During commissioning energization sequences should be carried out, to check the sta-
bility of the protection also during closing operations. Oscillographic event recordings
contain the maximum information about the behaviour of the protection.
Along with the capability of storing fault recordings via pickup of the protection func-
tion, the 7SJ62/63/64 also has the capability of capturing the same data when com-
mands are given to the device via the service program DIGSI, the serial interface, or
a binary input. For the latter, event „>Trig.Wave.Cap." must be allocated to a
binary input. Triggering for the oscillographic recording then occurs, for instance, via
the binary input when the protection object is energized.
An oscillographic recording that is externally triggered (that is, without a protective
element pickup or device trip) is processed by the device as a normal oscillographic
recording, and has a number for establishing a sequence. However, these recordings
are not displayed in the fault log buffer in the display, as they are not network fault
events.
The procedure is described in detail in Chapter "Mounting and Commissioning".
