Abstract

Sustav za lociranje struje munje nam daje podatke o mjestu udara, amplitudi struje munje i njezinu polaritetu te točnom vremenu udara. Na osnovu tih podataka se odabire prikladan odvodnik prenapona na vodu. Kako bi se kalibrirali sustavi za lociranje udara munje, provodi se mjerenje struje munje na nekom visokom tornju koji je izložen čestim udarima munja.

U ovom radu su prikazani sustavi za mjerenje struje munje temeljeni na magnetizaciji te sustav za mjerenje struje munje u realnom vremenu... More instaliran na telekomunikacijskom tornju. Less

Abstract (english)

Atmospheric discharges are the main cause of line failures. In the selection of the suitable surge arrester, it is useful to know lighting stroke distribution in a certain area.

Lightning location system gives us information about lightning parameters such as amplitude, polarity and where and when stroke happened. In order to calibrate this system, we are measuring real lightning current shapes. Lightning current measurement system is implement on high telecommunications tower which is... More often exposed to the lightning strokes.
