Additionally you can define a ramp for each phase via amplitude, phase or frequency via the ramp functions.
You can still define 3 various harmonic superimpositions per phase. This allows the setting of ramps within
one test step. If additional binary inputs are effective, you can adjust that in the section below. Using a hook
tag which binary input is active during the test step. If a voltage (corresponds logically to 1) is present, the
binary input is active.

You can a use created test sequence, for example, for a protection function test. Start a test sequence in the
protection function test editor in DIGSI 5. You can also start a test sequence through a binary input of the
device. By starting through a binary input you can play back test sequences in several devices simultaneously.
You lay down the start criterion for the device using DIGSI 5
values directly into the functions of the device by bypassing the analog and binary inputs. Before starting a
sequence DIGSI 5 switches the device to a simulation mode that activates the internal signal generator.
To check a protection function systematically, click again in the project tree the Test button and open the
Protection function test menu item. You are offered the existing protection functions and you can select
which protection function is tested. The characteristic curve of the protection function appears in the oper-
ating range (see
of spontaneous indications is updated simultaneously. Feeding through a test sequence is done in this simula-
tion mode where the protection functions work with the calculated sampled values of the sequence.
Switching to an internal sequence is done in DIGSI 5. The designated sequence is selected (it must first have
been configured offline), loaded into the device and its progress activated.
A SIPROTEC 5 device has numerous protection and supervision functions that work in parallel. For the tests
switch some or only the function to be tested. For this purpose, a test aid that greatly simplifies the test for
you was set up in SIPROTEC 5.
The protection functions have indirectly the same setting as when you switch the mode to Test in the func-
tion. In this state, the protection function is active. In addition, a test bit is generated and transmitted with
every indication. In the Test setting the routed relay in the device is not activated and the circuit breaker is
thereby not actuated.
Upon exiting of the test mode, the execution of an authorized test period or the conscious switching to the
normal operating state (Process mode) leads to the deactivation of the temporary settings. The original
setting then becomes active. You can also make us of this test menu to have a quick overview of available and
enabled protection functions.
