Abstract (en)
[origin: EP0521805A1] It comprises two opposed electrodes (1, 2) united, on the one hand, in series by a low-voltage varistor (3) through which pass possible lightning waves and, on the other hand, in parallel via a resistor (7) which does not react during a lightning wave but rises in temperature during passing of the current generated by the grid in order to at least partly destroy a sleeve (11) surrounding the indicator. <IMAGE>
