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

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.
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.
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...
What is use of metering core in transformer bushing?
It is the current transformer core meant for metering.
What is the application of pluse transformer?
why should we use pulse transformer rather than ordinary transformer
Can you use transformer with your 110 aircon?
A transformer can be used to change the voltage to an appliance. The voltage rating of the transformer should be right for the voltages used, and the current rating of the transformer should not be less than the current drawn by the equipment.

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 .

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
Which type of transformer is use in gss?
Frgi transformer
Can you use ordinary transformer in place of auto transformer?
yes we can place auto transformer in place of original transformer
Can you use a 30 amp disconnect switch for a 30 kva transformer?
im have a 30 kva transformer 3 phase 480v 80 amp panel 120v what size disconnect should I use
What is the use of ideal transformer?

Why you use upf wattmeter for short circuit test on load test on single phase transformer?
If, by 'upf', you mean 'unity power factor', then allwattmeters measure the in-phase component of the load current, so the term is quiet unnecessary.A short-circuit test is used to determine the (true) power loss in the transformer, which is exactly what a wattmeter measures
What size cable to use for an AC transformer so that it runs twenty four hours a day?
The Transformer rating should be well above the total running load of the house
