SVERKER 750/780 Relay Test Sets SVERKER 750/780Relay Test Sets The engineer's toolbox for all single phase relay testing Stand-alone functionality Rugged and reliable for field use 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 9. 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 Examples of what SVERKER can test ANSI® No. Overcurrent relays 50 Inverse time overcurrent relays 51 Ground fault relays 50N, 51N Directional overcurrent relays 67 Directional ground fault relays 67N Directional power relays 32 Power factor relays 55 Differential protection (differential circuits) 87 Distance protection equipment (phase by phase) 21 Negative sequence overcurrent relays 46 Motor overload protection 51/66 Automatic reclosing devices 79 Voltage regulating relays Underimpedance relays 21 Time-delay relays Frequency relays (SVERKER 780) 81

SVERKER 750/780 Relay Test Sets 000ns Mac Uac FEATURES AND BENEFITS 1 Set of resistors Fine regulation of current and voltage thanks to the built-in set of resistors. 2 Start and stop conditions The timer's start and stop inputs respond to changes, voltage or contact closing/openings. The timer's start input is also used when testing autoreclosing relays, to synchronize two or more SVERKER units and to start generation with an external signal. 3 Display Presents time, current, voltage and other entities. Also used to make settings, after you enter the setting mode by pressing button...

SVERKER 750/780 Relay Test Sets SVERKER WIN (OPTIONAL) PC software for SVERKER 750/780 The SVERKER Win software makes fieldwork easier while providing neater reports. During the test the software enables you to record the currents and voltages as well as the trip time. The SVERKER is connected to the PCs serial port. Test results can be reported either directly with table and graph, or from an external program, e.g. Microsoft® EXCEL. SVERKER Win enables customised reports in an easy way. Very useful are the reference graphs, together with the current/voltage graph presentation for each test...
