Study Notes
Back-to-Back Test
- The back-to-back test is also known as the Sverker Odeen's test.
- Conducting a full-load test for large transformers is difficult due to the requirement of a large load bank, which is often not feasible.
- In the back-to-back test, the primary windings of transformers T1 and T2 are connected in parallel.
- The instruments used in the back-to-back test include two wattmeters, one connected to each transformer, and a switch or a synchronizing device.
- The purpose of the back-to-back test is to measure the losses and performance of a transformer at full load without actually loading it.
