Ar ko var nodrošināties, lai zibens neizsper kompi?
Vai šitie surge "pagarinātāji" ar' ir kautkam noderīgi,



vai uzreiz jāskatās uz UPS kastēm? Un tad cik nopietnām kastēm?

UPD. Paldies par padomiem un atbildēm!
Kā sapratu drošas aizsardzības nav, tad laikam jāpaņem vismaz surge pagarinātājs pret strāvas svārstībām.

2.3 Indirect effects due to Lightning Electromagnetic Pulse (LEMP)
Lightning stroke, particularly the return stroke part of the lightning, forms a
high current electric discharge in air. The current peak magnitudes are of the
orders of several tens of kilo amperes. This current is in the form of a pulse.
Due to its rapidly time-varying characteristics (large time rate of change of
current), it sets up time varying electromagnetic (EM) fields. These time
varying EM fields induce voltage and current surges in electric circuits in the
region illumined by Lightning Electromagnetic Pulse (LEMP). Solid-state
electronic components and circuits are particularly vulnerable to these lightning
induced voltages and current surges....
