The most common and destructive ESDs are primary and secondary lightning
strikes. Primary lightning strikes hit instrumentation directly. Secondary strikes
induce voltage in power lines or wires connected to instrumentation. While
elaborate, expensive, and nearly infallible lightning protection systems are on the
market, Campbell Scientific, for many years, has employed a simple and
inexpensive design that protects most systems in most circumstances. The
system employs a lightening rod, metal mast, heavy-gage ground wire, and
ground rod to direct damaging current away from the CR3000. This system,
however, not infallible. Figure Lightning Protection Scheme
(p. 109)
is a drawing
of a typical application of the system.
