Abstract:
A study of the performance of wideband magnetic direction finding systems used in
locating lightning ground flashes in Sri Lanka is presented. The studies carried out with
these systems show that they are highly sensitive to the geometric placement with
respect to each other as well as to the induced magnetic fields produce by the external
objects in the vicinity of the antennas (site errors). The results of two studies carried out
by placing two of these stations in the same vicinity of each other and also in two
remote locations (Colombo 6.90° N, 79.86° E and Ratnapura 6.68° N, 80.40° E) are
presented.
