SVERKER 750, the test engineer's toolbox.
The SVERKER 750 is a logical development from its eminent predecessor SVERKER 650, one of the world's most widely used relay testing units.
SVERKER 750 incorporates a host of new features, but still performs the same basic functions as its predecessor SVERKER 650.
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. What's more, the fully encapsulated control panel is easier to keep clean thanks, in part, to membrane-type keys.
The SVERKER 750 features many functions that make relay testing more efficient. To cite one example, its powerful measurement section can display (in addition to time, voltage and current) Z, R, X, S, P, Q, phase angle and cos phi.
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.
Thanks to its built-in variable voltage source, SVERKER 750 can also test directional protective equipment efficiently. Automatic reclosing devices can also be tested - just as easily.
Phase shifting and fine regulation of current are easy thanks to the built-in capacitor and set of resistors.
Designed to comply with EU standards and other personal and operational safety standards, SVERKER 750 is also equipped with a serial port for communication with personal computers and the PC software ProView PC750. Since the compact SVERKER 750 weighs only 18 kg (39 lbs), it's easy to move from site to site.
Using the small light-weight CSU 20A Current and Voltage Source together with SVERKER 750 gives the user two independent current sources, which is convenient when testing differential relays.
The PSS 750 Phase Selector Switch is designed to work with SVERKER 750 when testing three-phase relays, and simplifies phase switching, selecting type of fault and phase reversing, and gives a possibility to create a variable phase shift.
Two or more SVERKER 750 units can also be synchronized, which for example allows the user to connect three SVERKER 750's into a basic 3-phase test set.
