* = Availability depends on ordered device.
For commissioning support and in order to analyze failures, the protective device offers the option to simulate
measuring quantities. The simulation menu can be found within the [Service/Test Mode/Sgen] menu.
The simulation cycle consists of three states:
1. Pre-fault;
2. Failure;
3. Post-fault State (Phase).
In addition to these three states, there is a short “reset stage” of about 100 ms immediately before the Pre-failure
state, and another one after the Post-failure state, where all protection functions are deactivated. This is necessary
to re-initialize all protection modules and related filters and set them to a healthy new state.
The states are recorded by the Event and Disturbance Recorders as follows:
•
0
Normal operation (i. e. without fault simulation)
•
1
Pre-fault
•
2
Fault
•
3
Post-fault
•
4
Reset / initialization phase
Within the [Service/Test Mode (Prot inhibit) / Sgen / Configuration / Times] sub-menu, the duration of each phase
can be set. In addition; the measuring quantities to be simulated can be determined (e. g.: voltages, currents, and
the corresponding angles) for each phase (and ground). The simulation will be terminated, if a phase current
