Abstract :
The selection of measuring points is an important problem for the vibration monitoring of transformers. The paper analyses the corresponding selecting principles. A series of experiments were conducted in one 220kV transformer with fixed-frequency variable current. The experimental results showed that the measuring points should be placed on the base of windings and the side wall of the tank. Another experiment was conducted with variable-frequency fixed-current. The results showed that different exciting frequency was important for choosing measuring points. Finally, three selecting principles were summarized.
