Test event reporting to SCADA system with Force stage function
IMPORTANT
NOTE: Forcing protection stages might also open the
circuit breaker if the protection function has been configured to do so from
Trip-event. Safe settings-mode prevents this which is explained at the end of
this document.
Testing event broadcasting to
SCADA system can in some cases be time consuming or not an option if a relay testing device is not available. To test if the SCADA system receives the events from the relays without
using relay testing devices like Omicron, using Stage
Forcing can come in handy.
To start out enable Live Edit-mode and enable stage forcing in General
menu. Now the states of the protection functions (Normal, Started, Trip,
Blocked etc.) can be activated by the parameter setting in each of the protection
functions page (see image below).
If the breaker is closed and opening it is not desired using Safe settings mode prevents that from
happening. When Safe settings mode is in use the protection relay works otherwise normally but none of the output relays can change state. This mode can be enabled/disabled from Commands > Toggle safe settings mode. When safe settings mode is
enabled the active mode is displayed with a skull in the mimic displays top
right corner, SAFE MODE text next to Live
Edit-text and ERROR-LED.
The safe settings mode can be reversed back to normal by repeating Toggle safe settings mode. To reset
ERROR-LED go to Monitoring à Device Diagnostics and clear the
Internal relay fault message with Clear
Fault status.
