10.4.7.4

Verifying the back-up trip mode

SEMOD128582-115 v2

In the cases below it is assumed that

FunctionMode

Current

is selected.

Checking that back-up tripping is not achieved at normal CB tripping

SEMOD128582-119 v4

Use the actual tripping modes. The case below applies to re-trip with current check.

Procedure

Apply the fault condition, including START of CCSRBRF, with phase current
well above set value

IP>

Arrange switching the current off, with a margin before back-up trip time,

It may be made at issue of re-trip command.

Check that re-trip is achieved, if selected, but no back-up trip.

Disconnect AC and start input signals.

10.4.7.5

Verifying instantaneous back-up trip at “CB faulty” condition

SEMOD128582-167 v4

Applies in a case where signal “CB faulty and unable to trip” is connected to input
CBFLT.

Procedure

Repeat the check of back-up trip time. Disconnect current and START input
signals.

Activate the input CBFLT. The output CBALARM (CB faulty alarm) should
appear after set time

tCBAlarm

. Keep the input activated.

Apply the fault condition, including START of CCSRBRF, with current
above set current value.

Verify that back-up trip is obtained without intentional delay, for example,
within 20ms from application of START.

Disconnect injected AC and input signals.

10.4.7.6

Verifying the case

FunctionMode = Contact

SEMOD128582-183 v4

It is assumed that re-trip without current check is selected,

RetripMode

CBPos Check

Procedure

Set

FunctionMode

Contact

Apply input signal for CB closed to relevant input or inputs CBCLD

Apply input signal, or signals for START of CCSRBRF. The value of current
could be low.

Verify that re-trip and back-up trip are achieved after set times.

Disconnect the START signal(s). Keep the CB closed signal(s).
