The Sverker 760 Relay Test Unit is the engineer's toolbox and features many functions that make relay testing more efficient. Its powerful measurement section can display time, voltage, current, Z, R, X, S, P, Q, phase angle and cos φ. The voltmeter can also be used as a 2nd ammeter, for example when testing differential relays and all values are presented on a single easy-to-read display. Automatic reclosing devices and directional protective equipment can be tested by means of the built-in variable voltage source which also incorporates a continuous phase shift function. Two or more Sverker units can also be synchronized, which enables the connection of three units into a basic 3-phase test set.

Applications
Relay Testing
Plotting excitation curves.
Current and voltage transformer ratio tests.
Burden measurement for protective relay test equipment.
Impedance measurement.

Injection Types
Maintained: Injection continues without any time limitation.
Momentary: Injection continues only as long as the button is depressed.
Maximum Time: Injection stops automatically when the preset maximum time is reached.

Filtering
When filtering is selected, five successive readings are averaged.

Off Delay
Turning off of generation can be delayed after a specified time interval expressed in mains-frequency cycles.
