2.2 Design and construction
Thecurrentsource built into SVERKER canprovide
0-10 A, 0-40 A, 0-100 A, 0-250 V ACor
0-300 V DC.Timingandgeneration(output)can be
carriedoutsimultaneously. When therelayprotection
equipment trips, bothoutputandtiming are inter-
rupted.
Note The current output depends on the burden of
the relay (circuit). This means that it is possible
to get high output currents, over the maxi-
mum measurement range of 250 A.
There is also a separate built-in AC voltagesource to
supplytherelayvoltageinput.
A20-220 V DC voltagesource is used to provide
auxiliary voltage.
Thequality of theoutputsignal is depending onthe
quality of theinputvoltage. If themainvoltage is
distorted theoutputsignalwillalso be distorted.
However, the AC voltagesource inSVERKER 780 is
fully synthesizedbytheinstrumentsitselfandthere-
foreindependent of themainsinputvoltage.
SVERKERis equippedwith a timer,ammeterand
voltmeter, andtheseinstrumentscanalso be used to
indicateresistance,impedance, phase angle,power
andpowerfactor.Moreover,theseinstrumentscan be
usedformeasurements in externalcircuits.
Aset of resistorsand a capacitor (SVERKER 750) are
provided, andtheycan be connectedintothecircuits
beingtested to provide phase shifts,fineadjustments
andthelike.
Amake/breakcontactcan be used to synchronize
othercircuitswithteststhatarebeingconducted.
SVERKER settingsare made usingknobsandother
controlsonthecontrolpanel.Numerousotherset-
tings can be made viathedisplaywindow built into
thecontrolpanel.

3DESCRIPTION
3.3 Timer
Since the timer has a startinputand a stop input,
it can be used to measureexternal cycles as well as
sequences initiated bySVERKER. The measuredtime
appears in the displaywindow.
Totestautomaticreclosingdevices, SVERKERis able
to measure a number of sequentialtimeintervals and
displaytheresultslater.
Theinputs can be set individually to respondeither to
zero-potential contactoperation ortoa voltage (AC
or DC).
Input state indicators
At each timer START and STOP inputthere isan input
stateindicatorlampthatindicates the state of the
input. When the indicatorlamp is lighted, it indicates
either a closedcircuit(forcontactmode) or the pres-
ence ofa voltage(forvoltagemode). These indicators
permit you to (forexample)check the circuitsinvolved
beforestarting a testsequence.
Start conditions
Thetimer can be started in the followingways:
Indication Start condition
INT a) When an internalstartoccurs, i.e. for a test
sequence started bySVERKER (ON+TIME or
OFF+TIME).
b) When a voltage is applied to the startinput
orwhen a contact is closed.
c) When a voltageapplied to the startinput
vanishes or when a contact is opened
d) When the state of the inputchanges.
Stop conditions
Thetimer can be stopped in the followingways:
Indication Stop condition
INT a) When an outgoingcurrent is interrupted
(internaldetection).
b) When a voltage is applied to thestopinput
orwhen a contact is closed.
c) When a voltageapplied tothe stopinput
vanishes or when a contact is opened.
d) When the state of the inputchanges.
Measuring an external cycle
Before measuring, SVERKER must be set tothe
ON+TIME state,whereupon the timerwillalso be
cleared to zero.
Clearing the timer
Thetimerwill be cleared to zerowhengeneration
startsagain.
Testing automatic reclosing devices
Asettingmust be made viathe displaywindowbefore
you can testautomaticreclosingdevices. ON+TIME is
lighted throughout the entirecycle.Generationstarts
again each time the timer'sstartinput is activated.

3.4 Trip indicator
When the stopcondition is met, theTRIP indicator is
lighted. Thislampindicates tripping of the relay pro-
tection equipment. When a testincludes timing, this
indicator lampflasheswhen tripping occurs.
3DESCRIPTION
3.5 Display
Current, voltage and otherentities can be shown on
thedisplay.
Thedisplaywindow is alsoused to makesettings. To
do this, you must put SVERKERin the settingmode by
pressing the buttonmarked MODE.

3DESCRIPTION
3.6 Ammeter & voltmeter
SVERKER is equippedwith an ammeter and voltmeter.
These instruments can also be used to displayresist-
ance,impedance,phaseangle,power and power
factor. Moreover,theseinstruments can be used to
perform measurements in externalcircuits. In both
cases, the valuesappear onthe display.
Theammetermeasures one of the following:
•Current at one of thecurrentoutputs0-100 A,
0-40 A or 0-10 A.
•Current inan externalcircuitconnected to the
SVERKER 750/760ammeterpanelinput(marked
®).
Youselect the desiredmeasurementsite(testpoint)
using the buttonmarked A, whereupon a indicator
lamplights at the selectedmeasurementsite.
Thevoltmetershows the voltageconnected to the
voltmeter input(marked V)on the panel.Thisinput is
always activated.
Theammeter and voltmeterbothchangerangesauto-
matically, butthey can also be changedmanually. For
AC,theymeasuretrue RMS value. Youcan change
from ACtoDC and viceversa.
Note When using AUTO RANGE the measured
value can be totally wrong. This can happen
when a previous value was in another range
than the present value.
Set the correct range (see section 9.5) and/or
repeat the same test again.
A HOLD (freeze)functionpermits you to measurevolt-
ages and currentshavingduration as short asa quar-
ter of themainscycle. When the timer is stopped, the
current and voltagevalues are frozen. If thetimer is
not stopped, the valuespresentwhen the current was
interrupted are frozen. The holdfunction is engaged
bypressing the buttonmarked HOLD. can some-
timesappearduringmeasurement of high-speed AC
cycles when the holdfunction is invoked.Thismeans
that no valuecould be presented because the cycle
wastooshort.
If O.F. (meansoverflow, i.e.a valuebeyond the meas-
urementrange)appears, the cyclebeingmeasured
may have been so fastthattherewasn'ttimefor
automaticrangechanging. In such case, you should
repeat the measurement. The range-changingsystem
ismemory-equipped, and repeatingyourmeasure-
ment may give it time to make the changeproperly.
When currentand/orvoltagefluctuatewidely, a filter
can be engaged to makereadingeasier. The filter
performs an averaging function.
Instead of havingcurrent and voltageshown in
amperes and volts, youcan have themshown asa
percentage ofa givencurrent or voltage (the relay
protection equipment'ssetting for example). A flash-
ing currentvaluemeansthat the value is less than 1 %
of therangebeingused. To get a moreaccuratecur-
rent reading, youcan thenmeasure viathe ammeter
input.

3DESCRIPTION
3.7 AC Voltage source
SVERKER 750
The AC voltagesourceprovides0-120 V AC (split
into two ranges). It hastwo knobs of itsown, onefor
rough andonefor finesettings. Since the AC voltage
source is separatedfromotheroutputs, itisset inde-
pendently of the currentsource.
The AC voltagesource is intendedprimarilyfor the
relayprotectionequipment'svoltageinput. A set of
resistors and a capacitor can be used to change the
phase angle of the current andthe voltage.
SVERKER 780
The AC voltagesourceprovides5-220 V AC with
adjustablephase-angle and frequency. Since the AC
voltagesource is separatedfromotheroutputs, itis
setindependently of the currentsource.
Thegeneratedwaveform is independentfrom the
mains AC supply asitis internallysynthesized by the
SVERKER 780.
The AC voltagesource is intendedprimarilyfor the
relayprotectionequipment'svoltageinput.
Note For correct RMS readings the Ammeter/
Voltmeter is automatically set to the mains
frequency at start up.
When theAC voltage source is switched on
and "Frequency" has been selected as anad-
ditional measurement parameter the sampling
interval of the Ammeter/Voltmeter is automat-
ically set to measure correctly at the selected
frequency of theAC voltage source.
In order to supply an accurate measurement
for other frequencies than 50/60 Hzit is nec-
essary to do the following adjustment.
1] Turn on the independent AC voltageoutput.
2] Enter the measurementmenu and select
Frequency (U).
3] Exit the menu.
4] Adjust to the desiredfrequency.
Note As long as theAC voltage output is turned
on the selected frequency is used for voltage
and current measurement. If turned off the
measurement returns to 50/60 Hz.
3.8 Auxiliary voltage source
Theauxiliaryvoltagesourceprovides20-220 V DC
(split into two ranges). Itis equippedwithovercurrent
protection, and itis separate from the otheroutputs.
Moreover, it can be used to supply the relaybeing
tested.

3DESCRIPTION
3.9 Make/Break contact
There isa make/breakcontactthat is actuatedwhen
SVERKER is set to the ON+TIME or OFF+TIME state.
It can be used, for example, to synchronizeother
equipment or to change the voltagesupplied to the
relayprotectionequipment at the start ofa testfrom
non-faulty to faulty or vice versa.
3.10 Resistor setand capacitor
Theresistor setand capacitor can be used to change
the phase angle of the current and voltage.
Note There isno capacitor on the SVERKER 780.
The phase-angle is set with the knob atthe
AC voltage source.
