Description
The SVERKER 750 Relay Test Set is the engineer's toolbox.
The control panel features a logical layout, still SVERKER 650
users will find it comfortably familiar and will be able to start work
right away.
The SVERKER 750features many functions that make relay
testing more efficient. For example, its powerful measurement
section can display (in addition to time, voltage and current) Z, R,
X, S, P, Q, phase angle and cos φ. The voltmeter can also be used
as a 2nd ammeter (when testing differential relays for example). All
values are presented on a single easy-to-read display.
You can also test directional protective equipment efficiantly by
means of the built-in variable voltage source. In SVERKER 780
this has a continuous phase shift function and adjustable frequency
as well. Automatic reclosing devices can also be tested – just as
easily.
Designed to comply with EU standards and other personal and
operational safety standards, SVERKER 750/780 is also equipped
with a serial port for communication with personal computers and
the PC software SVERKER Win. Since the compact SVERKER
weighs only 18 kg (39 lbs), it’s easy to move from site to site.
Two or more SVERKER units can also be synchronized, which
for example allows the user to connect three SVERKER into a
basic 3-phase test set.

Other fields of application
▪▪Plotting excitation curves
▪▪Current and voltage transformer ratio tests
▪▪Burden measurement for protective relay test equipment
▪▪Impedance measurement
▪▪Efficiency tests
▪▪Polarity (direction) tests
▪▪Injection
▶▶Maintained
» » Injection continues without any time limitation.
▶▶Momentary
» » Injection continues only as long as the button is kept
depressed.
▶▶Max. time
» » Injection stops automatically when the preset maximum
time is reached.
▪▪Filtering
▶▶When filtering is selected, five successive readings are
averaged. The following can be filtered: Current, Voltage
and Extra items that are measured.
▪▪Off delay
▶▶The turning off of generation can be delayed after
tripping throughout a specified time interval that is
expressed in mains frequency cycles.
