Its a test conducted on two identical 1- phase Transformers to determine the efficiency at different loads (without actually connecting any load).

Procedure for sumpners test?
Procedure for sumpners test is the single phase transformer. This is a back to back test.
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 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..
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
Why sumpners test is also called regenerative test?
Sumpner's test is also known as the regenerative test because it evaluates the performance of a transformer under conditions that allow energy to be returned to the power source. In this test, both the primary and secondary windings of the transformer are connected to the same alternating current source, enabling the transformer to operate at no-load and load simultaneously. This setup helps assess the transformer's efficiency and losses, providing insights into its regenerative capabilities. As a result, the test highlights how the transformer can regenerate energy rather than just dissipate it as heat.
