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.

What is the meaning of magnetic balance test?
Magnetic balance test is performed on transformer to check, whether the core and windings of the transformer is balance position or not. Magnetic Balance is a test of Critical use as it helps us to enhance the efficiency and life of transformers.
Why the open and short ckt test of transformer is needed?
The open/short-circuit test on a transformer isn't 'needed'. It's only used if you want to find out the efficiency of a transformer.
Can you use ordinary transformer in place of auto transformer?
yes we can place auto transformer in place of original transformer
What is the use of ideal transformer?
Ideal transformer is useful in understanding the practical transformer..i does't have losses...
Can a high voltage transformer be megged with a megger meter?
No. A megger's output voltage is not high enough to test the insulation of a high-voltage transformer if, by 'high-voltage transformer ', you mean a distribution transformer or power transformer. Instead, a high-voltage test set or 'pressure tester' (e.g. a 'HiPot' tester) must be used, as these produce far higher voltages.
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 .
What is Back to back test of a transformer?
Back to back testing of a transformer can be better explained if you check the diagram in the resource area.
Procedure for sumpners test?
Procedure for sumpners test is the single phase transformer. This is a back to back test.
What is dielectric test in transformer?
why need dielectric test for transformer
How will be conduct test on transformer?
Short circuit test and open circuit test are widely used to test the efficiency of the transformer.
What are the purposes of performing no load test for the transformer?
These two tests are performed on a transformer to determine (i) equivalent circuit of transformer(ii)voltage regulation of transformer(iii) efficiency of transformer. The power required for theseOpen Circuit test and Short Circuit test on transformeris equal to the power loss occurring in the transformer.
What is the meaning of magnetic balance test?
Magnetic balance test is performed on transformer to check, whether the core and windings of the transformer is balance position or not. Magnetic Balance is a test of Critical use as it helps us to enhance the efficiency and life of transformers.
Did Megatron come back in transformer 2?
Yes they use the shard to bring him back to life
Why the open and short ckt test of transformer is needed?
The open/short-circuit test on a transformer isn't 'needed'. It's only used if you want to find out the efficiency of a transformer.
Why the polarity of transformer is important?
a polarity test is a test which use to check the polarity of tranformer.the rision of this test to running the two or more transformer in parallel.like bettry situation or to fin the terminals
What is the purpose of conducting sc and oc test of single phase transformer?
to determine the transformer characteristics...
