Detection of Surges by Frequency Analysis on Lan Equipment

We investigated the frequency characteristics of surges induced on Lan equipments by using V-F converter. which installed on the second part of protection system. We stored and analyzed the frequency converting data with the amplitude of overvoltage. In addition. The data acquisition system was made so that we could be examine the results wave through WEB. From this results, it is found that this frequency analysis could be helped for design and protection of various undesired surges.
