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.
