With its ease of configuration and its comprehensive range of facilities, including a variable-frequency voltage source with a continuous phase-shift function, Megger's self-contained Sverker 780 relay test set is an invaluable 'toolbox' for protection engineers, which is capable of testing almost any type of single-phase protection relay conveniently and efficiently.
You can also test directional protective equipment efficiantly by means of the built-in variable voltage source. In Megger SVERKER780 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, the SVERKER780 is also equipped with a serial port for communication with personal computers and the PC software SVERKER Win.
Sverker780 Extra Features:
Plotting excitation curves.
Current and voltage transformer ratio tests.
Burden measurement for protective relay test equipment.
Polarity (direction) tests.
Injection: Maintained, Momentary & Max. time.
Filtering: When filtering is selected, five successive readings are averaged.
Off delay: The turning off of generation can be delayed after tripping.
