Analysis of Efficiency and Characteristics of a Frequency-Dependent Device Based on Nanocrystalline Ferromagnetic Material
The article considers the issue of protecting substation equipment and overhead lines from high-frequency lightning surges using a device based on a nanocrystalline tape made of an amorphizing ferromagnetic alloy. The object of protection is a substation that uses a cable insert between the overhead line and the substation input. A distinctive feature is the fact that the 35-kV overhead line is made on pores for 110-kV overhead lines. A high danger of surges is shown with such a configuration of the overhead line that includes a cable insert. A method for protecting against high-frequency surges is proposed using a frequency-dependent device operating on the use of an anomalous skin effect.
