Introduction
2.1 General
The SVERKER900 is an instrument designed for
testing of electrical equipment e.g. protective relay
systems in substations and industrial plants.
SVERKER 900 comes in three models.
Model Test instruments
Basic Main instrument
Prefault-Fault instrument
Standard Main instrument
Prefault-Fault instrument
Ramping instrument
Sequencer instrument
CT magnetization instrument
Expert Main instrument
Prefault-Fault instrument
Ramping instrument
Sequencer instrument
CT magnetization instrument
Impedance instrument
The rugged hardware design is built for field use over
a wide temperature range.
SVERKER 900 is a three-phase test equipment. It can
generate voltage and current from its four voltage
generators and three current generators respectively,
receive binary inputs and a binary output that is a
make/brake contact.
SVERKER 900 can measure external voltages and currents as well, and properties like level, phase, power
factor and frequency of each. The voltage and current
generator outputs can be activated in many combinations. It also includes an external timer with various
start and stop conditions.
All setting for the instrument are made using the
touch screen. The main instrument includes the
"ON+TIME" and "OFF + TIME" functionality.
Another instrument is the prefault fault sequence with
binary input used for trip signals.
The Ramping instrument is used to ramp voltage, current, angle and frequency. One or several parameters
can be ramped at the same time..
The Sequencer instrument has 16 states that can be
individually configured for parameter value, timing
and BI/BO. Equipment for multi task purpose can be
automatically tested here, e.g. different protections
and parameter limit values.
The CT magnetization instrument is used for manual
or automatic "knee point" control on current transformers.
The Impedance instrument is used for testing in so
called impedance plane, where the conversion from
the impedance into voltage and current is done automatically .

3 INSTRUMENT DESCRIPTION
3.3 Binary Inputs
The SVERKER 900 have 4 binary inputs, independent programmable gate circuits that permit simple
selection of the desired mode for voltage or contact
monitoring operation. Binary input 1 has a selectable
threshold voltage.
The binary inputs are used to monitor relay trip contacts for performing pickup and dropout tests as well
as for performing timing functions.
The binary inputs are specifically designed to measure
high speed operation of electromechanical, solid-state
and microprocessor-based protection relays. All binary
inputs are default set to monitor mode, contact /voltage change of state.
To change a binary input state from contact sensing to
voltage applied / removed, touch the "BI" button.
At each binary input there is an input state indicator
lamp that shows the state of the input. It indicates
either a closed circuit (for contact mode) or the presence of a voltage (for voltage mode). These indicators
permit (for example) to check the circuits involved
before starting a sequence.
Dry contacts
Open
Timer stops and a continuity indicator goes out at the opening of
normally closed contacts.
Dry contacts
Close
Timer stops and a continuity indicator glows at the closing of the
normally open contacts.
Application or
removal of AC
or DC voltage
Timer stops. The continuity indicator will glow (application) or darkens (removal) upon the application
or removal of either an AC or DC
voltage. A higher threshold voltage
helps to eliminate false triggers
due to a noisy source. Lower
thresholds allow starting and stopping of timer from TTL voltage
signals.
Binary input 1 has a settable
threshold value for pickup & dropout and minimum settable threshold voltage is 5 V
3.4 Binary Output
The binary output is a make/break contact that is
actuated when the SVERKER 900 is set to ON-generating or OFF-generating mode.
Note In the"Sequence instrument" the make/break
contact position can be set for each state
individually.
The binary output is used to simulate normally
open / normally closed contacts for testing breaker
failure schemes, or similar power system operations. In
addition it may also be used to switch AC/DC voltages
and currents.
For maximum switching capacity see the specification
section.

3 INSTRUMENT DESCRIPTION
3.5 Current generators: I1,
I2, I3
The current generators can be used separately, in parallel or in series. Constant power output in many cases
eliminates the need to connect the current channels in
parallel or series to test high burden relays.
▪
All outputs are isolated or floating and provide variable
frequency.
▪ The current generators delivers maximum compliance
voltage to the load constantly during the test, and range
changing is done automatically, on-the-fly, under load.
The per channel output current and power ratings are
specified in AC rms values. Specified duty cycles are
based upon ambient temperature of 20°C.

3 INSTRUMENT DESCRIPTION
3.6 Voltage generators: U1,
U2, U3 and U4
The voltage generators can be used separately, in
parallel or in series.
▪
All outputs are independent from sudden changes in
mains voltage and frequency, and are regulated so
changes in load impedance do not affect the output.
▪ All outputs are isolated or floating.
▪ All outputs provide variable frequency.
Voltage generator U4 as auxiliary
supply
The primary application for U4 is to provide auxiliary
voltage for protective relays. U4 provides a variable
output from 0 to 300 V AC/DC.
Warning
Do not plug or insert any test lead into
the voltage outputs without first connecting the test leads to the load.
When voltage generators are connected
in series for output over 600 V the special
test leads (brown and purple) must be
used.

instrument only.
3.11 Low current
generation (Optional)
An optional accessory (CR-91010) is the Low Current
Adapter. The adapter consists of two boxes LCA1
and LCA2. It is used to test e.g. sensitive earth fault
protection, capacitor unbalance protection and three
phase reverse power protection.
The LCA1 and LCA2 are to be connected to the current generator outputs, see figure below, for generation of low currents, 0 – 50 mA. The built in ammeter,
in SVERKER 900, is connected to measure the current
injected into the test object.
The ratio between the input and output currents is
somewhat depending on the load, e.g. a 0.5 Ω load
and 1 A current generation gives an output of 9 mA.
Max current input is 5 A.

voltage level
The debounce time for DC voltage can be set from 0
to 999 ms.
For AC voltage the debounce time has to be set to
maximum 5 ms.
Note When set to zero, it actually means 2 – 3 ms. A
debounce time of 0 ms is not a realistic value.
The debounce time means that as soon as a signal
(voltage or contact sense) is detected on the binary
input, SVERKER awaits the set debounce time. If the
signal is active during the whole debounce time the
signal is acknowledged as a valid signal, a “true” trip
signal is confirmed.

Note The BO relay has a switching time at opening
or closing of relay contact that is not compensated for. The switching time is normally
around 3 to 4 ms. When doing a sequence
the BO relay will be switched directly after the
change of sequence state. Meaning that the
switching relay time extends this transition
between the states with this 3 to 4 ms.
4.7 CT magnetization
instrument
In the lid is an accessory placed that is to be used for
the CT magnetization instrument.
The CT magnetization instrument is used to determine
the knee point voltage of a current transformer.
In CT-mode SVERKER 900 can generate up to 900 V
by connecting the four voltage generators in series
and 300 V by connecting the four voltage in parallel.
The magnetization can be made manual or automatic
or as a combination, to start in manual mode and
then switch to auto for the demagnetization part. This
method is good to use for the first test on a CT.

4.10 Calibration
Generally we recommend to calibrate the
SVERKER900 yearly. The parts to calibrate are the
voltage and current generators and the voltage and
ammeter.
Equipment needed:
▪ Digital Multimeter (DMM) with high accuracy. We
recommend the Agilent 34410A or equal.
▪ SVERKER900 calibration box (Art. No. CR-91010).
▪ To make an automatic calibration you will also need
connection via the Ethernet port to a router with DHCP
function or to a switch with network connection.
Calibration procedure
1] In the System Configuration menu, press
In the next menu you can select to do a manual
calibration or an automatic calibration. The automatic
calibration will take about 15 minutes.
Note If you want to save the calibration report to
an USB stick it has to be inserted to SVERKER900 during calibration.
Automatic calibration
The automatic calibration is done by connecting
SVERKER 900 to a DMM (Agilent 34410A or equal)
via a router or a switch. If you use a switch you also
need network connection.
1] To make an automatic calibration the IP ad-
dress for the DMM has to be obtained.
2] Enter the IP number in the “IP Address:”
field.
The TCP port number is by default 5024.
3] Press the button.
4] Connect the router/switch and SVERKER900
according to the picture.
5] Press to confirm.
If the connection between the DMM and the
SVERKER900 succeeded, it is stated in top
Page 43
CR0333LE ZP-CR02E SVERKER900
43
4 OPERATING SVERKER 900
of the menu “Connected to measurement
equipment”.
Now you can proceed with the automatic calibration
of the voltage and current generators and the volt/
ammeter provided the checkboxes are marked for the
specific parts. When a part is calibrated its checkbox
will be greyed out.
6] Press
A connection diagram appears that shows
how to connect for each part.
7] Make the connections.
8] Press
The measurement table menu is shown.
9] Press to start the calibration process.
When the calibration for e.g. U1 is ready it is shown
with a “+” sign for U1 and next calibration will be for
U2.
Manual calibration
In the System Configuration menu, press
1] Press the
2] Select part to calibrate, by pressing desired
part on top of the menu.
3] Press
The connection diagram is shown.
4] Connect the test leads.
5] Press the to continue.
In the picture above, U1 is selected.
6] From the measurement menu press the
to start the calibration of ”U1”.
7] Read out the measured value from the DMM
and use the knob to enter the value.
8] Confirm the entered value by pressing the
knob or the “ >> ” button.
If the values entered before calibration are within
limits, then no calibration will be performed for that
specific range.
For the voltage and current readings only one measurement are taken for each range.
Several readings are taken for the volt/ammeter. Several measurements are taken for each range.
The values entered will be before calibration, values
during calibration and values after calibration. If the
calibration succeeded, there will be a “+” indication beside the U1. If some of the values were out of
limits and the calibration subsequently failed, it will be
marked with a “-“ beside the U1. The specific calibration value that failed is presented on a red background.
The picture below shows the measured values after a
successful calibration of voltage generator 1.
When the calibration has been made the data can be
saved to an USB stick. Using a PC the calibration report can be opened as a Word document or an Excel
sheet.
Calibration report
The front page of the report states the calibration
dates. If the test values during calibration are within
allowed limit, the calibration factors and dates will
remain. The verification dates will be updated.
