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.
