short all the high voltage bushings toghether.do same with low voltage bushings.disconnect the neutral from the ground.earth the body of the transformer.earth the ttr set.
connect the common point of high voltage bushing to hv terminal of ttr and connect the common point of lv bushing to lv terminal of ttr set.connect the neutral of transformet with the n terminal of ttr set.
now crank the generator.im out of time will answer this question later

What are precommissioning tests of transformers?
magnetising current test, magnetising balance test, s.c test, vector group test, winding resistance test, ratio test
Procedure for sumpners test?
Procedure for sumpners test is the single phase transformer. This is a back to back test.
What are the Causes of phase angle error and ratio error at Current Transformers?
RATIO ERROR The secondary current is less than the expected value. The secondary is less in magnitude. This diffence is known as ratio error. PHASE ERROR The angle between the expected and actual secondary current is known as phase error.
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 is magnetic balance test of transformer?
The Magnetic Balance test is conducted on Transformers to identify inter turn faults and magnetic imbalance.
What are precommissioning tests of transformers?
magnetising current test, magnetising balance test, s.c test, vector group test, winding resistance test, ratio test
What allows simple transformers to step up or down?
The voltage ratio in transformers used in power supply is set by the ratio of the number of turns on the primary and secondary windings.
How do you test potential transformers?

Why is the transformer turns ratio test needed?
Turns ratio test is very important in order to find out that the transformer has the right ratio corresponding on its rated voltage in primary and secondary. For example, three phase transformer is subjected to turns ratio test when each phase has equal turns ratio then the transformer is balance.The test is performed to ensure that overheating or overcurrent conditions have not shorted turns in the transformer windings, which would distort the desired output or input voltage. This test is particularly important for instrument transformers, i.e. CTs and PTs which are connected to protective relays. These relays are extremely sensitive, and operate on very small fluctuations in secondary voltage or current. Shorted turns in these transformers can lead to big problems if they cause the relay to operate abnormally, or not at all.

What are two ways of making a stronger voltage using Faraday's law?
Using transformers. The concept of transformers is that it can regulate voltage. Like it can increase the supplied voltage by 10 times or even more. It works in the ratio of coils. This ratio of coils are equal to the ratio of input/output voltages.
300000 current assets 100000 current liabilities and inventory of 150000 what is the acid test ratio?
acid test ratio = quick assets / current liabilitiesacid test ratio = 150000 / 100000acid test ratio = 150 %
What are the Causes of phase angle error and ratio error at Current Transformers?
RATIO ERROR The secondary current is less than the expected value. The secondary is less in magnitude. This diffence is known as ratio error. PHASE ERROR The angle between the expected and actual secondary current is known as phase error.
