Research on lightning current detection of high voltage overhead transmission lines

Aiming at the problem that the detection effect of lightning current of transmission line is not good, a new detection method of lightning current of high voltage overhead transmission line is proposed. Firstly, the lightning phase jitter value of the overhead transmission line is collected and calculated, then the lightning area is located according to the jitter frequency, the lightning area value is collected, and the harmonic detection protocol stack is set according to the calculation results to ensure the lightning current detection effect of the overhead transmission line. The experimental results show that this method is superior to the traditional method in detecting lightning current of high voltage overhead transmission lines, and fully meets the research requirements.
