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.

3.10 Ethernet port
Note The Ethernet port is used for service of the
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.
