Failure Simulator (Sequencer)*
Available Elements:
Sgen
* = Availability depends on ordered device. This applies especially to the availability of voltage and current. Voltage simulation is only available in
voltage relays, current simulation is only available in current relays.
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 (Prot inhibit)/WARNING!
Cont?/Sine wave gen] menu. The simulation cycle consists of three states:
Pre-failure;
Failure; and
Post-failure State (Phase).
Within the [Service/Test Mode (Prot inhibit)/WARNING! Cont?/Sine wave gen/Configuration] 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 exceeds 0.1 times In. A simulation can be restarted, five seconds after the current has fallen below 0.1 times
In.
Setting the device into the simulation mode means taking the protective device out of
operation for the duration of the simulation. Do not use this feature during operation of
the device if the User cannot guarantee that there is a running and properly working
backup protection.
The energy counters will be stopped while the failure simulator is running.
