SUMMARY
The metal component on top of testing transformers is identified as a Corona Ring, commonly made from hollow aluminum. Its primary function is to mitigate corona discharge, which becomes significant at high voltages starting around 1000V and intensifying beyond 100kV. The rounded shape of the ring reduces the voltage gradient at sharp corners, thereby preventing air ionization. This design contrasts with that of a lightning rod, which serves an opposite purpose.
