Abstract:

According to a disconnector circuit resistance test, electromagnetic environment of the test site is analyzed. By calculating the electromagnetic field in the test environment and the induced voltage in the test circuit, the electromagnetic interference has been proved to be an important reason for the distortion of the disconnector circuit resistance. By improving the wiring method of disconnector measuring circuit, the influence of electromagnetic interference on measuring the resistance of the disconnector is reduced. The measured value of disconnector circuit resistance is more accurate and reliable, which improves the accuracy while testing disconnector circuit resistance and the production efficiency during grid maintenance.
