General
The EMP protection unit is sequenced, i.e. to use simultaneously the benefits of inert-gas-filled
surge arresters (extremely high surge capability) and of varistors (fast response). They are isola-
ted by a series inductor.
The arrester is housed in a plug-in socket, so it can be removed and tested without detaching the
lines.
Note on voltage figures:
The maximum voltage on the filter output depends primarily on the rise time until the arrester re-
sponds. For this reason the maximum voltage on the filter output is stated in the following table as
a function of the rising edge dv/dt of the pulse.
