AccStopCurr set value. Only for a current lower than set AccStopCurr should activate

the output 

POSOPEN

.

5.4. Check the circuit breaker is in 

INVDPOS

 if auxiliary contacts read same value or CB is

open and inject the current in selected phase more than 

AccStopCurr set value.

6. Test of remaining life of CB

6.1. Test the set timing defined by

RatedOperCurr, RatedFltCurr, OperNoRated,

OperNoFault, DirCoef, CBLifeAlmLevel.

6.2. Vary the phase current in the selected phase from below rated operated current,

RatedOperCurr to above rated fault current, RatedFltCurr of a breaker.

6.3. The remaining life of CB output 

CBLIFEPH

 is estimated when the CB is changed from

closed to open position. Check that the output 

CBLIFEPH

 is decreased with a value

that corresponds to the injected current.

6.4.

CBLIFEAL

 is activated as soon as 

CBLIFEPH

 is below the set 

CBLifeAlmLevel value.

7.

Test of accumulated energy
7.1. Test the actual set values defined by 

AccSelCal to Aux Contact, ContTrCorr and

AlmAccCurrPwr.

7.2. Inject phase current in the selected phase such that its value is greater than set

AccStopCurr value.

7.3. When the breaker goes to open position, accumulated energy 

IPOWPH

 is calculated.

The calculated value can be seen on the output 

IPOWPH

.

7.4. Alarm signal 

IPOWALPH

 appears when 

IPOWPH

 is greater than set 

AlmAccCurrPwr

value.

7.5. Lockout signal 

IPOWLOPH

 appears if 

IPOWPH

 exceeds further to the threshold value

LOAccCurrPwr.

7.6. Calculation of accumulated energy 

IPOWPH

 is stopped when injected current is lower

than set 

AccStopCurr value.

8. Test of CB operation cycles

8.1. Test the actual set values defined by 

OperAlmLevel and OperLOLevel.

8.2. The operation counter, NOOPER is updated for every close-open sequence of the

breaker by changing the position of auxiliary contacts 

POSCLOSE and POSOPEN.

8.3.

OPERALM

 is activated when NOOPER value exceeds the set 

OperAlmLevel value. The

actual value can be read on the output 

NOOPER

.

8.4.

OPERLO 

is activated when NOOPER value exceeds the set 

OperLOLevel value.

9. Test of CB spring charge monitoring

9.1. Test the actual set value defined by 

SpChAlmTime.

9.2. Enable 

SPRCHRST

 input. Also activate SPRCHRD after a time greater than set time

SpChAlmTime.

9.3. At this condition, 

SPCHALM

 is activated.

10. Test of CB gas pressure indication

10.1. Test the actual set value defined by

tDGasPresAlm and tDGasPresLO.

10.2. The output 

GPRESALM

 is activated after a time greater than set time of

tDGasPresAlm value if the input 

PRESALM

 is enabled.

10.3. The output 

GPRESLO

 is activated after a set time of 

tDGasPresLO value if the input

PRESLO

 is enabled.

9.8.3.2 

Completing the test

GUID-0A16206F-690E-46EF-86F4-5A89E0BF640B v3

1.

Continue to test another function or end the test by changing the 

Test mode setting to

Off.

2.

Restore connections and settings to their original values if they were changed for testing

purposes.
