The discharge of the oil-immersed transformer is more important, the discharge of the oil-immersed transformer is an important activity of the oil-immersed transformer, the key method of its discharge is partial discharge, and the partial discharge of the oil-immersed transformer is relatively harmful to the oil-immersed transformer, and the harm to the human body is there. For the partial discharge of oil-immersed transformers can be inspected, there are many ways to detect the partial discharge of common oil-immersed transformers

The detection methods for partial discharge of oil-immersed transformers generally include:

1. Electrical measurement method. Using an oscilloscope or radio jammer, search for the characteristic wavepattern or radio interference level of the discharge.

2. Ultrasonic measurement. The distance from the detection point to the discharge point can be obtained by examining the sound wave presented in the discharge, converting the sound wave into an electrical signal, recording it on the tape and terminating the analysis, and using the difference between the transmission time of the electrical signal and the acoustic signal.

3. Chemical measurement. Check the content of various dissolved gases in the oil and adjust the change trend. This test can detect changes in the composition, proportion and quantity of the oil, and then determine whether there is a partial discharge (or partial overheating).

The important detection methods and key methods of partial discharge of oil-immersed transformers are the above for you to understand, and you should carry out a good inspection for the partial discharge of oil-immersed transformers, so as to ensure the continuous improvement of the efficiency of oil-immersed transformers.
