GE Sverker 760 Current Injection Set
The SVERKER 760 is intended primarily for the secondary testing of protective relay equipment but virtually any type of single-phase protection can be tested. The unit is able to 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, as well as the testing of automatic reclosing devices.
The GE 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.
Brief Specs:
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.
