WebApr 3, 2024 · The basics of radar is that a beam of energy, called radio waves, is emitted from an antenna. As the waves strike objects in the atmosphere, the energy is scattered in all directions, with some of the energy reflected directly back to the radar. The larger the object, the greater the amount of energy that is returned to the radar. WebRated frequency: The standard rated frequencies of lightning arresters are 50Hz and 60Hz. Rated nominal discharge current: This is the discharge current that an arrester picks during discharge of surge current. ...
