated from the reading. If they are connected on the wrong side of the high amperage leads, the smaller leads essentialy wont be part of the cicuit and the resistancer of the leads and connection will be included in the final reading (False reading of high resistance). Also you want the two sets of leads to be as close together as possible without them touching.
After that, test the bus, record the reading, and repeat for each bus. I can't remember if you're supposed to maintain the test for any period of time, like a meggar or hi-pot.
The person who wrote it certainly could. Does the facility not have a copy, then?
