Why test transformer turn ratio?

Before new power transformer working, we have to checking if the winding number and turn ratio is right, checking the situation of tap switch, checking if there is short-circuit in winding, the testing result will supply data reference before new power transformer sent to power grid.

The allowable deviation for below 35kv should be±1%, rest of all transformer should be under±0.5%.

KRI supply JYT-F and JYT-A Turn ratio tester which has stable capability and precise testing result will help you find reliable testing reference for all type of transformer.
