6OLTAGE PROTECTION

-EASURED VALUE FORMATION

4HE VOLTAGE PROTECTION CAN EITHER BE FED BY THE THREE

PHASE TO EARTH VOLTAGES 5

, %

BY THE PHASE TO PHASE VOLTAGES 5

, ,

4HE LATTER CAN BE USED FOR PROCESSING BY THE

VOLTAGE PROTECTION EVEN IF FROM THE SWITCHGEAR ONLY

THE PHASE TO EARTH VOLTAGES ARE AVAILABLE BE

CAUSE THE RELAY IS ABLE TO CALCULATE THE PHASE TO

PHASE VOLTAGES FROM THE PHASE TO EARTH VOLTAGES

4HIS OPTION BETWEEN PHASE TO EARTH AND PHASE

TO PHASE VOLTAGES ALLOWS EITHER TO EVALUATE PHA

SE TO EARTH UNBALANCED VOLTAGES EG CAUSED BY

AN EARTH FAULT OR DISREGARD THEM PHASE TO

PHASE

)T IS ALSO POSSIBLE TO CONNECT TWO PHASE TO EARTH

VOLTAGES AND THE DISPLACEMENT VOLTAGE 5

THE RELAY

THEN CALCULATES THE MISSING VOLTAGE FROM THOSE

WHICH ARE CONNECTED

4HE FUNDAMENTAL WAVES OF THE THREE FED IN VOLTAGES

ARE FILTERED OUT BY A &OURIER ANALYSIS AND THEN PRO

CESSED IN THE FOLLOWING WAY AFTER FORMING THE ABSO

LUTE VALUES THE SMALLEST OF THE THREE VOLTAGES IS AS

SIGNED TO THE UNDERVOLTAGE PROTECTION AND THE HIGH

EST VOLTAGE TO THE OVERVOLTAGE PROTECTION

4HE FREQUENCY ADAPTATION IN THE RELAY IS DESIGNED FOR

THE SYSTEM FREQUENCY q (Z "EYOND THESE LIMITS

THE MEASURING ERROR INCREASES BEARING THE RISK OF

OVERFUNCTION OF THE UNDERVOLTAGE PROTECTION &OR THIS

REASON PICK UP OF THE PROTECTION IS INHIBITED OUTSIDE

THE FREQUENCY ADAPTATION RANGE !N ALREADY EXISTING

PICK UP HOWEVER WILL NOT BE CANCELLED WHEN LEAV

ING THIS RANGE

$EPENDING OF THE SWITCHGEAR DESIGN THE VOLTAGE

TRANSFORMERS CAN BE CONNECTED AT THE INCOMING

BUS BAR OR THE OUTGOING FEEDER SIDE 4HESE DIF

FERENT CONFIGURATIONS RESULT IN A DIFFERENT REACTION BY

THE PROTECTION RELAY TO A FAULT 7HEREAS THE VOLTAGE

PERSISTS ON THE INCOMING SIDE AFTER A TRIP COMMAND

AND OPENING OF THE CIRCUIT BREAKER THE VOLTAGE ON THE

OUTGOING SIDE IS SWITCHED OFF 7HEN THE VOLTAGE IS

SWITCHED OFF PICK UP OF THE UNDERVOLTAGE PROTEC

TION IS MAINTAINED )F RESET OF THE UNDERVOLTAGE PICK

UP IS REQUIRED THEN THE CURRENT CAN BE USED AS AN

ADDITIONAL CRITERION CURRENT CRITERION ## 4HUS THE

UNDERVOLTAGE PICK UP IS MAINTAINED ONLY WHEN TO

GETHER WITH THE UNDERVOLTAGE CONDITION A MINIMUM

CURRENT ADDRESS "2+ #,/3%$ IS EXCEEDED

4HIS CURRENT VALUE CAN BE PARAMETERIZED )F THE CUR

RENT DROPS BELOW THIS THRESHOLD AFTER THE OPENING OF

THE BREAKER THE PICK UP RESETS

5NDERVOLTAGE PROTECTION

4HE UNDERVOLTAGE PROTECTION RECOGNIZES VOLTAGE

DROPS ON TRANSMISSION LINES AND IN ELECTRICAL MA

CHINES AND AVOIDS IMPERMISSIBLE OPERATION CONDI

TIONS AND A POSSIBLE LOSS OF STABILITY

4HE UNDERVOLTAGE PROTECTION HAS TWO STAGES 5

AND 5 SO THAT A TIME GRADED TRIPPING DEPEND

ING OF THE DEGREE OF THE VOLTAGE DROP CAN BE

ACHIEVED 6OLTAGE LIMITS AND TIME DELAYS CAN BE SE

LECTED INDIVIDUALLY FOR BOTH STAGES

4HE 5 STAGE FURTHERMORE OFFERS THE OPTION TO PARA

METERIZE THE RESET RATIO R AND TO SWITCH OVER FROM THE

NORMAL PICK UP THRESHOLD TO AN INDIVIDUAL START UP
