Description

The SVERKER 750/780 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 750/780 features 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
allows the user to operate a basic 3-phase test set.

Application

Relay Testing
SVERKER 750/780 is intended primarily for secondary testing
of protective relay equipment. Virtually all types of single-phase
protection can be tested. You can also test three-phase protection
that can be tested one phase at a time, and also a number of
protective relay systems that require phase shifting. Moreover,
automatic reclosing devices can be tested.
SVERKER 780 can test voltage relays with a frequency range from
15 Hz up tp 550 Hz.

Examples of what SVERKER can test

Overcurrent relays
Inverse time overcurrent relays
Undercurrent relays
Ground fault relays
Directional overcurrent relays
Directional ground fault relays
Overvoltage relays
Undervoltage relays
Directional power relays
Power factor relays
Differential protection (differential circuits)
Distance protection equipment (phase by phase)
Negative sequence overcurrent relays
