'ENERAL
0REREQUISITE FOR COMMISSIONING IS THE COMPLETION OF
THE PREPARATION PROCEDURES DETAILED IN #HAPTER
(AZARDOUS VOLTAGES ARE PRESENT IN THIS
ELECTRICAL EQUIPMENT DURING OPERATION
.ON OBSERVANCE OF THE SAFETY RULES CAN
RESULT IN SEVERE PERSONAL INJURY OR PROPER
TY DAMAGE
/NLY QUALIFIED PERSONNEL SHALL WORK ON
AND AROUND THIS EQUIPMENT AFTER BECOM
ING THOROUGHLY FAMILIAR WITH ALL WARNINGS
AND SAFETY NOTICES OF THIS MANUAL AS WELL
AS WITH THE APPLICABLE SAFETY REGULATIONS
0ARTICULAR ATTENTION MUST BE DRAWN TO THE
FOLLOWING
!
4HE EARTHING SCREW OF THE DEVICE
MUST BE CONNECTED SOLIDLY TO THE
PROTECTIVE EARTH CONDUCTOR BEFORE
ANY OTHER CONNECTION IS MADE
!
(AZARDOUS VOLTAGES CAN BE PRESENT
ON ALL CIRCUITS AND COMPONENTS CON
NECTED TO THE SUPPLY VOLTAGE OR TO THE
MEASURING AND TEST QUANTITIES
!
(AZARDOUS VOLTAGES CAN BE PRESENT
IN THE DEVICE EVEN AFTER DISCONNEC
TION OF THE SUPPLY VOLTAGE STORAGE
CAPACITORS
!
4HE LIMIT VALUES GIVEN IN THE 4ECHNI
CAL DATA 3ECTION MUST NOT BE EX
CEEDED AT ALL NOT EVEN DURING TESTING
AND COMMISSIONING
7ARNING
7HEN TESTING THE UNIT WITH A SECONDARY INJECTION TEST
SET IT MUST BE ENSURED THAT NO OTHER MEASURED VAL
UES ARE CONNECTED AND THAT THE TRIPPING LEADS TO THE
CIRCUIT BREAKER TRIP COILS HAVE BEEN INTERRUPTED
3ECONDARY CONNECTIONS OF THE CURRENT
TRANSFORMERS MUST BE SHORT CIRCUITED
BEFORE THE CURRENT LEADS TO THE RELAY ARE
INTERRUPTED
)F A TEST SWITCH IS INSTALLED WHICH AUTOMATI
CALLY SHORT CIRCUITS THE CURRENT TRANSFORM
ER SECONDARY LEADS IT IS SUFFICIENT TO SET
THIS SWITCH TO THE 4EST POSITION 4HE
SHORT CIRCUIT SWITCH MUST BE CHECKED BE
FOREHAND REFER TO 3ECTION
$!.'%2
)T IS RECOMMENDED THAT THE ACTUAL SETTINGS FOR THE
RELAY BE USED FOR THE TESTING PROCEDURE )F THESE VAL
UES ARE NOT YET AVAILABLE TEST THE RELAY WITH THE FAC
TORY SETTINGS )N THE FOLLOWING DESCRIPTION OF THE TEST
SEQUENCE THE PRESET SETTINGS ARE ASSUMED UNLESS
OTHERWISE NOTED FOR DIFFERENT SETTING VALUES FORMU
LAE ARE GIVEN WHERE NECESSARY
&OR THE FUNCTIONAL TEST A THREE PHASE SYMMETRICAL
VOLTAGE SOURCE WITH INDIVIDUALLY ADJUSTABLE VOLTAGE
OUTPUTS TOGETHER WITH A THREE PHASE SYMMETRICAL
CURRENT SOURCE WITH INDIVIDUALLY ADJUSTABLE CURRENTS
SHOULD BE AVAILABLE &OR CHECKING THE PICK UP VAL
UES A SINGLE PHASE CURRENT SOURCE IS SUFFICIENT BUT
THIS IS NOT ADEQUATE FOR A CORRECT FUNCTIONAL CHECK OF
THE MEASURED VALUE MONITORING SYSTEMS 4HE PHASE
ROTATION MUST BE CLOCKWISE OTHERWISE TWO PHASES
MUST BE INTERCHANGED IN CURRENT AS WELL AS IN VOLT
AGE !LTERNATIVELY THE BINARY INPUT
NEGATIVE
SEQ
MUST BE ALLOCATED AND ENERGIZED WHICH REVERTS
THE INTERNAL PHASE ROTATION PROCESSING
)F UNSYMMETRICAL CURRENTS AND VOLTAGES OCCUR DURING
THE TESTS IT IS LIKELY THAT THE ASYMMETRY MONITORING WILL
FREQUENTLY OPERATE 4HIS IS OF NO CONCERN BECAUSE
THE CONDITION OF STEADY STATE MEASURED VALUES IS
MONITORED AND UNDER NORMAL OPERATING CONDITIONS
THESE ARE SYMMETRICAL UNDER SHORT CIRCUIT CONDI
TIONS THESE MONITORING SYSTEMS ARE NOT EFFECTIVE
./4%
4HE ACCURACY WHICH CAN BE ACHIEVED DURING
TESTING DEPENDS ON THE ACCURACY OF THE TESTING
EQUIPMENT 4HE ACCURACY VALUES SPECIFIED IN THE
4ECHNICAL DATA CAN ONLY BE REPRODUCED UNDER THE
REFERENCE CONDITIONS SET DOWN IN )%# RESP 6$%
PART AND WITH THE USE OF PRECISION MEASUR
ING INSTRUMENTS 4HE TESTS ARE THEREFORE TO BE LOOKED
UPON PURELY AS FUNCTIONAL TESTS
