The Megger Sverker 750 Relay Test Set is the engineer's toolbox. The control panel features a logical layout, SVERKER 650 users will find it comfortably familiar and will be able to start work right away.
The Programma Sverker 750 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. 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. The current source built into the Sverker750 can provide 0-10A, 0-40A, 0-100A, 0-250V AC or 0-300V DC.
Designed to comply with EU standards and other personal and operational safety standards, the SVERKER750 is also equipped with a serial port for communication with personal computers and the PC software SVERKER Win.
