Megger Sverker780 c/w Acc

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. Impedance measurement. Efficiency tests. 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.
