it is so called as there are two identical Transformers which are connected together such that there secondaries are in series opposition

Why should you use sumpners test on transformer?
sumpners test is performed to find core losses and copper losses.here we can find effieciency and regulation by actually simulating the loading conditions.hence the results obtained by this method are more accurate than oc and sc test where loading conditions are absent.we can perform heat run test which is an advantage of sumpners test as both losses occur simultaneously
Why are oc and sc tests preferred when compared to sumpners test?
OC and SC tests are used for predetermining the efficiency and % voltage regulation. It is more efficient test for a transformer than sumpner's test for 2 reasons. 1. two identical transformers are readily not available 2. two separate power supplies are required for the sumpner's test, whereas OC and SC are simple and best
What is the use of back to back test in transformer?
Back to back test give data for finding the regulation , efficiency and heating under load condition. Back to back test is performed in the presence of two identical transformer. In this test one transformer remains open and other remains loaded. Hence sumpner's back to back test is generalised form of o/c test and s/c test which is performed within one test only. Hence from this test we find core loss and full load copper loss simultaneously at a time.
Why is the DO loop called a pre-test loop?
No reason. It is a post-test loop.
What motor test will determine if someone is drunk?
It's called a 'sobriety test'
Procedure for sumpners test?
Procedure for sumpners test is the single phase transformer. This is a back to back test.

Why sumpners test is called heatrun test?
The temperature rise is not considered in OC & SC tests of transformers.. But in Sumpner's test, temp. rise is considered.. Hence is called "Heat-run test".. Also, the transformers draw only the power req. to supply core & Cu. losses of transformer..
What do you mean by sumpners test?
Its a test conducted on two identical 1- phase transformers to determine the efficiency at different loads (without actually connecting any load).
What is the use of sumpner's test in transformer?
this test helps in finding the core losses and copper losses in single test , it is also called as back to back test or heat run test .

How do you find out what type of dog is right for you?
you can either by a book called the dog selector and take the test at the back or go on a website and take a test!
What happens in army if urine test come back diluted?
if test comes back in any way compromised, it is a sure bet that the person in question will be called on it and could be charged for whatever reason.
What is the taks test now call?
It is called the star test. It will not be called the taks test anymore, but it will be called the star test.

Is it true that there is a blood test that can tell you the gender of a baby while being pregnant?
yes there is but its not accurate and they are NOT willing to provide money back! but there is a urine test called intelligender which some say it works.. and its about $40... whereas the blood test is $500...
What are test tubes called?
A group of test tubes are called samples.
