The exact wave that is delivered isdetermined by the instantaneo

Usually, this surface is themetallic hull of the ship. On a nonmetallic hull ship, a specialground system is installed for this purpose.3.7 follow (
11、power) currentThe current from the connectedpower source that flows through a surge protective devicefollowing the passage of discharge current.3.8 frequency toleranceFrequency tolerance is the maxi-mum permitted departure from nominal frequency duringnormal operation, excluding transient and cyclic
12、 frequencyvariations. This includes variations such as those caused byload changes, switchboard frequency meter error, and drift.Unless specified otherwise, frequency tolerance shall be con-sidered to be 610 % of nominal frequency.3.9 inrush currentThe inrush current is a sudden changein line curren
13、t that occurs during startup or as a result of achange to the operating mode. Inrush current is dependent onthe type of load connected to the surge suppressor, andtypically will rise to a maximum value in a few millisecondsand decay to rated value in several milliseconds to severalseconds.1This spec
