EDR-3000 IM02602003E
Commissioning: Switch Onto Fault [ANSI 50HS]
Object to be tested:
Testing the module Switch Onto Fault according to the configured operating mode
:
I< (No current);
Bkr state (Breaker position);
I< (No current) and Bkr state (Breaker position); and
Bkr manual CLOSE.
Necessary means:
Three-phase current source (if the Enable Mode depends on current);
Ampere meters (may be needed if the Enable Mode depends on current); and
Timer.
Test Example for Mode Bkr Manual CLOSE
Mode I< (In order to test the effectiveness): Initially, do not feed any current.
Start the timer and feed with an abruptly changing current that is distinctly
greater than the I<-threshold to the measuring inputs of the relay.
Mode I< and Bkr state: Simultaneously, manually switch on the breaker
and feed with an abrupt change current that is distinctly greater than the
I<-threshold.
Mode Bkr state: The breaker has to be in the OFF position. The signal
„SOTF.
ENABLED
“=0 is false. If the breaker is switched on, the signal
„SOTF
.
ENABLED
“=1 becomes true as long as the timer t-effective is running.
The breaker has to be in the OPEN position. There must be no load current.
The status display of the device shows the signal "SOTF.
ENABLED
“=1.
Testing:
Manually switch the breaker to the CLOSE position and start the timer at the same time.
After the hold time t-enable is expired, the state of the signal has to change to "SOTF.enabled“=0.
Write down the measured time.
