The SVERKER 750 and SVERKER 780 relay test sets are the engineer's toolbox. The control panel features a logical layout, so SVERKER 650 users will find it comfortably familiar and will be able to start work right away. These instruments are 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 by testing one phase at a time, as well as a number of protective relay systems that require phase shifting, and automatic reclosing devices.

These instruments feature many functions that make relay testing more efficient. For example, they have a powerful measurement section that 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 second 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 efficiently by means of the built-in variable voltage source. In the SVERKER 780, this has a continuous phase shift function and adjustable frequency as well, and automatic reclosing devices can also be tested just as easily.

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 synchronised, which allows you to operate a basic three-phase test set.

Designed to comply with EU standards and other personal and operational safety standards, the SVERKER 750 and SVERKER 780 are also equipped with a serial port for communication with personal computers and the PC software SVERKER Win.The SVERKER 650 single-phase relay test set has been designed to incorporate the benefits gleaned from many years of experience in field relay testing. Compact and powerful, this instrument has a well-earned reputation for reliability and convenience and it provides all of the functions needed for secondary testing of almost all types of single-phase protection now available on the market.

The SVERKER 650 features logical design and construction, is extraordinarily easy to learn and use, and its compact design and light weight make it extremely portable. Auxiliary equipment for SVERKER 650 includes a test lead set and a rugged transport case. Another useful accessory is the ACA120 voltage source which makes it easier to test directional relays.

The SVERKER 650 is ideal for use in high voltage substations and industrial environments. The built-in capacitor provides phase shift when testing directional protective relays and a set of resistors can be used to divide voltages. This instrument is intended primary for secondary injection testing of protective relays and virtually all types of single-phase protection can be tested.
